C. reinhardtii is a species of unicellular green algae that primarily produce energy for
growth through photosynthesis. However, when necessary, they can also produce
energy from a carbon source, which allows them to grow in total darkness. A scientist
grows a population of this algae in the dark and finds that after 600 generations, the
algae population now grows better in the dark than in the light.
Which statement best explains what has happened to the cells in the algae population?
Select one:
O a. The cells that were better adapted to growing in the dark reproduced more.
O b. The cells that were better adapted to growing in the light got smaller in size.
Oc. They became contaminated with a species of algae that grow only in the dark.
Od. They evolved into a different species that can grow only in the dark.



Answer :

Final answer:

In a dark environment, cells better adapted to darkness reproduce more, showcasing natural selection's role in adaptation.


Explanation:

The cells that were better adapted to growing in the dark reproduced more. This phenomenon is an example of natural selection, where the traits that are advantageous in a particular environment are favored and passed down to future generations. Over time, the population shifts towards individuals with characteristics that enhance survival and reproduction in the dark.
