-The Difference Between Teosinte and Maize is About 5 Genes.

-One of the first scientists to fully appreciate the close relationship between teosinte and maize was George Beadle.

-The earliest events in maize domestication likely involved small changes to single genes with dramatic effects. We know the events were early because there is little variation in these genes between maize varieties, suggesting that modern varieties are descended from a single ancestor.

-Later changes in the evolution of modern maize involved many genes with small effects. 

-Over thousands of years, selective breeding generated the broad diversity of corn varieties that are still grown around the world today.

2- This type of light production is called bioluminescence.
3- A bulb produces a lot of heat in addition to light, a firefly's light is "cold light".
4- If a firefly's light-producing organ got as hot as a light bulb, the firefly would not survive the experience.
5- When oxygen is available, the light organ lights up, and when it is not available, the light goes out.
6 - The male fireflys glows for attracting the famale fireflys.

Dozens of genes work together to make a single caracteristic, and they can give you predisposition to illnesses.
2. There are variations of the same genes, they are callled alleles, an example of them is different hair textures, there isn't a gene for curly or straight hair, but variatons of the hair gene.
3. Our parents contribute equally with genes to us, and we can only gets genes from them. If we have alleles in common with our aunts, it's solely because her parents, parents of our parents, passed to her, and they have the same genes, but not explicit.
4. Each one of our cells has a copy of the first cell that was formed.
5. We are mutations of cells, and each new person born will have a difference that is a combination of two different types of genes.

-their fur changes color to match the rocks near their home

-THEY DIE TO EAGLES(also because there are is too many offspring and the home isnt that big)

-these predators are more likely to catch mice that dont match the color of their habitat

-basically, their fur changes color so they die harder

-also they are cute

- The organisms in our visual world like plants, animals and an occasional mushroom, account for less than 10 percent of the living species on the planet.

- Of all of the species identified so far, over 90% are microbial, accounting for more than half of the total mass of living things on Earth.

- Microbes decompose waste and carry out biochemical reactions that are essential to life

- The microbes that live inside and on our bodies outnumber our own cells by about 10 to 1

- Fireflies also glow to avoid other animals to attack them. They have a nasty tasting chemical called lucibufagens, and after a predator gets a bite, it associates the firefly's glow with its taste

- For the fireflies to create light, they have a specific cell in it's tail that creates luciferase protein, than it's carried out causing a chemical reaction. When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced.

- One species of firefly that can't make its own light, acquires it by eating others with light. These species of fireflies mimic the flashing pattern of other species. When the  male approaches to find a mate, he instead becomes food to this species.

- We should stop looking at species as living things and instead, look at speciation as a process of transient things.

They live under the rocks to camouflage and protect their selfs.

Not all the mouses have the same color beacuse they change it according to the rock they live in.

- Tubulin forms hollow tubes, called microtubules, that support the structure of the cell.

- Fiber is used by silkworms to build cocoons. People turn these cocoons into silk fabric.

- MaSp (major ampullate spidroin proten) makes up the black widow spider web.

-   To form the structure of the DNA  A pairs  with T and  C pairs with G
-  All of the parts of our DNA  work  together in larger  units  that we call genes
-  Each  gene is a set of instructions for building a specific protein
-  Genome is the name for a complete set of genes
- Genomes are a set of instructions to build a whole organism
-  Every persons Genomes has the same genes  organized in the same order but the sequences of the base changes  making each person unique.

-most times the species changes to adapt to their biome but sometimes they stay the same everywhere(example:horseshoe crab)

-it happens with reproduction

-oh and also natural selection is a thing

-if a animal doesnt have advantages to their biome(example:orange animal in green grass biome) they are more likely to be caught by predator

- so to avoid that the offspring better pray to be the color of the biome to y'know, not die

-thats about it actually

SPECIES CHARACTERISTICS:
-Interbreeding(potentially or actually )
-Don't reproduce with others groups
-look different
-Adapted to different resources 

-Species of bacteria are defined by how different their DNA sequence is.

-Fossil species are defined by the difference in their age,anatomy and where they are found.

If a process doesn’t have all of those traits, it isn’t considered natural selection.
-Variation means that for certain species, there are differences between individuals.
-Heritability means that the differences from those genes are passed through generations and are written in DNA.
-Reproductive advantage means that individuals with certain traits are more successful at reproducing than others, so those who have more favorable traits reproduce passing the genes to their offspring.
-Over multiple generations, unfavorable variations decrease in populations, and favorable ones become more common.

  • There is not one gene that specifies your skin, dozens of genes are involved in making the pigments that color your skin.
  • Genes interact with the environment to specify traits.
  • We inherit equal amounts of DNA from both parents.
  • We cannot inherit traits from our aunts, uncles, cousins or siblings.
  • Each of us has new variations in our DNA that were not present in our parents.

    - The whole human family is one species with the same genes;
    - Mutation creates slightly different versions of the same genes, called alleles;
    - This differences, they account for the variation we see in human hair color, skin color, height, shape, behaviour etc. 
    - These variations are useful because it helps populations change over time
    - it’s useful to think that mutation is a process that creates genetic variation]]>     2022-03-30 01:08:27 UTC https://padlet.com/gianim1/9t9g4ocrqr56y7tg/wish/2120452002     Natural Selection https://padlet.com/gianim1/9t9g4ocrqr56y7tg/wish/2173432913 -What is it?
    This is the process by which organisms best suited to their environment tend to survive and produce more offspring. Their theory of action was first fully explained by Charles Darwin and is now considered to be the primary process that gave rise to evolution.

    -How does natural selection work? 
    In natural selection, genetic mutations that favor individual survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive and reproduce.

    -Through this process of natural selection, favorable traits are passed on from generation to generation. Natural selection can lead to speciation, where one species produces a new and distinctly different species. It's one of the processes that drives evolution and helps explain the diversity of life on Earth.

    -Does Natural Selection Affect Humans?
    In natural selection, genes that confer a certain survival or reproductive advantage are passed on and persist in a population, while genes that lead to reduced survival or fewer offspring become fewer and fewer. There is no doubt that natural selection shaped human evolution in our more distant past.
