The effect nervous system has on the heart rate is
Stimulation by parasympathetic nerves causes the heart rate to slow down.
The two branches of the autonomic (involuntary) nervous system regulate heart rate. The parasympathetic nervous system and the sympathetic nervous system (SNS and PNS) (PNS). To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The hormone acetylcholine is released by the parasympathetic nervous system (PNS) to reduce the heart rate. Your heart rate may briefly increase due to stress, coffee, and excitement, whereas it may temporarily decrease due to meditation or deep, steady breathing. Any amount of exercise will raise your heart rate, which will stay up as long as you keep exercising.

The correct answer is multiple sclerosis.
The MS or multiple sclerosis refers to a demyelinating disorder in which the insulating envelopes of the nervous tissues in the spinal cord and the brain get destructed.
This destruction disturbs the tendency of the components of the nervous system to interact, leading to an array of symptoms and signs, involving mental, physical, and on certain occasions psychiatric issues.
There are thought to be between 60,000 and 200,000 protist species, and many have yet to be identified. Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems.
Fishes use the coral reef for shelter during the day as well as food.

Information related to coral reef</h3>
One way that fish interact with a coral reef is that fish hide within the coral. Coral reefs are an important resource for large-bodied fish in the Caribbean. They use the reef for shelter during the day.
Coral reefs are important ecosystems because coral reefs contain a great diversity of life. The color of coral depends on the type of polyp present. Coral polyps are tiny little animals that can live individually, or in large colonies that comprise a coral reef.
Great Barrier Reef is considered as the largest coral reef on Earth. Coastal land development, silt runoff, water pollution by humans, damage from scuba diving, boating, and fishing are the threats to the health of coral reef.
