question 8 of 10
what must be true if unicellular organisms evolved into organisms in the domain eukarya?
a. being unicellular gave a survival advantage.
b. the formation of amino acids 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 the absorption of other cells (such as the engulfment of mitochondria - like and chloroplast - like prokaryotes). This absorption provided a competitive advantage and led to the development of more complex organisms from unicellular ones. Unicellularity did not lead to the evolution into eukaryotes, amino - acid formation is not directly related to the transition from unicellular to eukaryotic organisms, and having genetic material is a basic feature of all living things and not specific to this evolutionary transition.

Answer:

C. Absorbing other cells gave a competitive advantage.
