Answer:
I would say B
Explanation:
Because atural selection is the mechanism for how evolution occurs over time. Basically, natural selection says that individuals within a population of a species that have favorable adaptations for their environment will live long enough to reproduce and pass down those desirable traits to their offspring.
Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
answer: The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.

The correct answer for this question is A. Law of segregation.
All individuals have two alleles for a given trait. According to Mendel's Law of segregation, these alleles are passed down one each from both mother and father.
Explanations;
According to this law of segregation the allele pairs separate or segregate during the formation of gamete, during the process of meiosis, leaving each cell with a single allele for each trait, and randomly unite during fertilization. One pair of allele comes from the mother while the other pair comes from the father, and joins together to form a diploid cell. Therefore, organisms inherit two alleles for each trait one from each parent.
The _Embryo_ is the answer
