The long nephron loops of the juxtamedullary nephrons are located in the renal medulla.
<u>Explanation:</u>
The kidneys are the major filtering units that are present in the body. The kidneys filter the ions of the body and expel the waste of the body and retain the required ions in the body.
The nephrons are the functional units of the kidney that are majorly responsible for the filtering action. The longer the nephron loops are more concentrated urine is expelled from the body.

Answer:
Vesicles
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.
Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.
The neurotransmitter concentration in the vesicle interior is related to the storage system and the <u>transport system</u>. There are <u>specialized transporter proteins in the vesicle membrane</u> that are involved with the introduction of the molecule to the organelle.
In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.
DNA can illustrate that evolution has occurred since in the process of natural selection advantegeous genes or traits have been selected to pass on through generations and further more evolve as long as the species survies and is successful in reproducing.
