Natural Selection is the process by which the most adapted, or fittest, species survive and the least adapted, or unfit, species do not survive. An example of Natural Selection is if there are two species of birds that eat the same thing, but one of the species has a beak that makes it harder to eat the food, naturally the species that has the beak fit to eat that food will survive. The species that is not fit to eat that food will either adapt or will be unable to survive. Evolution is a species adapting to the enviornment over a period of time. There is microevolution and macroevolution.
100% will have that allele. Homozygous means the alleles are the same for every gamete, for example looking at Mendel's pea plants, if the allele for the trait of growing tall is T and the allele for growing short is t, a homozygous tall pea plant would have the genotype TT, meaning all of its alleles are tall
If you use more than one independent variable at a time, and will observe a change, you will not know which variable contributed to a changed result.
Liver contains a enzyme called catalase. When hydrogen peroxide (H2O2) is added to liver, a chemical reaction occurs which results in the production of oxygen gas (O2) and liquid water (H2O).
