My mom is so modern and stylish.She is a nail artist.I like to consult with her before doing or buying something,because she always gives the right opinion.
My dad is also modern and i like to talk with him about different topics.He works as a private entrepreneur and his company sells fireplaces.His hobby is going to the gym and playing basketball.Also he likes skiing.
Mom and dad are really caring and understanding.They are ready to do anything for their children, namely for me and my sibling.
My sister is younger than me,her name is Ivanka. She's 11 and she studies at Maple Glen Elementary School in 5th grade.She is a really good artist.Sometimes it seems like she is a little copy of me.
Our whole family loves to travel,so almost every weekend we go somewhere just to walk or do anything else.]]> 2022-09-28 20:07:33 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2318207976 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2318275209 One thing about me,I really don't like being alone.I have a lot of friends and I can't feel lonely with them.Now we are separated by 7000 km,but they continue to support me. Most of them have been my friends since birth or first grade,so I can say that our friendship is really long and nice.
We are so creative and funny,so there is never a dull moment in our company.We can talk with each other about everything and it never feels embarrassing.They are like my second family.]]> 2022-09-28 21:14:40 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2318275209 Me as an Ukrainian folk dancer 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2319664600 I have been a folk dancer for 10 years.I was 4 when my mom sent me to the ensemble.It is called "Vykrutasyky".
since I was very young, I cannot remember my first feelings, but during this long time I always liked to dance.I practiced three times a week after school.I went on tour with the ensemble to other countries.І learned a lot in just 10 years.

There are basic methods of gaining knowledge that are common to all of science. At the heart of science is the scientific investigation, which is done by following the scientific method. A scientific investigation is a plan for asking questions and testing possible answers.
  Steps of a Scientific Investigation:
  1. Make observation
  2. Ask a question
  3. Form a hypothesis
  4. Test the hypothesis
  5. Draw conclusion
  6. Communication results

    Variables
An experiment generally tests how one variable is affected by another. The affected variable is called the dependent variable. The variable that affects the dependent variable is called the independent variable.
   Data
Experimenters need to decide how they will collect data.  Data can be qualitative, which mean descriptive data that couldn't be measured. Data can also be quantitative which means it can be measures and recorded numerically.

The sample size in an experiment directly affects the interpretation of the results.
Repetition is the repeating of an experiment, validating the results.
Errors are always possible in human endeavors. Scientists have ways to reduce the effects of errors on their data.

CER stands for Claim, Evidence, Reasoning. Science relies on strong evidence to support claims and an explantion of how the evidence supports the claim. Using CER can be espcially useful when arguing different sides of a bioethical question.  Bioethical questions are topics that may lead to different claims based on an individuals beliefs or ethics, our concept of right and wrong.]]> 2022-09-30 00:36:50 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2320240815 Scientific Theories 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2320246658 With repeated testing, some hypotheses may eventually become scientific theories. A hypothesis is a possible answer to a scientific question. A scientific theory is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence.

The theory of evolution by natural selection is a scientific theory. Evolution is a change in the characteristics of living things within a species over time. Evolution occurs by a process called natural selection. The theory of evolution by natural selection explains how living things are changing today and how modern living things have descended from ancient life forms that no longer exist on Earth. No evidence has been identified that proves this theory is incorrect. More on the theory of evolution will be presented in additional concepts.

The cell theory states that all living things are made up of cells, and living cells always come from other living cells.

The germ theory proposes that microorganisms are the cause of many diseases.

    What does     'Organization of Living Things' mean?
    We know it all starts with the cell. And for some species it ends with the cell. But for others, the cells come together to form tissues, tissues form organs, organs form organ systems, and organ systems combine to form an organism.

    Levels of Organization
    The living world can be organized into different levels. For example, many individual organisms can be organized into the following levels:

    • Cell: Basic unit of structure and function of all living things.
    • Tissue: Group of cells of the same kind that perform the same function. 
    • Organ: Structure composed of two or more types of tissues. The tissues of an organ work together to perform a specific function. Human organs include the brain, stomach, kidney, and liver. Plant organs include roots, stems, and leaves. 
    • Organ system: Group of organs that work together to perform a certain function. Examples of organ systems in a human include the skeletal, nervous, and reproductive systems.
    • Organism: Individual living thing that may be made up of one or more organ systems.

    Bonds are made when atoms give away, get or share valence electrons.
    Molecules and compounds are when atoms bond they make new substances.
    Valence electrons are the electrons in the outer energy level of an atom that can participate in interactions with other atoms. They are also the electrons that are farthest from the nucleus.
    In the electron dot diagram an element's chemical symbol is surrounded by dots that represent the valence electrons. An element never has more than eight valence electrons, so there can’t be more than eight dots per atom.
    Ionic bond: If an atom gives away electron(s) to another atom that needs them, the atoms become ionically bonded.
    Covalent bond: If two atoms share a pair (or 2 pairs or 3 pairs) of electrons, then they are covalently bonded.]]>     2022-10-26 00:08:17 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2356312310     Bonding in Carbon-The Covalent Bond 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2357659926 Carbon is a nonmetal in group 14 of the periodic table. The atomic number of carbon is 6 with an electronic configuration of 2,4.
    Valence electrons are the electrons in the outer energy level of an atom that are involved in chemical bond formation.
    A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. Covalent bonds form between atoms of nonmetals.Covalent bonds form because the shared electrons fill the outer energy level of each atom. This is the most stable arrangement of electrons.]]>     2022-10-26 16:58:19 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2357659926     Ionic Bonding 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2357674678 Ionic bond is a bond between ions resulting from the transfer of electrons from one of the bonding atoms to the other and the resulting electrostatic attraction between the ions.
    Electron transfer is when an atom with a low ionization energy encounters an atom with high electron affinity, it is possible for an electron transfer to occur.
    Electrostatic attraction-the force of attraction between opposite electric charges.
    The octet rule is an expression of the tendency for atoms gain or lose the appropriate number of electrons so that the resulting ion has either completely filled or completely empty outer energy levels.]]>     2022-10-26 17:06:59 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2357674678     Water and Life 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2369140859 Water (H20)-dihydrogen oxide or dihydrogen monoxide.
    Water-is a simple molecule,containing just three atoms.Almost 75% of its surface is covered with water.
    MOLECULES
    • Structures: tasteless,odorless,transarent.
    • Chemical structures: each molecule consists of one atom of oxygen and two atoms of hydrogen.
    WATER AND LIFE
    The human body is about 70% water.
    • Photosyntesis-in this process,cells use the energy in sunlight to change carbon doixide and water to glucose(H6H12O6) and oxygen.Water is a reactant in this process.The reaction of photosyntesis can be represented by the chemical equation.
    • Cellular respiration-in this process,cells break down glucose in the presense of oxygen and release carbon dioxide,water and energy.
    Water is involved in many biochemical reactions.As a result,just about all life processes depend on water.

    Compound is a substance that consists of two or more elements. A compound has a unique composition that is always the same.There are four major types of organic compounds:
    • Carbohydrates
    • Lipids
    • Proteins
    • Nucleic acids
    In a dehydration reaction, two monomers are joined together while in hydrolysis  polymers are broken down, separating a monomer away from the polymer chain.

    A monosaccharide, the monomer of carbohydrates, is a simple sugar such as fructose or glucose.
    If two monosaccharides bond together, they form a carbohydrate called a disaccharide.
    A polysaccharide is a complex carbohydrate that forms when simple sugars bind together in a chain. Polysaccharides may contain just a few simple sugars or thousands of them. Complex carbohydrates have two main functions: storing energy and forming structures of living things.]]>     2022-11-06 16:24:42 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2371801626     Lipids 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2371806021 A lipid is an organic compound such as fat or oil. Organisms use lipids to store energy.Lipids consist of repeating units called fatty acids.
    Fatty acids are organic compounds that have the general formula CH3(CH2)nCOOH, where n usually ranges from 2 to 28 and is always an even number.
    There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids.
    In saturated fatty acids, carbon atoms are bonded to as many hydrogen atoms as possible.
    In unsaturated fatty acids, some carbon atoms are not bonded to as many hydrogen atoms as possible. Instead, they are bonded to other groups of atoms.

    TYPES OF LIPIDS:
    • triglycerides: the main form of stored energy in animals.
    • phospholipids: the major components of cell membranes.
    • steroids: serve as chemical messengers and have other roles.
    Excess dietary lipids can be harmful.

The nucleic acid DNA consists of two polynucleotide chains. The nucleic acid RNA consists of just one polynucleotide chain.

    Each nucleotide consists of three smaller molecules:
    1. sugar
    2. phosphate group
    3. nitrogen base

    DNA contains the genetic instructions for the correct sequence of amino acids in proteins. RNA uses the information in DNA to assemble the correct amino acids and help make the protein.

    The cytoplasm has several important functions, including:
    1. suspending cell organelles.
    2. pushing against the plasma membrane to help the cell keep its shape.
    3. providing a site for many of the biochemical reactions of the cell.
    The cytoskeleton is a cellular "skeleton" that crisscrosses the cytoplasm. Three main cytoskeleton fibers are microtubules, intermediate filaments, and microfilaments.

    • Microtubles are the thickest of the cytoskeleton structures and are most commonly made of filaments which are polymers of alpha and beta tubulin.
    • Microfilament are the thinnest of the cytoskeleton structures and are made of two thin actin chains that are twisted around one another.

    • The endoplasmic reticulum (ER) is involved in the synthesis of lipids and synthesis and transport of proteins.
    • The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell.
    • Vesicles are also used as chemical reaction chambers. Transport vesicles, lysosomes, and peroxisomes are types of vesicles.
    • Vacuoles have secretory, excretory, and storage functions.
    • Centrioles are made of short microtubules and are very important in cell division.

    Most organelles are common to both cells,but plant cells have features that animal cells do not have: a cell wall, a large central vacuole, and plastids such as chloroplasts.

    • The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.
    • The central vacuole maintains turgor pressure against the cell wall.
    • Chloroplasts capture light energy from the sun and use it with water and carbon dioxide to produce sugars for food.

    The environment includes two types of factors: 
    • Abiotic factors are the nonliving aspects of the environment. (sunlight, soil, temperature, and water)
    • Biotic factors are the living aspects of the environment. They consist of other organisms, including members of the same and different species.
    An ecosystem is a unit of nature and the focus of study in ecology.
    The habitat is the physical environment in which a species lives and to which it is adapted.

    There are three types of biomes:
    • Terrestrial Biomes 
    (all land areas on Earth where organisms live)
    • Aquatic Biomes
    (water-based biome; freshwater or marine biomes which is salt water)
    • Freshwater and Wetland Biomes
    (aquatic biome such as a pond, lake, stream, or river in which the water contains little or no salt)

    Climate is the average weather in an area over a long period of time.Climate is generally described in terms of temperature and moisture.It influences plant growth, biodiversity, and adaptations of land organisms.

    Producers are organisms that produce food for themselves and other organisms.Producers are also called autotrophs. There are two basic types of autotrophs:
    • Photoautotrophs use energy from sunlight to make food by photosynthesis. (plants, algae, and certain bacteria)
    • Chemoautotrophs use energy from chemical compounds to make food by chemosynthesis.(some bacteria and archaea)

    Consumers(heterotrophs) are organisms that depend on other organisms for food.
    • Herbivores producers such as plants or algae.(deer, rabbits, and mice)
    • Carnivores consume animals.(lions, polar bears, hawks, frogs, salmon, and spiders).Carnivores that are unable to digest plants and must eat only animals are called obligate carnivores. Other carnivores can digest plants but do not commonly eat them.
    • Omnivores consume both plants and animals.(humans, pigs, brown bears, gulls, crows, and some species of fish)
    Also there are decomposers:
    • Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment.

    interdependence-living things that interact with other organisms in their environment and need other organisms in order to survive.
    Competition is a relationship between two species, or individuals of the same species, that strive for the same resources in the same place.
    Niche-role that a particular species plays in its ecosystem, including all the ways that the species interacts with the biotic and abiotic factors in the ecosystem.
    Character displacement-two species within the same area coexist and adapt by developing different specializations.

    PREDATION:
    Predation is a relationship in which members of one species (the predator) consume members of another species (the prey).
    Keystone species-predator species that plays a special role in its community because changes in its population affect the populations of many other species in the community.
    Adaptations-characteristic that an organism inherits that helps it survive and reproduce in a given environment.(camouflage)

    SYMBIOSIS:
    Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis:
    • Mutualism-both species benefit(flower-bee)
    • Commensalism-one species benefits while the other one is not affected(whale-barnacles)

    • Carbon dioxide is given off when dead organisms and other organic materials decompose.
    • Burning organic material, such as fossil fuels, releases carbon dioxide.
    • Carbon cycles far more slowly through geological processes such as sedimentation.
    • When volcanoes eruptions give off carbon dioxide that is stored in the mantle.
    • Carbon dioxide is released when limestone is heated during the production of cement.
    • Ocean water releases dissolved carbon dioxide into the atmosphere when water temperature rises.
    • Carbon dioxide is also removed when ocean water cools and dissolves more carbon dioxide from the air.

    • contains the nitrogen base uracil (U) instead of thymine,
    • contains the sugar ribose instead of deoxyribose.

    Types of RNA
    1. Messenger RNA (mRNA) copies the genetic instructions from DNA in the nucleus, and carries the instructions to the cytoplasm.
    2. Ribosomal RNA (rRNA) helps form ribosomes, the organelle where proteins are assembled.
    3. Transfer RNA (tRNA) brings amino acids to ribosomes, where they are joined together to form proteins.

    Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read, one codon at a time, to make a protein. 
    • Translation occurs at a ribosome
    • During translation, a protein is synthesized using the codons in mRNA as a guide.

    Possible types of mutations in chromosomes:
    1. Deletion: When a segment of DNA is lost, there is a missing segment in the chromosome.
    2. Duplication: When a segment of DNA is repeated, creating a longer chromosome.
    3. Inversion: When a segment of DNA is flipped and then reattached to the same chromosome.
    4. Insertion: When a segment of DNA from one chromosome is added to another, unrelated chromosome.

    Reproduction     is the process by which organisms give rise to offspring. It is one of the defining characteristics of living things. There are two basic types of reproduction:
    Asexual reproduction (involves a single parent)
    Sexual reproduction (involves two parents)

    • Asexual reproduction produces offspring that are genetically identical to each other and to the parent.
    • Sexual reproduction produces offspring that are genetically unique.
    • During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote.
    • Meiosis is the type of cell division that produces gametes.

How this happens depends on whether the cell is prokaryotic or eukaryotic.
    Prokaryotic cells have a single circular chromosome, no nucleus, and few other cell structures. 
    Eukaryotic cells, in contrast, have multiple linear chromosomes contained within a nucleus, and many other organelles.

    Most prokaryotic cells divide by binary fission(asexual fission)
    Steps in binary fission:
    • Step 1: DNA Replication
    • Step 2: Chromosome Segregation
    • Step 3: Separation

    Cell division in Eukaryotes
    2 main steps:

The eukaryotic cell spends most of its "life" in interphase of the cell cycle, which can be subdivided into the three phases, G1, S and G2.

    The cell cycle in prokaryotes is quite simple: the cell grows, its DNA replicates, and the cell divides.

    In eukaryotes, the cell cycle is more complicated.The mitotic phase (M) actually includes both mitosis and cytokinesis. This is when the nucleus and then the cytoplasm divide. The other three phases (G1, S, and G2) - interphase in which cell grows and prepares for dividing

    • The G1 checkpoint makes the key decision of whether the cell should divide.
    • The S checkpoint determines if the DNA has been replicated properly.
    • The mitotic spindle checkpoint occurs at the point in metaphase where all the chromosomes should have aligned at the mitotic plate.

    If something goes wrong cancer cells might be created in the humans body.Cancer is a disease that occurs when the cell cycle is no longer regulated. Cancer cells grow rapidly and may form a mass of abnormal cells called a tumor.

    My favorite ones are Genetics, Evolution, and Ecology. It is really interesting to learn about how species change over time and where they live, what they eat, etc..
    I didn't really like the Biochemistry unit though. It was a little tough for me as I don't like chemistry. But I still learned a lot.]]>     2023-06-07 12:56:51 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2617104575     Activities / Labs 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2617105228 There were a lot of labs, I worked with alive and dead animals, researching how they react to different conditions or what they have inside, for example, mealworms and frogs.
    Also Pasta Predator Lab was one of my favorites activities this year. I enjoyed going outside and experiencing this. 
    I reminded myself how to work with a microscope because I used to do it in Ukraine before.

How they relate to each other and what they do to keep our body working as it's supposed to.

Amoeba sisters videos are the best! Also little games such as edpuzzle or bioman are really helpful. I would also like more quizizz that we used to do at the beginning of the class. Those helped me to study at home really well.]]> 2023-06-08 23:36:11 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2618679703 External Fertilization 24ymalyuga https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2618697563 External Fertilization - process where the female releases her eggs from her body into water.

    I had a Patau Syndrome. It is a disease of trisomy 13, when it is copied or half copied. the symptoms are big head,small eyes,losing a scalp mostly over lips. Newborns usually do not survive with this syndrome for more than a couple months. This disease is not inherited and doesn't have current treatment yet.
    Also there are a lot of disorders such as Down Syndrome, Cystic Fibrosis, Huntington's Disease, etc. They are all mostly caused by a mutation of some trisomys.]]>     2023-06-09 00:41:35 UTC https://padlet.com/24ymalyuga/omxqqaz8e1elkilj/wish/2618729971
