Imagine a new type of cell was discovered on mars in an organism growing in benzene, a nonpolar liquid. the cell had a lipid bilayer made of phospholipids, but its structure was very different from that of our cell membranes. what might be characteristic features of the phospholipid head groups? 1) the phospholipid head groups would likely bind to each other with covalent bonds that would pack well and not be bulky.2) the phospholipid head groups would likely have equal numbers of positively and negatively charged groups that would pack well and not be bulky.3) the phospholipid head groups would likely have equal numbers of hydroxyl and amino groups that would pack well and not be bulky.4) the phospholipid head groups would likely bind to each other with hydrogen bonding that would pack well and not be bulky.

In a relatively small iguana population the allelic frequency is tracked for three generations. webbing is a recessive allele; no webbing is the dominant allele. during one very rainy spring and summer, a flood washes all the iguana without webbed feet out to sea. by the fall, and three generations later, you have the gene pool seen here.
