Question 3

A scientist is studying the effect of temperature on the rate of photosynthesis in plants. In this experiment, what is the independent variable?

Accepted Answer

The temperature

Question 4

Which of the following statements about negative feedback is correct?

Accepted Answer

Negative feedback reduces the initial stimulus to maintain homeostasis.

Question 5

In the case study of the beach and inland mice, what was the main hypothesis tested by Hopi Hoekstra and colleagues?

Accepted Answer

Mice that do not match their habitat are preyed on more heavily than those that do.

Question 6

Which of the following best explains why energy flow in an ecosystem is not cyclic, while chemical cycling is?

Accepted Answer

Energy enters as light and exits as heat, while chemicals are reused and recycled.

Question 7

Which of the following is NOT a unifying theme of biology?

Accepted Answer

Gravity

Question 8

Accepted Answer

A broad explanation supported by a large body of evidence.

Question 9

Which of the following is an example of homeostasis?

Accepted Answer

A human shivering to maintain body temperature.

Question 10

Which of the following best describes the relationship between science and technology?

Accepted Answer

Technology is the application of scientific knowledge for a specific purpose.

Question 11

Which of the following is a property of life that involves the transmission of genetic information?

Accepted Answer

Reproduction

Question 12

In a controlled experiment, what is the purpose of the control group?

Accepted Answer

To provide a baseline for comparison with the experimental group.

Question 13

Which of the following best illustrates the concept of reductionism?

Accepted Answer

Breaking down complex biological systems into simpler components for study.

Question 14

Which of the following is an example of positive feedback in biological systems?

Accepted Answer

The process of blood clotting, where the end product speeds up its own production.

Question 15

Which of the following statements about genes is correct?

Accepted Answer

Genes are the units of inheritance and encode information for building molecules within the cell.

Question 16

Accepted Answer

The growth of the plants

Question 17

Which of the following best describes the role of producers in an ecosystem?

Accepted Answer

They convert light energy into chemical energy through photosynthesis.

Question 18

Why is statistical analysis important in scientific experiments?

Accepted Answer

It tests whether the results are statistically significant and not due to chance.

Question 19

Which of the following is an example of how science benefits from diverse viewpoints?

Accepted Answer
