Answer:
i don't know if im right but honestly i could be A B or C
Explanation:
but i would say if its humans adapting to the environment and if an animal probably the same thing but maybe A more than C
Answer:
1. Radiometric dating
2. Relative dating is used to determine the age of fossils or rock layers by by comparing it to similar rocks and fossils of known ages.
3. The youngest rock layers are at the top and the oldest are at the bottom, which is according to the law of superposition.
4. Tribolite and Pecten fossils
Fossils are used to determine the ages of rock layers. Index fossils are the most useful in determining relative aging. Index fossils are of organisms that lived for a short period of time. An index fossil allows a scientist to determine the age of the rock it is in. So if they are found in a particular age, it means they belong in that age.
5. Scientists commonly use radioactive dating methods by using radioactive decay cloak of certain elements such as potassium or carbon to date fossils or rocks.
6. Law of superposition because in terms of finding the age of the rock as an object, all that needs to be identified are the layers of the rock.
7. The nuclear decay of radioactive elements are a process that behaves in a clock-like fashion which makes it a useful tool for determining the exact age of fossils or rocks.
Dominant: the more common trait (brown hair)
Recessive: a trait that doesn't show up unless both parents carry it (blue eyes)
Co- dominant: both traits show up and co- exist (AB blood)
Incomplete dominance: when a dominant gene does not completely mask a recessive gene so they blend (pink flower)
Phenotype: physical trait- able to be seen (stripes on a zebra)
Genotype: genetic makeup of an organism - genetic trait
Hetrozygous: different (Bb)
Homzygous dominant: same and dominant (bb) and (BB)
Purebred: same as homzygous- has same alleles (bb) and (BB)
Hybrid: also known as heterozygous traits

Answer:
F (pp) = 0.04
F (Pp) = 0.32
F (PP) = 0.64
Explanation:
Studying population genetics, we used the Hardy-Weinberg equilibrium model. In the case of snails, the H-W principle predicts that the total number of cases in the population should follow the following equation: PP + 2.Pp + pp = 200.
If a population has 200 snails and 8 are affected by a recessive condition, we have 4% affected, or 0.04.
This means that 0.04 corresponds to p², and p corresponds to 0.2.
Therefore, P is equal to 0.8 because p + P = 1.
Knowing the allele frequencies, we go to the frequency of the genotypes.
F (pp) = p² = 0.04 = 8 snails
F (Pp) = 2.Pp = 0.32 = 64 snails
F (PP) = P² = 0.64 = 128 snails
