Two biologists co-discover a population of single-celled eukaryotes that do NOT have mitochondria. Whoa! One biologist thinks th

e cells must be from a lineage that never underwent endosymbiosis, but the second biologist thinks endosymbiosis happened at some point, but the mitochondria were later lost. Which of the following provides the BEST evidence to support the second biologist?
A. the cells are incapable of surviving without sunlightB. sexual reproduction is never observedC. the nuclear genome has some genes from proteobacteriaD. the cells also contain chloroplasts

Answer: Option C

Explanation:

The amitochondriate eukaryotes may have genes that have been derived from purple alphaloproteobacteria because they do not have the mitochondria which is needed to optimize energy production in the presence of oxygen, can live and exist in a condition with little to no oxygen which is a characteristic of proteobacteria and hence are anaerobes obtaining energy by anaerobic respiration. They may have also undergone the endosymbiont theory but due to their environment which has little to no oxygen. They do not have a need for the mitochondria organelle and in the process lose this organelle.

The side chain of serine contains oxygen. water-soluble proteins often contain serine. where would the serine side chain most li
bazaltina [42]

Answer;

-On the polar end or the hydrophillic end of the protein.

Explanation;

-Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups.The R group is often referred to as the amino acid side chain.

-Side chains which have various functional groups such as acids, amides, alcohols, and Amines will impart a more polar character to the amino acid. Polar amino acids include serine, threonine, asparagine, glutamine, histidine and tyrosine.

Therefore; serine being a polar or hydrophillic  amino acid will be found on the polar side chain of the protein.
