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.

The symbiotic relationship between algae and fungi is lichen.
Answer:
Blood enter the right atrium of the heart via the vena cava (superior and inferior)
The right atrium contracts to push the blood into the right ventricle through the triscupid valve
The contraction of the right ventricle pushes the blood through the pulmonary valve to the pulmonary artery which carries it to the lungs to be oxygenated
After oxygenation, the pulmonary vein brings blood to the left atrium
Contraction of the left atrium pushes the blood through the mitral valve into the left ventricle
The left ventricle contracts to push the blood through the aortic valve, into the aorta, which carries the blood through the body.
Explanation:
Answer:
there is an increase of the average global temperature due to the accumulation of polluting gases in higher atmospheric levels that causes regional and global climate change.
Explanation:
Protists are a group of organisms that are characterized as Eukaryotes that are neither plants nor animals nor fungi. They are very diverse, and there are many hypotheses about their classification. The cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. What is the implication of a changing hypothesis.
It is acceptable because data are still being collected.
It is acceptable everything in science should always change.
It is not acceptable because the correct answer needs to be found.
It is not acceptable because science never changes.
Answer:It is acceptable because data are still being collected.
