Question 1 of 5

Which of the following substances is excreted by the sweat glands in response to the breakdown of proteins and the formation of ammonia?

Correct Answer: C

Rationale: The correct answer is Urea. Sweat glands excrete urea in response to the breakdown of proteins and the formation of ammonia. Urea is a waste product formed in the liver by the breakdown of amino acids. It is then excreted by the kidneys in urine and by sweat glands through perspiration. Urea plays a vital role in the excretory process by helping eliminate nitrogenous wastes from the body and maintaining proper physiological balance.

Question 5 of 5

Lithium has an atomic number of 3 and a mass number of 7. What is the number of protons in a lithium atom?

Correct Answer: D

Rationale: The number of protons in an atom is equal to its atomic number. In this case, lithium has an atomic number of 3, so it contains 3 protons. The mass number (7) includes both protons and neutrons, with the difference between the mass number and atomic number representing the number of neutrons. Therefore, the correct answer is 3 protons in a lithium atom.
