Cell Hypothesis is one of the fundamental standards of science. Credit for the plan of this hypothesis is given to German researchers Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.
Cells need nutrition in order to get the required elements. Which specific foods provide specific elements, and what do those elements do in the cell?
...
The major macromolecules are:
carbohydrates and lipids - made of carbon, hydrogen, and water.
proteins - provide nitrogen and sulfur.
nucleic acids - provide phosphate.
Answer:
A) Madison’s parents’ blood types may be either A & 0, or A & A.
B) Depending on her parents’ genotypes, Madison’s genotype may be either AA or A0
Explanation:
Since the A allele is dominant with respect to the 0, a person with blood type A may have either one (A0 genotype) or two A alleles (AA genotype). In contrast, a person with blood type 0 may only have two 0 alleles (00 genotype).
Because one of the sisters has type 0 blood, we have to assume that both of her parents have at least one 0 allele. There are two situations which may give rise to the described scenario (see Punnett squares):
Alternative 1: One of the parents has A blood type (A0 genotype), and the other has 0 blood type (00 genotype). Madison’s genotype may only be A0.
| 0 | 0
——————————
A | A0 | A0
——————————
0 | 00 | 00
Alternative 2: Both parents have A blood type and A0 genotypes. Madison’s genotype may be either A0 (probability of 2/3) or AA (probability of 1/3).
| A | 0
——————————
A | AA | A0
——————————
0 | 0A | 00
