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.

Hi there!
I think bread turns moldy less quickly when it is kept in a refrigerator than when it is kept at room temperature because bacteria eats foods like bread and causes mold, and less bacteria grow in colder temperatures. Since less types of bacteria thrive in colder temperatures, it takes longer for less bacteria to create mold.
Hope this helps!
Answer:
miR-223 inhibits the expression of the fibroblast growth factor (bFGF) gene, and thereby ESCs cells maintain their undifferentiated state
.
Explanation:
Non-coding RNA (ncRNAs) are molecules that regulate gene expression, thereby playing important biological functions in cell differentiation, cell cycle, apoptosis, etc. MicroRNAs (miRNAs) are a type of ncRNAs capable of controlling gene expression patterns by regulating mRNA stability and by suppressing their translation into proteins. It has been shown that miRNAs function by imperfectly base-pairing with the 3′ UTR of target mRNAs (Pillai et al. 2005).
