Answer:

The correct answer will be option-A

Explanation:

The centrifugation of the blood shows that 45% of the blood is composed of the cellular content and 55% blood plasma or liquid.

Erythrocytes or red blood cell constitute for about 41% of the total blood cells which transports the oxygen by binding it to the haemoglobin. The presence of haemoglobin is the reason the cell appears red which cause the color of the blood to appear red.

The remainder of the cell is white blood cells or leukocytes which play important role in providing the defence mechanism against the pathogen.

Thus, option-A is the correct answer.

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Explanation:

In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).

A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.

For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have

Phenotype of parent: A short haired male and long haired female

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
