A theory.
Explanation:
Answer:
The correct dating methods will be:
Explanation:
The primate fossils presented in the question above must be submitted to the dating processes known as radiopotassium and biostratigraphic so that the age of these fossils can be determined as accurately as possible.
Radiopotassium dating is based on the half-life of potassium, which is equal to 40 years. The term half-life refers to the number of years it takes for half the number of atoms of the radioactive isotope to be destroyed. Thus, radiopotassium dating measures the amount of potassium present in a fossil and relates this amount to the half-life of potassium, thus being able to calculate the age of the fossil.
Biostratigraphic dating, on the other hand, allows the age of a fossil to be determined by being compared with the age of another fossil and the physical and structural composition that these fossils have.
Therefore, to determine the age of primate fossils, radiopotassium dating would first be used in some fossils. These would be used as a model during biostratigraphic dating, allowing confirmation of the age of other fossils.

Stomata, found mainly on the underside of plant leaves, absorb essential carbon dioxide for photosynthesis and control the plant's water balance through transpiration.
The stomata on plant leaves play a crucial role in the process of photosynthesis, which is how plants make their food. They are small openings or pores, primarily found on the underside of a leaf. Through these stomata, a plant absorbs carbon dioxide from the atmosphere which is essential for photosynthesis. Moreover, the stomata also control a plant's water balance through a process called transpiration. During transpiration, water vapor exits the plant via the stomata.

You're welcome, took the quiz.
Answer: Both combinations result in heterozygous dominant offspring, meaning the offspring will have a combination of red and white color. Therefore, the correct answer is c) Red and white cows (heterozygous dominant).
Explanation:
When a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), the offspring will inherit one allele from each parent. In this case, the red cow has two copies of the dominant allele for red color (RR), and the white cow also has two copies of the dominant allele for white color (WW).
The dominant allele for red color (R) is represented by a capital letter, and the dominant allele for white color (W) is also represented by a capital letter. Since both parents are homozygous dominant, their alleles do not carry the recessive allele for black color (r). The recessive allele for black color is represented by a lowercase letter.
When the red cow (RR) is crossed with the white cow (WW), the offspring will inherit one allele from each parent. Therefore, the possible combinations of alleles in the offspring are:
- Red cow (R) from the red parent and white cow (W) from the white parent: RW
- White cow (W) from the red parent and red cow (R) from the white parent: WR
It's important to note that this explanation assumes a simple Mendelian inheritance pattern and does not take into account other factors that could influence color inheritance in cows.
