Answer:

Answer B. Endosymbiosis

Explanation:

Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.

Revise this sentence by replacing all gerunds with infinitives.
vekshin1

Answer:

Please see below

Explanation:

I always tell people that I love to dance, to write and to paint.

The verb keep cannot take an infinitive afterwards so it is better to replace that expression  altogether with another one that means the same thing, but that can use an infinitive. The verb love can take either gerunds or infinitives afterwards with only a subtle variation in the meaning.
