Answer:

The correct answer is - reuptake of the neurotransmitter molecule into the axon through a membrane transporter.

Explanation:

The action of a neurotransmitter at the postsynaptic cell or postsynaptic potentials is terminated by any of these mechanisms that are enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.

After the desired biological response by postsynaptic potentials, in order to avoid over stimulation or termination of the postsynaptic potentials the neurotransmitter is taken back into the axon through a membrane transporter. This mechanism is to maintain a balance.

Why are decomposers and detritivores essential parts of all food webs?
Vinil7 [7]

Answer: Detritivores improve the nutritional value and the texture of the soil: This makes the soil productive to plant life which translates to availability of food for the herbivores and carnivores like human beings. They however do not complete the energy cycle as their wastes are energy products that need to be decayed.

Decomposers help in converting the leftovers of animals and plants to useful substances for other living organisms. They are mainly bacteria and fungi. Have you ever wondered what would happen if the decomposers and consumers were not in the ecosystem?

Detritivores play a very important in the cycle as they are the consumers of dead leaves, old skin, carcasses and manure. They include millipedes, earthworms and slugs that feed on dead plants and animals but leave some parts and their feces that are converted to energy by the decomposers. Players in the energy cycle function hand in hand, a decomposer is found at the lowest part of the cycle as it deals with the remains. They complete the energy cycle. The roles of the decomposers and detritivores almost coincide.

Hope this helps !!! Good luck !!! ;)

What period(s) show the most rapid increase in adipose tissue?
Sergio [31]

Answer:

a and b

Explanation:

The growth of adipose tissue in newborns is directly linked to the fact that they do not have proper body temperature control, so fat acts as a thermal insulator in order to maintain a constant temperature, also, breast milk density can also influence baby fat gain.

For the first six months the baby still has a lot of fluid retention and so it may give the impression that he is getting fatter, but after the first six months until the end of the first year, the baby tends to lose this fluid, decreasing on average 10% of body weight.

<u>Girls</u> in adolescence and pre-adolescence have a tendency to gain weight due to the enormous hormonal load they receive at puberty, as well as other factors such as poor diet.

The same does not happen as often in <u>boys</u> because a good part tends to have a "leap" growth in puberty, favoring weight loss. The process of fattening in teenage boys is more associated with sedentary practices and consumption of junk food.

If a triglyceride that contains one palmitate and two linoleate groups is completely hydrolyzed in the presence of a lipase enzy
34kurt

Answer:

The reaction will yield 3 molecules.

  1. Glycerol
  2. Linoleic acid
  3. Palmitic acid

Explanation:

I have attached a picture containing triglyceride molecule (Same as described in question). When metabolism of this molecule occur it will be converted into 3 products (Picture of chemical reaction is attached). Triglyceride will release its backbone as glycerol molecule along with Linoleic acid and Palmitic acid. In this reaction 1 molecule of water will be utilized. Thus no molecule of water will be released.
