The answer is commensalism. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism is when both partners benefit. Commensalism is when only one species benefits while the other is neither helped nor harmed. Lastly, Parasitism is when one organism (the parasite) gains, while the other (the host) suffers.

Answer:
As skin cells move toward the surface of the body, they produce a protein that reduces water loss. This process is called Keratinization.
Explanation:
Keratinization is a process which changes the stratum corneum of the skin to a hard cover which provides protection.
The process of keratinization involves polymerization of keratin polypeptides. The keratin polypeptides gets polymerized into intermediate filaments of keratin. Each of the intermediate filament of keratin constitute around 30,000 polypeptides of keratin.

Explanation:
Answer:
The change in conformation of voltage-gated calcium channels in the axon terminal membrane causes the increase in cytosolic calcium that triggers the fusion of secretory vesicles to the membrane and the release of neurotransmitters into the synaptic cleft.
Explanation:
- As the calcium concentration becomes less in the cytosol, it allows calcium ions and functions it as a secondary messenger in the calcium signaling process.
- During the action potential, or any nerve impulse, that arrives at the terminal of axon, the activation of voltage-gated calcium channel is carried. This activation is done in the cell membrane.
- Calcium ion has the key responsibility for the triggering of synaptic vesicles to release the neurotransmitters.
