Answer:
e) Endosymbiosis.
Explanation:
According to the recent evidences, the eukaryotic cells with membrane-bound organelles originated by the process of serial endosymbiosis. According to this hypothesis, organelles such as mitochondria and chloroplasts originated when the symbiotic prokaryotes entered and lived inside other, free-living prokaryotic cells. For example, the evolution of double membrane-bound chloroplasts occurred when the photosynthetic bacteria (cyanobacteria) entered and lived inside the larger heterotrophic cells.
Likewise, the evolution of mitochondria occurred when the aerobic bacteria (most probably the purple bacteria) lived inside larger anaerobic cells. Gradually, the endosymbionts developed mutual relation with the host cells and the symbionts lost the ability to live freely outside the host cell.
They built dams which enabled them to control the flow of water and conserve water for future cases where a drought comes. So far it has been useful even though dams can be controversial because of natural habitats of animals that usually get affected.
Streptococcus pyogenes is the answer to your question.
<span> If the Brine Shrimp eggs were transported from a hyper saline lake from a less salty like, they would most likely go into their dormant state and become cyst-like since they are adapted to the salinity levels of their previous environment. In turn, they would not be able to hatch, and then later on, reproduce, in order to expand their population and continue their species. </span>
