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.
1. They play dead when faced by a predator.
2. They travel in schools of about 12.
3. Males establish their dominance by having sword fights with their spines and showing off their bright colors.
The answer is B because convection is the transfer of heat without two objects touching.
