What must be true if prokaryotes evolved into eukaryotes by endosymbiosis? a. the formation of amino acids gave a survival advantage. b. the ability to absorb other cells gave some prokaryotes a survival advantage. c. having genetic material gave a survival advantage. d. being unicellular gave a survival advantage.

B

Explanation:

The evolution of eukaryotic cells is explained by the endosymbiotic theory i.e. when large cells engulfed smaller cells in a process called phagocytosis. The theory further explained that these engulfed small cells were not broken down but instead lived as organelles in the large cells forming a symbiotic relationship.

Since the endosymbiotic theory of eukaryotes evolution is simply based on the engulfing of one cell, hence, the absorbing ability is the survival advantage.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

i wish i could with all of them i can barley see the first one so here's the answer to the first one b
