$$Fitness = Survival \\times Reproductive \\ Success$$

Question 1

Which of the following best describes the primary function of the sympathetic nervous system?

Accepted Answer

It prepares the body for 'fight or flight' responses by increasing heart rate and inhibiting digestion.

Question 2

Which scenario best illustrates the activation of the parasympathetic nervous system?

Accepted Answer

A person’s digestive processes speed up and heart rate slows after eating a meal.

Question 3

Which of the following is an example of a natural selection process?

Accepted Answer

A giraffe with a longer neck survives and reproduces more successfully in an environment with tall trees.

Question 4

What is the main difference between an agonist and an antagonist in relation to neurotransmitters?

Accepted Answer

An agonist enhances or mimics the action of a neurotransmitter, while an antagonist blocks it.

Question 5

Which brain region is primarily responsible for regulating basic life functions such as breathing and heart rate?

Accepted Answer

Medulla oblongata

Question 6

If a drug acts as a dopamine antagonist, what effect would it most likely have?

Accepted Answer

It would block dopamine receptors, reducing dopamine’s effects.

Question 7

Which of the following best describes the function of the adrenal gland?

Accepted Answer

It releases hormones like adrenaline during stress, preparing the body for action.

Accepted Answer

Hippocampus

Question 10

Which of the following is a real-world example of an agonist drug?

Question 11

Which equation best represents the process of natural selection?

Accepted Answer

$$Fitness = Survival \times Reproductive \ Success$$

Question 12

Which of the following best explains why the sympathetic and parasympathetic systems are considered antagonistic?

Accepted Answer

They have opposite effects on organs, balancing bodily functions.

Question 13

A person is exposed to a stressful situation. Which sequence best describes the physiological response involving the adrenal gland?

Accepted Answer

The adrenal gland releases adrenaline, increasing heart rate and energy.

Question 14

Which of the following is NOT a function of the brain’s frontal lobe?

Accepted Answer
