Explanation:

The quantity of energy decreases down each trophic level as only 10% of the energy at the upper level is transferred to the next level, the remaining 90% is lost as heat during metabolic process. Through the energy pyramid we can explain how energy is lost at each trophic level, the number of consumer at each trophic level that will benefit from the transfer of energy depends on the size and quality of the energy from the autotrophs

natta225 [31]

According to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.

<h3>What are Experiments?</h3>

It is the process by which one or more variables are intentionally manipulated by carrying out actions aimed at discovering or verifying certain phenomena.

In this sense, its basis is in the manipulation of the variables that are considered relevant, the control of strange variables and the randomization of the rest.

Therefore, we can conclude that according to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.

Elan Coil [88]

Answer:

Option-D

Explanation:

Parkinson's diseases are a neural disorder which affects the movement of the human body. The disease is caused by the low production or no production of dopamine by the neurons which thus interfere with the impulse transfer and thus movement.

In the given question, the patient with Parkinson's disease is provided with levodopa but no improvement is observed therefore the prescriber must change the drug regimen, for example, the levodopa should be given in combination with carbidopa. These medications enter the blood-brain barrier and get converted to the dopamine.

Thus, Option-D is the correct answer.

aalyn [17]

Answer:

Gamma-aminobutyric acid (GABA)

Explanation:

Gamma-aminobutyric acid (GABA) is the inhibitory neurotransmitter found in the central nervous system of mammals, especially humans, which is responsible for the regulation of communication between the brain cells, and also implicated in the slowing down of signals as neuronal impulses is reduced when it is activated. This is mostly responsible for the extreme uninhibited behaviors often associated with large alcohol consumption.
