Biology
1 answer:
Cloud [144]3 years ago
5 0

Answer:

Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.

Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.

The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.

What is not one of the roles of the parasympathetic nervous system?
Anvisha [2.4K]

Complete question:

Question: What is not one of the roles of the parasympathetic nervous system?

a) increases digestive functions

b) maintains resting heart rate

c) stimulating urination

d) controls the diameter of blood vessels

Answer:

d) controls the diameter of blood vessels

Explanation:

The activated parasympathetic nervous system is mainly associated with the rest and digest activities. This division of the autonomic nervous system triggers the digestive glands to release their secretions and stimulate the contractions of smooth muscles of the digestive tract to upregulate the processes of digestion and absorption of nutrients. In this way, the parasympathetic nervous system restores and conserves the energy of the body. It has no effect on the diameter of blood vessels.

The sympathetic nervous system triggers constriction of blood vessels that supply blood to kidneys and digestive tract during emergency conditions. It also dilates the blood vessels that supply blood to skeletal muscles, cardiac muscles and liver to facilitate increased blood supply to these tissues.

What are some fun facts on animal and plant cells.
ArbitrLikvidat [17]
Animal cells:
They are self sufficient, because of Nano-Chemical factories, so they can make their own stuff like cell membranes.
A cell can destroy itself through apoptosis in the event that it is irreparable.

Plant cells:
These were the first type of cells discovered by us.
Plants only actually use about 1/6 of the energy they get from photosynthesis, the rest is stored for animals that eat the plant.<span />
