Classify each property of a functional group as a characteristic of the hydroxyl group (-OH), the phosphate group (-PO4)or the methyl group (-CH3)

a. used to make one end of a lipid molecule hydrophillic
b. makes attached molecule more water soluble
c. strongly charged
d. nonpolar and very stable
e. polar and forms hydrogen bonds
f. can be added to DNA to regulate gene expression

Explanation:

a. used to make one end of a lipid molecule hydrophillic - -PO4^3-

Phosphate group is Hydrophilic because it is the soluble end of the lipid and it dissociates in water.

b. makes attached molecule more water soluble - -OH

-OH reacts with water molecules readily to form hydrogen bonds.

c. strongly charged - -PO4^3-

Phosphate group has a 3- charge which means it has 3 electrons gor bonding.

d. nonpolar and very stable - -CH3

Methyl group is non polar because it does not form any hydrogen bond with water. The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed bonds -

e. polar and forms hydrogen -OH

-OH readily forms hydrogen bonds with water molecules.

f. can be added to DNA to regulate gene expression - -PO4^3-

Gene expression is very common in Eukaryotes like bacteria cells which is via phosphorylates.

b exhibiting favoritism toward the kikuyu people.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
