Question

question 9 of 10
what must be true if unicellular organisms evolved into organisms in the
domain eukarya?
a. the formation of amino acids gave a survival advantage.
b. being unicellular gave a survival advantage.
c. absorbing other cells gave a competitive advantage.
d. having genetic material gave a survival advantage.

Explanation:

The endosymbiotic theory suggests that eukaryotic cells evolved from unicellular organisms absorbing other cells (like mitochondria and chloroplasts from prokaryotes). This absorption provided a competitive advantage, leading to the development of more complex eukaryotic cells. Amino acids (A) are basic building blocks but not directly related to this evolution. Being unicellular (B) would not explain the evolution into eukaryotes (which can be multicellular). All cells (including prokaryotes) have genetic material (D), so it doesn't specifically explain the evolution to eukaryotes.

Answer:

C. Absorbing other cells gave a competitive advantage.
