Why doesn't a skin cell make crystallin protein? select all that apply. select all that apply. skin cells use different dna for their genes. skin cells have the crystallin gene but do not express it. skin cells do not need crystallin for their function. the crystallin gene is not present in skin cells?

Answer;

-Skin cells do not need crystallin for their function.

-Skin cells have the crystallin gene but do not express it.

Explanation;

-The crystallin proteins are water-soluble structural proteins that occur in high concentration in the cytoplasm of eye lens fibre cells. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors.

-The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. The skin cell does not make crystallin protein because the skin cells do not need crystallin for their function and also they have the crystallin gene but do not express it.

Skin cells have the crystallin gene but do not express it.

Skin cells do not need crystallin for their function.

Explanation:

I did the assignment on Master Biology (for the AP BIO course) lmk if it is wrong so I can remove my answer. :)

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
