Q: Which equation best represents the concept of metabolism in living cells?

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

Question 1

Which of the following is NOT a characteristic that distinguishes living organisms from non-living things?

Accepted Answer

Living organisms are always multicellular.

Question 2

A scientist discovers a new organism that is able to grow, respond to stimuli, and reproduce, but is not composed of cells. According to the characteristics of life, how should this organism be classified?

Accepted Answer

It is not a living organism because it is not composed of cells.

Question 3

Which of the following molecules is NOT one of the four major types found in living organisms?

Accepted Answer

Silicates

Question 4

Homeostasis is best described as:

Accepted Answer

A state of internal equilibrium maintained by living organisms.

Question 5

Which of the following is an example of a living organism responding to its external environment?

Accepted Answer

A plant leaf turning to face the sun.

Question 6

Which equation best represents the concept of metabolism in living cells?

Accepted Answer

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

Question 7

A population of bacteria exposed to a $$\beta-$$lactam antibiotic develops resistance over time. This is an example of which characteristic of life?

Accepted Answer

Evolution

Question 8

Which domain includes organisms that are eukaryotic and can be multicellular, photosynthetic, or heterotrophic?

Accepted Answer

Eukarya

Question 9

Which of the following is a defining feature of humans compared to other primates?

Accepted Answer

Opposable thumbs and complex language

Question 10

If a scientist finds a fossil with a pelvis adapted for upright walking and a large braincase, which classification is most likely supported?

Accepted Answer

The fossil is closely related to Homo sapiens.

Question 11

Which of the following best explains why mountains and glaciers are not considered living organisms, even though they can increase in size?

Accepted Answer

They do not reproduce or are composed of cells.

Question 12

Which kingdom within the domain Eukarya contains organisms that are primarily decomposers?

Accepted Answer

Kingdom Fungi

Question 13

Which of the following is an example of homeostasis in humans?

Accepted Answer

Sweating to cool the body during exercise.

Question 14

Which of the following is the correct hierarchical classification for humans, from domain to species?

Accepted Answer

Eukarya, Animalia, Chordata, Mammalia, Primates, Hominidae, Homo sapiens

Question 15

Which of the following best describes the role of raw materials in metabolism?

Accepted Answer

Raw materials are used as reactants in cellular chemical reactions.

Question 16

A population of bacteria exposed to antibiotics develops resistance due to a change in the structure of the $$\beta-$$lactam ring. What biological process does this illustrate?

Accepted Answer

Evolution through natural selection.

Question 17

Which of the following is a correct statement about cells?

Accepted Answer

Cells are the smallest units that show all the characteristics of life.

Question 18

Which of the following is NOT a function of metabolism in living organisms?

Accepted Answer

Forming mountains through tectonic activity.

Question 19

Which of the following best describes the relationship between energy and metabolism in living organisms?

Accepted Answer

Energy is required to drive the chemical reactions that make up metabolism.

Question 20

Which of the following is a real-world example of evolution in a population?

Accepted Answer
