Answer:
B. the hormone must enter the cell
an electrically charged particle is your answer :)
Answer: A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Explanation: I already know this for a fact.
Answer:
The correct answer would be levodopa/carbidopa.
Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.
These drugs are used to treat the symptoms of Parkinson's disease.
Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).
In the brain, levodopa is converted into dopamine which helps in controlling the movement.
Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.
Answer:
Similarity
Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.
Difference
1. nervous system uses electrical impulses (neural)for signaling while endocrine system uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.
2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.
