It is used to conduct a successful experiment. As shown in the picture, there are six steps and they are very easy to follow. First, you ask a question or state your problem. Once you do that, you make a hypothesis which is a testable explanation. Now, you gather any needed materials to conduct your experiment and prepare a procedure. This is how you know how to do your experiment. You are finally at the fun part: the actual experiment. You can now test your hypothesis for the question. After the experiment, you record your data and your results. During this, you can ask yourself different questions about what happened during the experiment. Lastly, you make your conclusion by going back through your data and results. Now, you can figure out whether or not your hypothesis was correct or not and why.]]> 2018-04-18 20:44:28 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253205044 Animal Cell 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253206376 Below is an example of an animal cell. It also shows the parts of the cell which are very important to the cell. First we have the nucleus which uses DNA to regulate the activities happening in the cell. The cell membrane is a semi-permeable structure that maintains homeostasis by protecting and supporting the cell. The nuclear membrane is what controls what enters or what leaves the cell. There is also the plasma membrane that controls the movement of materials that come in and out of the cell. Cytoplasm acts as the cell's environment as it fills up the cell. The ribosomes, which are located in Golgi Apparatus, make proteins for the cell. The Golgi apparatus, also known as the Golgi body, is where proteins are packed and carried. Next is the rough endoplasmic reticulum (rough E.R.) and the smooth endoplasmic reticulum (smooth E.R.). The rough E.R. is where proteins are sorted and the site of secretion. The smooth E.R. is where detoxification and lipid synthesis occur. Lastly is the mitochondria. The mitochondria is the powerhouse of the cell is where ATP synthesis occurs. Plant and animal cells are quite similar, but plant cells have some organelles that the animal cell does not have. These organelles include a cell wall, chloroplasts, and a central vacuole. The cell wall is made out of cellulose and gives support for the cell. Chloroplasts are where photosynthesis occurs and the central vacuole contains cell sap which is a weak solution of sugar and salts.]]> 2018-04-18 20:50:31 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253206376 Plant Cell 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253206683 2018-04-18 20:52:02 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253206683 Mitosis vs. Meiosis 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253207330 Mitosis and meiosis are two very similar concepts, but they also have their differences. Mitosis has to do with growth and repair. Meiosis has to do with sex cells. Both processes produce daughter cells. The only difference between that is the number that they produce. In mitosis, two daughter cells are produced. In meiosis, four daughter cells are produced. In mitosis, all of the daughter cells that are produced are identical. In meiosis, the daughter cells are different because it creates genetic variability in the gametes. Also, meiosis has more stages than mitosis. Now, it is easier for you to tell the differences between mitosis and meiosis.]]> 2018-04-18 20:54:56 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253207330 Transcription and Translation 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253207929 In this unit, you learn about deoxyribonucleic acid, also known as DNA, that carries genetic instructions. You also learn about nucleotide structures. Nucleotide structures contain sugar, phosphate, and four different nitrogenous 
bases. The bases are adenine, thymine, cytosine, and
guanine. Adenine pairs with thymine and cytosine pairs with guanine. These bases are important in protein synthesis. During protein synthesis, transcription and translation occurs. Transcription is the process by which a DNA template is used to produce a single-stranded RNA molecule. Transcription happens in the nucleus. The gene sequence is now copied into messenger RNA. Also, thymine is now replaced by uracil. The messenger RNA then transfers to the cytoplasm where translation occurs. Translation is the process by which a mRNA strand is used to direct the production of a chain of specific amino acids. The mRNA is read by a ribosome and the ribosome starts making the protein. The protein is complete when the stop codon is read.

Punnett squares are used to predict genotypes and phenotypes of future offspring. To use a punnett square, you need a homozygous and/or heterozygous trait. These traits are showed by using capital and lowercase letters. For example, a heterozygous trait could be represented as Bb because the letters are different. A homozygous trait could be represented as BB or bb because the letters are the same. Uppercase letters means that the trait is dominant which also means that the trait is most likely to be shown. Lowercase letters mean that the trait is recessive which also means that the trait is less likely to be shown. To find likeliness of a certain trait, you place the heterozygous and/or homozygous parents above and on the side of the punnett square. Then, you will cross them like they are shown below. ]]> 2018-04-18 21:01:30 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253208982 Hominid Evolution 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253209742 The theory of evolution was proposed by Charles Darwin. Evolution is the process by which organisms that are better suited to environment survive and pass genetic traits on to offspring. Evidence of evolution include fossils, molecular biology, embryology, comparative anatomy, and biogeography. Fossils shows comparative anatomical characteristics that reveal common ancestry. Molecular biology DNA and protein sequences from organisms that show common ancestry. Embryology compare embryos of different vertebrates. Comparative anatomy shows homologous and vestigial structures. Biogeography shows patterns of past evolution in the natural geographic distribution of related species. There are also mechanisms for evolutionary change such as mutations, genetic drifts, natural selection, and gene flow. Evolutionary change is based on the passing of mutations to offspring. Mutations are changes in the DNA. Genetic drifts are the variation in the relative frequency of an existing gene. It can also be described as a random event of chance of a population surviving. Natural selection is the process of heritable traits becoming more or less common in a population. To make traits more common, organisms have to be better adapted and able to survive in their environment. Gene flow is a movement of genes from one population to another. Hominids are a good example of evolution. Humans, known as Homo sapiens, haven't always lived on this earth and didn't always look how they do now. Our brain sizes changed as well as our jaw sizes. For example, the Homo erectus lived between 1.89 million and 143,000 years ago. Their brain sizes were 900cm³ and their jaws were large and projecting. Homo sapiens have a brain size of 1300cm³ and small jaws. We have gotten smarter and jaws have gotten smaller. ]]> 2018-04-18 21:04:47 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253209742 Plant Transport 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253210338 In this unit, you learn about plant organs, plant tissues, and their processes. The plant organs include roots, leaves, stems, and flowers. The roots absorb water and nutrients from the soil. They have root hairs which increase surface area to absorb water and nutrients. They have a meristem which is in charge of new growth and a root cap which protects the meristem. The leaves capture light for photosynthesis. The stomata is where water exits and gas exchange occurs. The guard cells that surround the stomata control the opening and the closing of it. The stems carry water and food through the plant. It's also where transpiration occurs, the evaporation of water, and where cohesion and adhesion are used. The flower contains petals, which attract pollinators, and female and male reproductive organs. The female organs are the stigma, style, and ovary. The male organs are the anther, filament, and pollen. The flowers job is to enable flowering plants to reproduce. The plant tissues include the dermal tissue and the vascular tissue. The dermal tissue protects and prevents water loss. The vascular tissue is the transport of water/minerals (xylem) and the transport of food (phloem). Plants go through photosynthesis, cellular respiration, transpiration, and reproduction. Photosynthesis uses energy from sunlight to make food for the plant. Cellular respiration makes and releases ATP energy in the mitochondria. Transpiration is the loss of water from a plant's leaves and its stems. ]]> 2018-04-18 21:07:31 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253210338 Food Chain 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253210917 This unit talks about the flow of energy in ecosystems from organism to organism. These relationships can be shown by using a food web or food chain. A food web is a series of interconnected food chains. A food chain shows a path of energy from producer to consumer and how much energy is being transferred. In food webs and food chains, they have different levels for organisms. The first level is primary producer which are organisms who use the sun's energy to make their own food. The next level is primary consumer which are heterotrophs who feed on the primary producers. Then the secondary consumers feed on the primary consumers. Next, the tertiary consumers eat the secondary consumers. The tertiary consumer is usually the top of the pyramid. If not, it is the quaternary consumer who is at the top of the food chain and has no natural enemies. Also in this unit, you learn about two biogeochemical cycles: the water cycle and the carbon cycle. The water cycle is the recycling of water through evaporation, condensation, precipitation, runoff, groundwater, aquifers, respiration, transpiration, excretion, and decomposition. The carbon cycle is the recycling of carbon through respiration, photosynthesis, fuel combustion, and decomposition. Another topic of this unit is renewable and nonrenewable resources and how they impact the environment. Energy can be categorized in two main sources which are nonrenewable and renewable. Nonrenewable resources can not be remade or regenerated. They come from natural resources. On the other hand, renewable resources are obtained from different natural sources and can be replaced and be continuously used.]]> 2018-04-18 21:09:58 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253210917 Loss of Biodiversity 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253211482 Ecology is the study of all the interrelationships between organisms and their environment. In this ecology unit, populations and how they are affected are talked about. Limiting factors are abiotic or biotic factors that influence the population. Biotic factors are in the environment and have an increasing effect as population size increases. Abiotic factors are in the environment and affect the population regardless of their population density. A population can continue to grow until it reaches its carrying capacity which is the maximum population size they can reach. Factors such as salinity, temperature, light, and depth can affect aquatic biomes. Light is important for autotrophs in shallow water. Gases dissolve more in cold water than in warm water and the most two important gases are oxygen and carbon dioxide for marine life. Salinity is the measure of the total dissolved solids in water which is mostly salt. There are different ocean zones. The intertidal zone which is closest to shore. The neritic zone which lies over the continental shelf. The oceanic zone which is the open ocean past the continental shelf. The photic zone is the top 200 meters of water. The aphotic zone is water below 200 meters and the bentic zone is on the ocean floor. Many changes that occur in ecosystems can cause a loss in biodiversity. Factors such as habitat loss, degradation, and introduction to invasive species can cause a loss in biodiversity. A loss of biodiversity can destabilize ecosystems and make them more vulnerable.]]> 2018-04-18 21:12:26 UTC https://padlet.com/1302601/wqiij64dyho3/wish/253211482 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/253213318 Unit 1: Scientific Processes

It talks about cohesion and adhesion. Cohesion is when water sticks to water. Adhesion is when water sticks to other surfaces. It also talks about surface tension which is how difficult it is to break or stretch the surface of water. In surface tension, hydrogen bonds hold water molecules together so tight that the water's surface acts as if it is a membrane. Two water property terms that are important are hydrophilic and hydrophobic. When something is hydrophilic, it has the tendency to dissolve in or be mixed with water. In fewer words, it likes water. When something is hydrophobic, most likely nonpolar substances, they have the tendency to exclude water molecules meaning that it doesn't like water. Water works differently in heat and in cold. Water absorbs heat from warm air and releases heat from cool air. Also, when frozen, water expands. As said, there are many different properties of water that are very important to know.]]> 2018-04-21 12:44:11 UTC https://padlet.com/1302601/wqiij64dyho3/wish/254047254 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/254047877 Atherosclerosis: when plaque builds up in the walls of the arteries

The brain itself has parts that include the frontal lobe, the parietal lobe, the temporal lobe, and the occipital lobe. They each also have different functions. The temporal lobe's unction is evaluating consequences. The parietal lobe's function is reading and speech.
The temporal lobe's function is hearing and smelling. The occipital lobe's function is vision. Next is the circulatory system which contains the heart. Blood flows through the heart in different paths. Blood flows from the upper body to the heart by the superior vena cava. Blood flows from the lower body to the heart by the inferior vena cava. Blood components are also important in the circulatory system. The four components of blood are plasma, red blood cells, white blood cells, and platelets. Plasma controls body temperature. Red blood cells, also known as erythrocytes, transports oxygen. White blood cells, also known as leukocytes, guards the body against infections. Platelets, also known as thrombocytes, helps with blood clotting. Next is the human immune system. The germ theory of disease is discussed here. The theory is that diseases are caused by the invasion of the body by microorganisms. The first defense of your immune system is the skin. The second defense is the inflammatory response of the actions of interferons, and fever. There is medicine you can take to protect yourself from diseases such as vaccines and antibiotics. Vaccines can stimulate the immune system with an antigen. Antibiotics can kill bacteria and some antiviral medications can slow down viral activity. If medication is misused, it can cause them not to work as well and re-emerge of diseases that were thought to be under control. The last system is the reproductive system. Parts of the reproductive system include male structures and female structures. The male structures are the vas deferens, testes, penis, urethra, epididymis, prostate gland, and the seminal vesicle. The vas deferens is a long duct where the sperm travels through. The testes are where sperm production occurs. The penis is the male organ for sexual intercourse. The urethra carries urine from the bladder to the outside of the body. The epididymis is where immature sperm matures. The prostate gland controls urination and produces minerals and sugar found in semen. The female structures include the ovaries, the fallopian tubes, the vagina, the uterus, and the cervix. The ovaries are where egg cells and hormones are produced. The fallopian tube is what the egg travels through from the ovary to the lower part of the uterus. The vagina is a canal that joins the cervix to the outside of the body. The uterus is where the home of the developing fetus The cervix is the lower part of the uterus that dilates during childbirth to allow the passage of the baby.]]> 2018-04-21 14:00:24 UTC https://padlet.com/1302601/wqiij64dyho3/wish/254052238 The Steps of the Scientific Method 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/254182740 This video talks about the steps of the scientific method. It explained how the scientific method is "a way to ask and answer scientific question." The steps that they go through are, ask a question, make observations, form a hypothesis,
design an experiment and test your hypothesis, analyze the data, and draw a conclusion. The scientific method is used to answer questions you have about any observations and inferences you or someone else has. It's the same process that scientists do when they conduct experiments. Make sure that when you are using the scientific method that you know that your results won't be perfect. These steps can be repeated as needed and your experiment can be repeated as well. Scientists repeat steps and redo their experiments as well. Nothing is perfect, that's why the scientific method is so helpful.]]> 2018-04-22 20:39:07 UTC https://padlet.com/1302601/wqiij64dyho3/wish/254182740 Introduction to Cells 1302601 https://padlet.com/1302601/wqiij64dyho3/wish/254182954 This video takes you on a tour about cells.
