Question 1

Which of the following best describes the 'Structure and Function' core concept in biology?

Accepted Answer

At every level of biological organization, the structure of a biological entity gives clues to its function, and knowing the function provides insight into its structure.

Question 2

A biologist is studying the wings of bats and birds. She notices that although the wings look different, both are used for flight. Which core concept of biology is she applying?

Accepted Answer

Structure and Function

Question 3

Which of the following is NOT one of the five core concepts of biology introduced in Bio1A?

Accepted Answer

Photosynthesis

Question 4

A scientist is investigating how genetic mutations in yeast can inform our understanding of human diseases. Which core concept does this best illustrate?

Accepted Answer

Evolutionary conservation

Question 5

Which of the following best exemplifies the 'Transformation of Energy & Matter' core concept?

Accepted Answer

The process of cellular respiration converting glucose and oxygen into ATP, carbon dioxide, and water.

Question 6

Which equation best represents the law of conservation of energy as it applies to biological systems?

Accepted Answer

$$\Delta E = Q - W$$

Question 7

A student claims that biology is the study of the properties of substances and the changes they undergo. Is this statement accurate?

Accepted Answer

No, because this is the definition of chemistry, not biology.

Question 8

Which of the following best demonstrates the 'Systems' core concept in biology?

Accepted Answer

The interaction between the nervous and endocrine systems to regulate homeostasis.

Question 9

A researcher is analyzing how the expression of a gene leads to the production of a specific protein, which in turn affects an organism's phenotype. Which core concept is most directly involved?

Accepted Answer

Information Flow

Question 10

Which of the following is a key practice for thinking like a biologist, as emphasized in Bio1A?

Accepted Answer

Using evidence and being skeptical.

Question 11

Which of the following scenarios best illustrates the concept of 'Evolution' as a core concept in biology?

Accepted Answer

A population of bacteria develops resistance to an antibiotic over several generations.

Question 12

Which of the following is an example of applying the 'Structure and Function' concept to a real-world medical scenario?

Accepted Answer

Understanding how the shape of the hemoglobin protein affects its ability to carry oxygen in sickle cell anemia.

Question 13

Which of the following best describes the relationship between structure and function in biological systems?

Accepted Answer

The function of a biological structure can often be inferred from its shape and organization.

Question 14

A scientist is interested in how the breakdown of glucose provides energy for cellular processes. Which core concept is most relevant to this research?

Accepted Answer

Transformation of Energy & Matter

Question 15

Which of the following is a direct application of the 'Information Flow' concept in genetics?

Accepted Answer

Transcription of DNA to mRNA and translation to protein.

Question 16

Which of the following best illustrates the 'Systems' concept in a real-world context?

Accepted Answer

The coordinated response of the immune system to a viral infection.

Question 17

Which of the following is an example of evolutionary conservation?

Accepted Answer

A gene found in both yeast and humans that performs a similar function.

Question 18

Which of the following best describes the scientific approach emphasized in Bio1A?

Accepted Answer

Asking questions, using evidence, and being skeptical.

Question 19

Which of the following is a multi-step process that integrates both the 'Information Flow' and 'Transformation of Energy & Matter' core concepts?

Accepted Answer

The process by which a gene is transcribed and translated to produce an enzyme that catalyzes a metabolic reaction.

Question 20

Which of the following best demonstrates the importance of analyzing both structure and function in understanding a biological problem?

Accepted Answer

Studying how the three-dimensional shape of an enzyme's active site determines its specificity for a substrate.
