The question is incomplete and the diagram is also not given. So the diagram is attached below and the complete question is as follows:

The following models show one large cell (A) and four small cells (B).

Which of the following states why one of the models is better for moving more nutrients in and out of the cell?  

A. B is better because it has more surface area.

B. A is better because it has less surface area.

C. A is better because it has more volume.

D. B is better because it has more volume

A. B is better because it has more surface area.

Explanation:

The movement of nutrients in a cell depends on the surface to volume ratio. More is the surface to volume ratio, better will be the movement of nutrients in and out of the cell.

In the given model, small cells (B) has more surface to volume ratio as surface area of B is larger, so, the model B is better for moving more nutrients in and out of the cell.

Hence, the correct option is "A".

option c is the correct answer.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
