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.
The term that refers to all areas of Earth where all life exists is call the Biosphere
B. Nucleus (because the nucleus is to the organelles, like the brain to our organs).
Answer:
It has deeply impacted the evolution of life and continues to shape the ecology of countless species.
Explanation:
You are repaying the oxygen deficit when you have elaborated breath after a long workout.
We can define oxygen deficit as the difference between the oxygen that our body needs during a workout and the one that it gets, which is not enough.
We can tell when our body is repaying the oxygen deficit when our breath is elaborated. What our body is trying to do is to expel carbon dioxide and take as much oxygen as it needs with quick and short breaths.
In conclusion, elaborated breath is a sign that we are repaying the oxygen deficit.
