Question 3

A researcher is studying how the introduction of a new predator affects the population sizes of several species in a forest and the nutrient cycling in the soil. This approach is best described as:

Accepted Answer

Systems biology

Question 4

Which of the following is NOT an example of the relationship between structure and function?

Accepted Answer

Cells in the intestinal lining have few projections for absorption.

Question 5

Which of the following best describes the scientific process?

Accepted Answer

A cyclical process involving exploration, hypothesis formation, testing, and community feedback.

Question 6

Dr. Allison’s malaria research involved collecting both numerical data on infection rates and descriptive observations about symptoms. What type of data did he collect?

Accepted Answer

Both qualitative and quantitative data

Question 7

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

Accepted Answer

Predicting that all mammals have hair because you know that dogs and cats have hair.

Question 8

A scientist observes that sickle cell trait is common in regions with high malaria incidence and hypothesizes that the trait confers resistance to malaria. This hypothesis is an example of:

Accepted Answer

Inductive reasoning

Question 9

Which of the following best describes reductionism in biological research?

Accepted Answer

Breaking down complex systems into simpler components for study.

Question 10

Which of the following is a real-world example of a systems biology question?

Accepted Answer

How does the introduction of a new plant species affect the entire ecosystem, including herbivores and decomposers?

Question 11

Which of the following is an emergent property that cannot be predicted by studying individual components alone?

Accepted Answer

The coordinated behavior of an ant colony.

Question 12

A student wants to test whether a new fertilizer increases plant growth. Which step should come first in the scientific process?

Accepted Answer

Making observations about plant growth

Question 13

Which of the following best describes quantitative data?

Accepted Answer

Numerical measurements such as height or weight

Question 14

Which of the following is an example of deductive reasoning?

Accepted Answer

All birds have feathers. A sparrow is a bird. Therefore, a sparrow has feathers.

Question 15

Which of the following is NOT a step in the scientific process as described in the study materials?

Accepted Answer

Ignoring community analysis and feedback

Question 16

Why do mitochondria have many inner membrane infoldings (cristae)?

Accepted Answer

To increase the surface area for ATP production

Question 17

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

Accepted Answer

The structure of a biological component determines its function.

Accepted Answer

Reductionism

Question 19

Which of the following is a correct sequence of levels of biological organization from smallest to largest?

Accepted Answer
