AURORKA [14]

Answer:

Part A....B

Part B....C

Explanation:

It should be understood that Mice are always first used to clinical test especially for drugs or other things that are supposed to be for human use, this is because Mice and human genetic disorders have arisen from conserved and related evolutionary processes. Therefore, when the clinical trial or test produces a positive result in the Mice, it is almost certain that the result will be the same in human.

Now in part B. When the result result is different, it might be because of the differences in anatomy and physiology might hide or change development and symptoms of disease. And that is the reason why, the result of a particular drug differs from person to person.

MrRa [10]

Answer:

The correct answer is eukaryotes engulfed photosynthesizing prokaryotes

Explanation:

The endosymbiotic theory or symbiogenesis is an evolutionary theory that traces the origin of eukaryotic cells from prokaryotic organisms. It explains that some of the organelles (Mitochondria and Chloroplasts) in eukaryotic cells evolved from free-living prokaryotic microbes which were ingested or engulfed. The ingested prokaryotic cells survived within the organism and developed a symbiotic relationship.

According to the theory, chloroplasts was formed when eukaryotes engulfed photosynthesizing prokaryotes and mitochondria was formed when bacteria capable of aerobic respiration were engulfed.
