Answer:

A. Cell membrane

Explanation:

The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.

The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.

Thus, the correct answer is option (A).

When a BB male and a Bb female are crossed, 50% BB and 50% Bb genotypes are produced and a 100% black phenotype.

The entire number of genes that an organism receives from its parents makes up its genotype. Alleles, which are pairs of these genes, are found. One gene is dominant and one gene is recessive in each allele.

The dominant gene is always expressed in a cross if it is present. Only when a pair of alleles is made up of two recessive genes does the recessive gene express itself. In this instance, the white fur is subordinate to the black fur. White fur is represented as b, while black fur is represented as B.

We can see that when we cross the BB male and Bb female, we will get a genotype that is 50% BB and 50% Bb, as well as a phenotype that is 100% black fur.

Parents: BB x Bb

Gametes: B, B, and B, b

Offspring: BB, BB, Bb, Bb

The genotypic ratio = 1:1

The phenotypic ratio = 1:0

Genotype probabilities:

P(BB) = 2/4 = 0.5 or 50%

P(Bb) = 2/4 = 0.5 or 50%
