Question 1

Which of the following is NOT one of the seven characteristics of life described in the lecture?

Accepted Answer

Ability to photosynthesize

Question 2

Darwin’s journey on the HMS Beagle contributed most directly to which foundational concept in biology?

Accepted Answer

Theory of evolution by natural selection

Question 3

Which statement best describes the difference between artificial selection and natural selection?

Accepted Answer

Artificial selection is driven by human choice, while natural selection is driven by environmental factors.

Question 4

A scientist wants to test the effect of light on plant growth. She keeps one group of plants in the dark and another in the light, measuring their growth over time. In this experiment, what is the variable?

Accepted Answer

The exposure to light

Question 5

Which reasoning process involves using specific observations to construct general scientific principles?

Accepted Answer

Inductive reasoning

Question 6

Which of the following best explains why living systems require a constant input of energy?

Accepted Answer

To maintain homeostasis and prevent entropy

Question 7

In a controlled experiment testing the germ hypothesis, which prediction would support the hypothesis?

Accepted Answer

Sterilized broth will remain sterile if microbes are prevented from entering.

Question 8

Which of the following is a limitation of the reductionist approach when applied to living systems?

Accepted Answer

It ignores the complex interworking of many interconnected functions, making emergent properties difficult to predict.

Question 9

Which of the following statements about scientific theories is TRUE from a scientist’s perspective?

Accepted Answer

A theory is a body of interconnected concepts supported by scientific reasoning and experimental evidence.

Question 10

Which mechanism of evolutionary change involves random changes in allele frequencies in a population?

Accepted Answer

Genetic drift

Question 11

Why do biologists say that 'structure determines function'?

Accepted Answer

Because the function of molecules, cells, tissues, and organs depends on their structure.

Question 12

Which of the following is a real-world example of evolutionary adaptation?

Accepted Answer

A population of bacteria developing resistance to antibiotics over several generations.

Question 13

Which of the following best describes the role of DNA in living systems?

Accepted Answer

DNA is the molecule of heredity, allowing information to be passed generationally.

Question 14

A student claims that individuals evolve over their lifetime. Based on evolutionary theory, how should you respond?

Accepted Answer

Individuals do not evolve; populations evolve over time.

Question 15

Which of the following is an example of inductive reasoning in biology?

Accepted Answer

Using observations of finch beak shapes to propose a general principle about adaptation.

Question 16

Which of the following is NOT a requirement for maintaining homeostasis in living organisms?

Accepted Answer

Allowing internal conditions to fluctuate wildly

Question 17

Which equation best represents the transformation of energy in living systems?

Accepted Answer

$$	ext{Chemical energy} ightarrow 	ext{ATP} ightarrow 	ext{Work} + 	ext{Heat}$$

Question 18

Which of the following is a correct application of the scientific method in biology?

Accepted Answer

Formulating a hypothesis, making predictions, and testing them through controlled experiments.

Question 19

Which of the following best explains why much of biology is descriptive?

Accepted Answer

Accurate description is the first step in understanding biological phenomena.
