Which two processes does this diagram most directly models?
svet-max [94.6K]

The correct answer is D. Homeostasis and transport of molecules

Explanation:

The diagram presented shows the movement of glucose from outside the cell to inside it. Also, this diagram illustrates this process occurs through the cell membrane and there is a higher concentration outside the cell.

This complex process illustrates the transport of molecules in the cell, which refers to a mechanism that allows molecules and substances to move in and out of a cell. Moreover, this process implies molecules (in this case glucose) move to one area with a lower concentration to preserve equilibrium as shown by the diagram. Additionally, this equilibrium is part of homeostasis which is a set of mechanisms to main an equilibrium in the cell, including appropriate levels of glucose and other substances.

Human ABO blood type is controlled by the I locus and has three possible alleles. The alleles which code for type A blood (IA) a
Oxana [17]

Answer:

1/8 (12.5 %)

Explanation:

Cross: IAi X  IAIB

F1: 1/4 IAIA 1/4 IAIB 1/4 IAi 1/4 IBi

Phenotypes:

- IAIA and IAi >> type A blood

- IBi >> type B blood

- IAIB >> type AB blood

Phenotypic frequency type A blood: 1/2  (i.e., 1/4 IAIA +  1/4 IAi) >>

Probability to have 3 offspring with type A blood: 1/2 x 1/2 x 1/2 = 1/8

The human ABO blood group is a system consisting of there different alleles: A, B, and O. This system is used in genetics as an example of codominance because both A and B alleles are expressed in heterozygous individuals (i.e., IAIB), whereas only the allele A is expressed in individuals that have A and O alleles (since O allele is recessive to the A and B alleles).
