Question 4

Which of the following best describes an emergent property in a biological system?

Accepted Answer

A property that arises only when individual components interact in a system

Question 5

Accepted Answer

Eukaryotic cells have a nucleus, while prokaryotic cells do not

Question 9

What does DNA stand for, and why is it essential for life?

Accepted Answer

Quantitative data

Question 17

In the mouse coat coloration experiment, what was the dependent variable?

Accepted Answer

The survival rate of mice in different environments

Question 18

What is the purpose of using a control group in an experiment?

Accepted Answer

To provide a baseline for comparison and isolate the effect of the independent variable

Question 19

Question 20

Which statement best distinguishes a scientific theory from a hypothesis?

Accepted Answer
