Which group of organisms can display the most significant adaptations to their environment in the shortest period of time? A. Bacteria
B. Fish
C. Insects
D. Mammals

A. Bacteria

Explanation:

Displayed by how rapidly antibiotic resistance can develop, bacteria are the organisms that can make the quickest, significant adaptations.

Bacteria also reproduce by binary fission, where one bacteria becomes two.

This method of reproduction occurs rapidly, meaning that bacteria grow exponentially, as each bacteria will double. Over time, this will create a huge population.

This ability to reproduce quickly into a large population means that there is a greater chance for diverse mutations to appear. Some of these mutations will be helpful, and allow the bacteria to survive and reproduce when there are changes to their environments.

These mutations will lead to quick adaptations to the environment.

So, the correct answer is A. Bacteria
