Which of the following statements is incorrect?a. Sebaceous glands are attached to hair follicles and secrete sebum which protects and lubricates skin. b. Sudoriferous glands release perspiration into hair follicles or onto the surface of the skin through pores. c.Ceruminous glands produce a waxy substance which protects the genitals."d. All of these statements are correct.

The correct answer is option c. "Ceruminous glands produce a waxy substance which protects the genitals".

Explanation:

It is incorrect that ceruminous glands produce a waxy substance which protects the genitals. The ceruminous glands are not located in the genital area, ceruminous glands are specialized sudoriferous glands located in the the external auditory canal. A normal ear have between 1,000 and 2,000 ceruminous glands, which produce the ear wax that protects this zone.

explanation:

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.
