Question 21 • Anatomy & Physiology A

Which of the following correctly lists the characteristics that all living things share?

Answer
A
Living things are made of proteins, contain genes, replicate, have a metabolism, grow, and have a limited lifespan.
B
Living things are made of proteins, contain genes, reproduce, offer feedback, have a metabolism, grow, and have a limited lifespan.
C
Living things are made of cells, contain genes, reproduce, offer feedback, have a metabolism, grow, and have a limited lifespan.
D
Living things are made of cells, contain genes, replicate, have a metabolism, grow, and have a limited lifespan.

Explanation

All living things are made of cells and contain genetic information. They reproduce, respond to changes in their environment (offer feedback), carry out metabolism, grow, and have a limited lifespan. Choices A and B incorrectly say living things are made of proteins, while D says they replicate rather than reproduce and leaves out responding to the environment.
