Certain drugs, such as ssris, block the reuptake of a neurotransmitter into the presynaptic cell. what effect does this have ons

Sloan [31]

Selective serotonin reuptake inhibitors (SSRIs) are drugs that are antidepressants. These blocks the reuptake of a neurotransmitter leading to increases in their activity in the synaptic cells.

<h3>What are neurotransmitters?</h3>

Neurotransmitters are defined as the signaling molecules that are secreted by the nerve cells and act as signal transporter between the neurons and the other cells of the body.

The SSRIs class of drugs affects this neurotransmitter and blocks the pathway to the presynaptic cell. This, in turn, affects synaptic communication by increasing the amount of those SSRIs in the body and acting as a stimulant to treat various diseases.

Therefore, the SSRIs block the neurotransmitter and result in their effects.

Consider a 100-gram sample of radioactive cobalt-60.

svetlana [45]

It will take 5.2 years to decay.

The half life of cobalt-60 is 5.2 years. The half life is the time taken for the mass of the substance to decrease by a half.

here, the amount of remaining substance is 50%,

so, $(\frac{1}{2} )^{n} = 0.5$

n. log (0.5) = log (0.5)

n = 1

So it would take 1 half lives to decay this much, which is 1 x 5.2 which is 5.2 years.

what do you mean by radioactive decay ?

The process through which an unstable atomic nucleus loses energy via radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A material that has unstable nuclei is considered as radioactive.

C2H5OH(g) + 302(g) → 2CO2(g) + 3H2O(g) + heat reaction type

Tcecarenko [31]

Answer:

Combustion

Explanation:

The reaction type is a combustion reaction;

Ethanol + oxygen gas → carbon dioxide + water

Now;

Ethanol is the fuel and oxygen gas rapidly combines with it to form carbon dioxide and water.

This process releases heat energy from chemical bonds.
Most hydrocarbons burn in excess air or oxygen to give carbon dioxide and water.
