Q: Which of the following equations best represents the relationship between anabolism and catabolism in metabolism?

$\text{Metabolism} = \text{Anabolism} + \text{Catabolism}$

Question 1

Which of the following best describes the principle of complementarity of structure and function in human anatomy?

Accepted Answer

Form follows function, meaning that the structure of a body part is directly related to its function.

Accepted Answer

Negative feedback loop to decrease body temperature.

Question 3

Which organ system is primarily responsible for producing movement and generating heat in the human body?

Accepted Answer

Muscular system

Question 4

Which of the following is NOT a characteristic of living organisms?

Accepted Answer

Photosynthesis

Question 5

A blood vessel is injured and platelets begin to accumulate at the site, releasing chemicals that attract more platelets. What type of feedback loop is this an example of?

Accepted Answer

Positive feedback loop

Question 6

Which level of structural organization is defined as a group of similar cells and their extracellular matrix performing a common function?

Accepted Answer

Tissue level

Question 7

If a person’s blood glucose rises after a meal, which organ system is primarily responsible for releasing hormones to lower it back to normal?

Accepted Answer

Endocrine system

Question 8

Which of the following statements about homeostasis is TRUE?

Accepted Answer

Homeostasis involves maintaining variables near a set point through feedback loops.

Question 9

Which organ system is responsible for returning excess fluid to the cardiovascular system and providing immunity?

Accepted Answer

Lymphatic system

Question 10

A gradient exists when:

Accepted Answer

More of something is present in one area than another and the areas are connected.

Question 11

Which of the following is an example of cell-to-cell communication in the human body?

Accepted Answer

A nerve cell releases chemical messengers that stimulate a muscle cell to contract.

Question 12

Which organ system regulates body functions through hormones?

Accepted Answer

Endocrine system

Question 13

Which of the following best illustrates the relationship between structure and function?

Accepted Answer

Thin tissues inside the lungs permit gas exchange.

Question 14

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

Accepted Answer

Regulation of body temperature

Question 15

Which organ system includes the kidneys, ureters, urinary bladder, and urethra?

Accepted Answer

Urinary system

Question 16

Which of the following is TRUE regarding positive feedback loops?

Accepted Answer

They reinforce the initial stimulus and increase the output.

Question 17

During childbirth, uterine contractions cause the baby to stretch the uterus more, leading to stronger contractions. This is an example of:

Accepted Answer

Positive feedback

Question 18

Which of the following equations best represents the relationship between anabolism and catabolism in metabolism?

Accepted Answer

$	ext{Metabolism} = 	ext{Anabolism} + 	ext{Catabolism}$

Question 19

If a cell increases in size and number due to anabolic reactions exceeding catabolic reactions, which characteristic of living organisms is being demonstrated?

Accepted Answer

Growth
