There are different materials of raw water, but also the raw water comes from ponds,rivers, and oceans but they might be good sometimes, and gas not been treated and has bacteria or mold buy that is not good.
Answer:
The correct answer is option b. gonadotropin-releasing hormone.
Explanation:
The GnRH or the gonadotropin-releasing hormone is a releasing hormone that releases from the neurons of the hypothalamus. This releasing hormone is responsible for the secretion of the luteinizing hormone and follicle-stimulating hormone.
GnRH regulates both gonadotropin hormones, in which, LH (luteinizing hormone) responsible for the regulation of the male reproductive system and FSH (follicle-stimulating hormone) responsible for the female reproductive system and sperm production in testes in males.
Thus, the correct answer is option B. gonadotropin-releasing hormone.
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.
