Which of the following is an example of a biological macromolecule?

Exocrine glands secrete their products into ducts that carry them to the target organs. In contrast, endocrine glands secrete their products directly into the bloodstream, which carries them to target cells throughout the body.

Water has a high specific heat capacity, which means it can absorb and store a large amount of heat energy without significantly changing in temperature. This helps moderate the temperature fluctuations of the air near the coast, as water can store heat during the day and release it at night, or vice versa.

Psoriasis is a chronic skin condition that causes red, scaly patches on the skin. It is not contagious, and it is not caused by any microorganism. It is believed to be an autoimmune disorder where the immune system attacks healthy skin cells.

The kidneys are the primary organs involved in the excretion of nitrogenous wastes. Nitrogenous wastes are mostly products of protein metabolism in the liver. One of the common nitrogenous waste products is urea, which is excreted through the kidneys.

Concentration of H+ in the solution = 10 −1 M

pH= -log(10 −1)

The pituitary gland produces prolactin, which regulates milk production

The endocardium lines the interior structures of the heart. It is a thin, innermost layer of the heart wall that lines the heart chambers and valves. It is composed of subendocardial connective tissue and endothelial cells that are continuous with blood vessel endothelium.

Uracil is the nucleotide that is only found in RNA. The other nucleotides are found in both DNA and RNA

ATP is produced by a series of reactions that occur in the mitochondria. The mitochondria have a double membrane structure, with an inner membrane that is folded into cristae. These cristae contain the enzymes and proteins that are involved in the process of cellular respiration, which converts glucose and oxygen into ATP and carbon dioxide.

From the heart, blood flows through major arteries, which then branch to give rise to arterioles, which then divide into capillaries that deliver blood to the target organ.
