A. CnH2n
B. CnH2n+2

4. How many amino acids can make up a protein?

A. 10-20
B. 50-100
C. 100-500
D. 1000+

Correct answer: A

Rationale: Rationale: Proteins are made up of long chains of amino acids. There are 20 standard amino acids that are commonly found in proteins. The sequence and arrangement of these amino acids determine the structure and function of a protein. While proteins can vary in size and complexity, the number of amino acids typically ranges from around 10 to 20 in smaller proteins to hundreds or even thousands in larger proteins. Therefore, the range of 10-20 amino acids is the most accurate representation of the number of amino acids that can make up a protein.

5. What is the primary hormone released by the parathyroid glands?

A. Insulin
B. Calcitonin
C. Parathyroid hormone (PTH)
D. Thyroxine

Correct answer: C

Rationale: The primary hormone released by the parathyroid glands is Parathyroid hormone (PTH), which plays a crucial role in regulating calcium levels in the body. Insulin is produced by the pancreas to regulate blood sugar levels and is unrelated to the parathyroid glands. Calcitonin is produced by the thyroid gland and helps regulate calcium levels but is not the primary hormone released by the parathyroid glands. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism and is also not released by the parathyroid glands. Therefore, the correct answer is C: Parathyroid hormone (PTH).

6. What is the muscular sac in the female body that nourishes and protects a developing fetus?

A. Ovary
B. Fallopian tube
C. Uterus
D. Vagina

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus is a muscular sac in the female body where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment to the developing fetus and protects it throughout gestation. The ovaries produce eggs, the fallopian tubes transport eggs from the ovaries to the uterus, and the vagina is the canal leading from the uterus to the outside of the body. Therefore, the uterus is the specific organ responsible for nourishing and protecting a developing fetus in the female body.
