a) Both bacteria and humans are multicellular organisms.
b) Bacteria and humans both possess a nucleus in their cells.
c) Both bacteria and humans use DNA as their genetic material.
d) Bacteria and humans share a common ancestor in their evolutionary history.

Answer 1

Bacteria and humans both use DNA as their genetic material, which is a fundamental aspect that unites diverse forms of life and supports the concept of common ancestry in evolutionary history.

Step-by-step explanation:

You asked which sentence best describes what bacteria and humans have in common. The correct answer is c) Both bacteria and humans use DNA as their genetic material. While bacteria are single-celled and humans are multicellular, and bacteria lack a nucleus whilst human cells contain one, both organisms rely on DNA to carry and pass genetic information. This shared characteristic is a fundamental aspect of life on Earth and supports the idea that all life has a common evolutionary history.
