a
Explanation:
stamen are the male productive organs in a flower where anthers produce pollen grains while pistil is the female productive organs in a flower where the stigma will receive the pollen grains
The limitations of cell size are:
1) Surface area to volume ratio
2) Nucleo cytoplasmic ratio
3) Fragility of cell membrane
What are the cause of limitations on cell size?
The need for a surface area of sufficient area to allow the cells function→.
→If the surface area of cell increase volume increase to the cube of the linear increase.
→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.
Examples are muscle cells.

Answer:
a.The phenotypic proportions obtained after having the genotypes are 50% marbled seeds, 25% spotted and dotted seeds since they are codominant, 25% spotted seeds.
b. Taking into account the F1 genotypes in the previous point, the expected phenotypes for the first crossing are 100% marbled seeds and for the second crossing 100% dotted seeds.
Explanation:
Let's suppose:
Marbled allele: M
Spotted allele: S
Dotted allele: D
Allele for Clear: C
a. Because both crosses were between homozygous parents, the entire F1 genotype is the same.
For the first crossing the descendants have the MS genotype, and for the second crossing the descendants have the DC genotype. It is enough to make a Punnett square to obtain the different combinations of genotypes between the crossing of MS and DC.
When the structure and function of an organism adjusts to its environment it is adapting.
