Question 1

Which of the following is NOT one of the unifying themes of biology emphasized in Biology 111?

Accepted Answer

Gravity

Question 2

Why are cells generally small rather than large in multicellular organisms?

Accepted Answer

Smaller cells have a higher surface area-to-volume ratio, allowing for more efficient exchange of nutrients and waste.

Question 3

Which organelle is primarily responsible for converting potential energy from food into chemical energy usable by the cell?

Accepted Answer

Mitochondrion

Question 4

A student is struggling to keep up with Biology 111 because they only study the night before exams. Based on the course advice, what is the BEST strategy to improve their performance?

Accepted Answer

Study consistently throughout the week and review material after each lecture.

Question 5

Which statement best describes the role of the plasma membrane in cells?

Accepted Answer

It surrounds the cell and creates a selectively permeable barrier to regulate transport.

Question 6

Which of the following correctly lists the levels of biological organization from smallest to largest?

Accepted Answer

Atoms, Molecules, Organelles, Cells, Tissues, Organs, Organisms, Populations, Communities, Ecosystems, Biosphere

Question 7

Which of the following is a function of ribosomes in the cell?

Accepted Answer

Synthesizing proteins from amino acids

Question 8

A multicellular organism has specialized cells for different functions. What is the main advantage of this specialization?

Accepted Answer

It allows for dedicated functions and increased efficiency within the organism.

Question 9

Which of the following statements about the nucleus in eukaryotic cells is TRUE?

Accepted Answer

The nucleus stores and protects the cell's DNA.

Question 10

Which equation best represents the relationship between surface area ($$SA) $$and volume ($$V) $$for a cube-shaped cell with side length $$l$$?

Accepted Answer

$$SA = 6l^2$, V$$ = $$l^3$$

Question 11

Which of the following is NOT a requirement for success in Biology 111 according to the course materials?

Accepted Answer

Waiting until the last minute to study for exams

Question 12

Which of the following is a real-world application of understanding cell structure and function?

Accepted Answer

Developing targeted medical treatments that affect specific organelles

Question 13

Which of the following statements about prokaryotic and eukaryotic cells is correct?

Accepted Answer

Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.

Question 14

Which of the following molecules is NOT a major component of organelles?

Accepted Answer

Question 15

Which of the following best explains why understanding how atoms interact to form molecules is essential in biology?

Accepted Answer

It helps explain cellular structure and function at the molecular level.

Question 16

Which of the following is a correct statement about evolution according to the course materials?

Accepted Answer

Evolution accounts for both the unity and diversity of life.

Question 17

A cell is observed to have a nucleus, mitochondria, and a plasma membrane. Which type of cell is this most likely to be?

Accepted Answer

Eukaryotic cell

Question 18

Which of the following is the most basic unit of life?

Accepted Answer

Cell

Question 19

Which of the following is a plausible consequence if a cell's plasma membrane loses its selective permeability?

Accepted Answer

The cell may be unable to regulate the movement of substances, leading to loss of homeostasis.

Question 20

Which of the following best describes the scientific study of life?

Accepted Answer
