Glycerophospholipids have heads and long fatty acid tails.

A) polar; polar
B) polar; hydrophobic
C) hydrophobic; polar
D) hydrophobic; hydrophobic

Polar; hydrophobic (Ans. B)

Explanation:

Glycerophospholipids are known as the class of lipids which are found extensively in the biological membrane. They are usually consisting two regions of lipids which provide structure to the lipid bilayer in which the hydrophilic heads (polar) attaching outside to the cell and the hydrophobic tails (non-polar) pointing insides to the cell membrane.

Glycerophospholipids helps to provide permeability and fluidity to the membrane and also helps in the programmed cell death, and modulation of actions of membrane-bound enzymes.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
