Some psychologists suggest that sleep has evolved in order to allow humans to dream.

Biology
1 answer:
Kay [80]3 years ago
5 0

Answer:

True

Explanation:

Earlier it was believed by researchers that sleep is not a good thing as it does not allow an organism to stay alert all the time due to which there are high chances of such organism being consumed by other organism. However, with the discovery of theory of evolution, it is now believed that sleep has also evolved. Its evolution allows an organism to save energy and conserve it.  

Evolved sleep has helped decrease synaptic strength which allows a person to preserve memories and function well during the day time. REM sleep in the early morning makes brain metabolically active even while sleeping and hence, dream comes.

State two ways in which endocrine glands and exocrine glands differ.
denis-greek [22]

Answer:

The two major differences lies in the function and support system.

Explanation:

The two major differences between an endocrine and an exocrine system are as follows –  

a) An endocrine system releases its produce (hormones) into the connective tissue i.e blood while the exocrine system releases hormones directly into the ducts so that it could reach the targeted tissue directly.  

For example – the Adrenal gland is an endocrine gland that secretes adrenaline directly into the blood. The salivary gland is an exocrine gland that releases its produce into the collecting duct leading to mouth. However, Pancreas is both endocrine and exocrine gland.

b) The endocrine system cannot work alone therefore it works in coordination with the nervous system to control actions and balance the body. However, the exocrine system works independently
