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.

An energy-transferring compound in cells is a nucleotide known as
8090 [49]

Adenosine triphosphate (ATP) is a complex molecule which provides energy to the cells. This molecule is present in all the living organisms. The chemical energy which is obtained by the body by the breakdown of the food is captured by the ATP (Adenosine Triphosphate) molecules. This captured chemical energy is then transferred by it in order to fuel different body processes.

Hence, the answer is ATP (Adenosine Triphosphate).

A checkered hen mates with a checkered rooster. The genes for the checkered trait are codominant in both parents. What are the c
iVinArrow [24]

There are 75% chances that their offsprings will be checkered.

Explanation:

The gene version allele is received by an individual and if they are different then the gene of the parent which is dominating is expressed in the offspring. However, in the case of co dominance the offspring gets the trait of both parent alleles.

So, in this case the mating of checkered rooster and checkered hen with co-dominance in their trait of genes will produce checkered offspring with a chance of 75 percent as can be calculated by the punnet square. The result will be 3 out of 4 checkered offspring.
