Question 5

Which of the following statements correctly distinguishes prokaryotic from eukaryotic cells?

It serves as a negative control to compare against the antibiotic treatment.

Question 20

Which of the following best explains how evolution accounts for both the unity and diversity of life?

Accepted Answer

Evolution results in species adapting to different environments, leading to diversity, while common ancestry explains unity.
