Question 5

A person is exposed to cold weather, causing their body temperature to drop. Which of the following best describes the sequence of events in the negative feedback loop that restores homeostasis?

Accepted Answer

Receptor detects change, control center processes input, effector produces response

Question 6

Which of the following best illustrates the concept of homeostatic imbalance?

Accepted Answer

Histology

Question 9

Which of the following best describes the function of serous membranes in the ventral body cavity?

Accepted Answer

They reduce friction between organs by secreting serous fluid.

Question 10

Question 15

Which of the following survival needs must be maintained within a very narrow range for proper gas exchange in the lungs?

Accepted Answer

Atmospheric pressure

Question 16

A patient has a disease that affects the connective tissue in multiple organs. At which level of structural organization is the primary problem occurring?

Accepted Answer

Tissue level

Question 17

Which of the following best explains why cartilage is found in the ear and nose, but not in bones?

Accepted Answer

Cartilage is flexible and smooth, making it ideal for structures that require flexibility.

Question 18

Accepted Answer

Movement

Question 19

Which of the following best describes the function of the control center in a homeostatic feedback loop?

Accepted Answer

It processes input from the receptor and sends output to the effector.

Question 20
