<span>The nervous system that controls respiration is called
autonomic because it isn't subject to voluntary control. Autonomic Nervous
System (ANS) is responsible for regulating the functions of the body's internal
organs like the heart, stomach, and intestines. It is a division of
the peripheral nervous system that acts unconsciously and it regulates
bodily functions like heart rate, digestion, and respiration. The hypothalamus
is the part of the brain that regulates the Autonomic Nervous System. Other
reflex reactions like coughing, sneezing, swallowing, and vomiting are also
part of autonomic functions that occur in the body.</span>

Answer:
The correct option is 'the ability to absorb other cells gave some prokaryotes a survival advantage.'
Explanation:
The scientists have brought forward the theory of endosymbiosis which explains how eukaryotic cells evolved from prokaryotic cells. According to this theory, the scientists claim that the organelles found today in the cells, once existed as individual prokaryotic cells. These organelles were engulfed by larger prokaryotic cells with time and hence, the eukaryotic cells evolved from these prokaryotic cells. The larger prokaryotes might have engulfed the smaller cells for survival.
The answer is capillaries.
