1. What is the tough, fibrous connective tissue that attaches muscle to bone?

• A. Fascia
• B. Perimysium
• C. Tendon
• D. Ligament

Correct answer: C

Rationale: Tendons are the correct answer as they are the tough, fibrous connective tissues that attach muscle to bone. They play a crucial role in transmitting the forces generated by muscle contraction to the bones, facilitating movement. Fascia surrounds muscles and provides support, perimysium is the connective tissue sheath around muscle fibers, and ligaments connect bone to bone, stabilizing joints, which makes them distinct from tendons.

2. Where is the scapula in relation to the olecranon?

• A. Distal
• B. Lateral
• C. Ventral
• D. Superior

Correct answer: D

Rationale: The correct answer is D: 'Superior.' The scapula is located superior to the olecranon. In anatomical terms, 'superior' refers to a position above or higher than a reference point. 'Distal' is a term used to describe a position farther away from the point of attachment or origin. 'Lateral' refers to a position further away from the midline of the body. 'Ventral' refers to the front or anterior side of the body. In this case, the scapula being superior to the olecranon means it is positioned above the olecranon bone.

3. How does an increase in temperature generally affect the solubility of most solid solutes in a liquid solvent?

• A. It increases solubility
• B. It decreases solubility
• C. It has no effect on solubility
• D. It depends on the nature of the solute

Correct answer: A

Rationale: In general, increasing temperature tends to increase the solubility of most solid solutes in liquid solvents. This occurs because higher temperatures provide more energy for the solvent molecules to break the solute-solvent attractive forces and allow more solute to dissolve. The increase in temperature facilitates the dissolution process by overcoming the intermolecular forces that hold the solute particles together. Choice B is incorrect because higher temperatures typically lead to greater solubility. Choice C is incorrect as temperature changes usually impact solubility. Choice D is incorrect because although the nature of the solute can influence solubility, the general trend is that higher temperatures enhance solubility for most solid solutes in liquid solvents.

4. Which of the following is NOT a common symptom of pregnancy?

• A. Fatigue
• B. Nausea
• C. Increased urination
• D. Loss of appetite

Correct answer: D

Rationale: The correct answer is D, 'Loss of appetite.' Loss of appetite is not a common symptom of pregnancy. In fact, many pregnant individuals experience an increase in appetite due to hormonal changes and increased energy needs during pregnancy. Fatigue, nausea, and increased urination are more commonly reported symptoms during pregnancy. Fatigue is often experienced due to hormonal changes and the body's increased metabolic demands during pregnancy. Nausea, commonly known as morning sickness, is a well-known symptom experienced by many pregnant individuals. Increased urination is a common symptom in pregnancy due to hormonal changes leading to increased blood flow to the kidneys and increased fluid processing by the body.

5. DNA has both a 'sense' and 'antisense' strand. What is true about the antisense strand?

• A. It runs 5' to 3'.
• B. It runs 3' to 5'.
• C. It is used in replication.
• D. It is the direction DNA is stored.

Correct answer: B

Rationale: The correct answer is B: 'It runs 3' to 5'. The antisense strand runs in the 3' to 5' direction, complementing the sense strand. Choice A is incorrect as the antisense strand runs in the opposite direction, which is 3' to 5'. Choice C is incorrect because the antisense strand is not directly involved in replication. Choice D is incorrect as the direction DNA is stored is not determined by the antisense strand.
