Answer:
Option (B).
Explanation:
Heart is the main pumping organ of the body. The human heart is divided into four chambers that are right atria, right ventricles, left atria and left ventricles.
The left and right ventricles can easily be distinguished on the basis of their thickness. The right ventricle is less thicker than left ventricle. The thickness of right ventricle is 9mm whereas the thickness of left ventricle is around 40mm.
Thus, the correct answer is option (B).
The antidiuretic hormone, otherwise called vasopressin is made in the region of the brain called hypothalamus. The cells of the hypothalamus excrete this hormone through the connection they have with the pituitary gland. From this gland, the hormone is released into the bloodstream and eventually comes down to kidneys, affecting the kidney tubules, making them conserve water by transporting them back to the bloodstream.
The answer is either a or c
The intermediate color or rather condition, in this case "roan", is a result of two alleles being codominant. Codominance occurs when the phenotype (or the physical expression of the gene) of a heterozygote individual expresses both the alleles in a pair of genes. In the given situation, both parents are homozygotes.
