1. Which of the following bones are located in the hand?

• A. fibula
• B. metacarpals
• C. metatarsals
• D. ulna

Correct answer: B

Rationale: The correct answer is B, metacarpals. The metacarpals are the bones located in the hand, making up the palm and connecting to the fingers (phalanges) and wrist bones (carpals). The fibula and ulna are located in the leg and arm respectively, while the metatarsals are found in the foot. The axial skeleton consists of bones down the center of the body, including the skull, vertebrae, and ribs, while the appendicular skeleton includes bones of the arms, legs, and their attachments to the axial skeleton.

2. Convert 354,000 millimeters to meters (m).

• A. 354 m
• B. 354 m
• C. 354,000 km
• D. 35,400 m

Correct answer: B

Rationale: To convert millimeters to meters, you need to divide by 1,000 since there are 1,000 millimeters in a meter. Therefore, 354,000 mm ÷ 1,000 = 354 meters. Choice A, '354 m,' is correct as it represents the converted value. Choice C, '354,000 km,' is incorrect as it suggests converting to kilometers instead of meters. Choice D, '35,400 m,' is incorrect as it is not the result of the correct conversion calculation.

3. Which of the following is NOT a function of progesterone in the female reproductive system?

• A. expression of secondary sexual characteristics, such as enlarged breasts
• B. stimulation of milk production in the breasts
• C. regulation and preparation of the endometrial lining of the uterus for potential pregnancy
• D. inhibition of contractions of the uterus as the ovum is released

Correct answer: A

Rationale: Progesterone plays a key role in the regulation and preparation of the endometrial lining of the uterus for potential pregnancy. It also inhibits contractions of the uterus as the ovum is released and stimulates milk production in the breasts. However, the expression of secondary sexual characteristics, such as enlarged breasts, is primarily influenced by estrogen, not progesterone. Therefore, choice A is the correct answer as it is not a function directly attributed to progesterone in the female reproductive system.

4. I know you'll be busy on your trip, but will you send me a postcard from Germany?

• A. Period
• B. Colon
• C. Question mark
• D. Exclamation mark

Correct answer: C

Rationale: The sentence is a direct question as the speaker is asking if the person will send a postcard from Germany. Therefore, the correct punctuation mark to use at the end of a question is a question mark. An exclamation mark (Choice D) is used to convey strong emotion or surprise, which is not the case here. A period (Choice A) is used for declarative statements. A colon (Choice B) is used to introduce a list or explanation, which is not needed in this context.

5. What is the scientific name for the building blocks of proteins?

• A. Residues
• B. Monomers
• C. Macromolecules
• D. Peptides

Correct answer: B

Rationale: Rationale: - Proteins are made up of long chains of amino acids. - Amino acids are the building blocks of proteins and are considered monomers. - Monomers are the individual units that can be linked together to form larger molecules called polymers. - In the context of proteins, amino acids are the monomers that are linked together through peptide bonds to form polypeptide chains, which then fold into functional proteins. - Residues refer to the specific amino acids within a protein after certain modifications or cleavages have occurred, so it is not the correct term for the building blocks of proteins. - Macromolecules are large molecules made up of smaller subunits, such as proteins, nucleic acids, and carbohydrates, but they are not the specific building blocks of proteins. - Peptides are short chains of amino acids linked by peptide bonds, but they are not the fundamental building blocks of proteins.
