The sympathetic nervous system (SNS) is the division of the autonomic nervous system arouses the body and mobilizes its energy in stressful situations.
If a large animal such as a human being had a thin light exoskeleton, there would be several problems. Since the exoskeleton would not be able to hold its shape, it would be difficult to keep the vital organs protected and the organism would be subject to damaging levels of stress just by moving around. They are not strong enough to hold organs or hold its shape.
The single-celled organism in the given case is prokaryote.
A prokaryote is a unicellular species, which is devoid of a membrane-bound nucleus, mitochondria, or any other kind of membrane-bound organelle. Prokaryotes are differentiated into two domains Bacteria and Archaea.
Bacteria are prokaryotes that comprise a single cell with a basic internal composition. Bacteria are microscopic single-celled species, which live in different surroundings. Archaea are also prokaryotes, that is, devoid of the nucleus.
Archaeal cells have unique characteristics, which distinguishes them from the other two domains of life, Eukarya, and Bacteria. They are also known as extremophiles, that is, possessing the tendency to thrive in extreme environments, like salt lakes and hot springs, they are also found in a diverse range of habitats.
The benefits were more species and also more resources.<span />
