C. A wall of stones and mortar

This would act as a model describing the cell membrane.

Explanation;

A cell membrane is made up of a phospholipid bilayer with embedded proteins.

A cell membrane hold the different components of the cell together and to protect it from the environment outside the cell. It acts as a boundary between the inside environment and the outside environment of a cell.

It regulates the materials that enters and exits the cell; through selective movement of substances in and out of the cell.

In cats grey color (G) is dominant to white color (g). If a white female has kittens with a heterozygous male, and the mother is

Scrat [10]

Answer:

Rounding down to the nearest whole number, 5 Kittens will be white.

Explanation:

<u>Available data:</u>

grey color (G) is dominant
white color (g) is recessive
white female, gg
heterozygous male, Gg
9 Kittens

Cross:

Parental) Gg x gg

Phenotype) Grey White

Gametes) G g g g

Punnet square)

G g

g Gg gg

F1) Genotypes:

1/2 = 50% will be Gg

1/2 = 50% will be gg

Phenotypes:

1/2 = 50% will be Grey (Gg)

1/2 = 50% will be white (gg)

To calculate the number of kittens that will be white, we need to consider the proportions of cats that will be white in the F1 and that the total number of kittens is 9. So

100% of the progeny ------------------------------- 9 kittens

50% of the progeny----------------------------------X = (50 x 9)/100 = 4.5 kittens ≅ 5 Kittens

A cat can not have 4.5 kittens, so we must round down to the nearest whole number. 4.5 ≅ 5 Kittens
