After reading the paragraph below, answer the questions that follow.
the skin is the body's largest organ. it's made up of many different types of cells. oils, produced by the sebaceous glands, prevent the skin from drying and splitting. the pigment melanin, produced by melanocytes in the epidermis, protects the skin from the harmful effects of ultraviolet radiation. sweat, released through ducts to the skin surface, to cool the body. the types of cells that produce these compounds have different numbers of specific organelles, depending on their function. melanocytes use many enzymes to produce melanin. based on their function, you would expect melanocytes in the skin to have a higher than usual number of after reading the paragraph below, answer the questions that follow.
a. ribosomes.
b. lysosomes.
c. microtubules.
d. chloroplasts.

A

Explanation:

Enzymes, that speed up biochemical reactions in the body, are chiefly made of proteins. Proteins, on the other hand, are manufactured by ribosomes. Therefore, for melanocytes to produce required melanin, they need enough ribosomes to process the many enzymes required to catalyze the production of the pigment.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
