Question 1

Which of the following best describes the relationship between anatomy and physiology?

Accepted Answer

Anatomy studies the structure of the body, while physiology studies the function of those structures.

Question 2

Which imaging technique is most useful for visualizing soft tissues such as the brain, and why?

Accepted Answer

Magnetic resonance imaging (MRI), because it uses a powerful electromagnet to distinguish soft tissues.

Question 3

A patient presents with a blood pH of 6.9. Which of the following best describes the physiological consequence?

Accepted Answer

The patient is at risk for severe physiological dysfunction, including tremors, fainting, or death.

Question 4

Which of the following is an example of a negative feedback loop in the human body?

Accepted Answer

Regulation of body temperature by sweating when hot and shivering when cold.

Question 5

Which of the following best explains why trans fats are considered unhealthy?

Accepted Answer

Trans fats are difficult for the body to digest and tend to deposit in arteries, increasing the risk of coronary heart disease.

Question 6

Which of the following is the correct order of structural organization in the human body, from simplest to most complex?

Accepted Answer

Chemical level → Cellular level → Tissue level → Organ level → Organ system level → Organismal level

Question 7

A scientist is studying the structure of the palmaris longus muscle in a group of individuals. Which subdiscipline of anatomy is she most likely practicing?

Accepted Answer

Gross anatomy

Question 8

Which of the following best describes the amphipathic nature of phospholipids and its importance in cell membranes?

Accepted Answer

Phospholipids have both hydrophilic heads and hydrophobic tails, allowing them to form the structural foundation of cell membranes.

Question 9

Which of the following equations correctly represents the relationship between pH and hydrogen ion concentration $$[H^+]$$?

Accepted Answer

$$pH = -\log_{10} [H^+]$$

Question 10

Which of the following best describes the role of enzymes in biological reactions?

Accepted Answer

Enzymes lower the activation energy required for reactions, allowing them to proceed faster without being consumed.

Question 11

A patient is unable to digest lactose due to a deficiency in the enzyme lactase. Which type of macromolecule is directly affected by this deficiency?

Accepted Answer

Carbohydrates

Question 12

Which of the following is a correct example of complementary base pairing in DNA?

Accepted Answer

Adenine (A) pairs with Thymine (T)

Question 13

Which of the following best describes the function of ATP in cells?

Accepted Answer

ATP stores and releases energy for cellular work such as transport, mechanical, and chemical processes.

Question 14

Which of the following is a real-life example of positive feedback in the human body?

Accepted Answer

Amplification of labor contractions by oxytocin during childbirth.

Question 15

Which of the following best explains why proteins lose their function when denatured?

Accepted Answer

Denaturation disrupts the protein’s conformation, which is critical for its function.

Question 16

Which of the following best describes the law of mass balance as it applies to homeostasis?

Accepted Answer

The total amount of a substance the body takes in must equal the amount it loses to maintain a steady state.

Question 17

Which of the following is a function of the integumentary system?

Accepted Answer

Protects deeper tissues from injury and synthesizes vitamin D.

Question 18

Which of the following best describes the difference between saturated and unsaturated fatty acids?

Accepted Answer

Saturated fatty acids have no double bonds between carbons, while unsaturated fatty acids have one or more double bonds.

Question 19

Which of the following best describes the central dogma of molecular biology?

Accepted Answer

DNA is transcribed into RNA, which is then translated into protein.
