Which of the following describes why phospholipids are better suited to forming the cell membrane than regular fats or steroids?

a. their glycerol head allows them to bond easily with most other molecules.
b. their phosphate group gives them a hydrophilic end.
c. their three-pronged structure allows them to store large amounts of energy.
d. their unique ringed structure provides them with the ability to regulate cell metabolism.

idk this one.. maybe b? ?

The correct answer would be B. Their phosphate group gives them a hydrophilic end.

The phosphate group in phospholipid is responsible for the amphiphilic nature of the phospholipid bilayer.

The phosphate group forms the hydrophilic end whereas the lipid chain forms the hydrophobic end.

The hydrophilic end enables the plasma membrane to interact with the substances inside and outside the cell.

It also provides the cell membrane its semi-permeable nature.

It provides stability to the membrane proteins present in the plasma membrane.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
