Cell membranes are made up of a phospholipid bilayer. Which part of the phospholipid bilayer interacts with water? Which part do
dimulka [17.4K]

Answer:

The polar head groups of phospholipids interact with water while the hydrophobic hydrocarbon tails are packed away from the water.

Explanation:

A phospholipid contains glycerol to which hydrocarbon tails are bonded. These hydrocarbon tails make the hydrophobic region of the phospholipids and are packed away from the water to make the inner core of the membranes. Glycerol of a phospholipid also has a phosphate group attached to its third carbon. The phosphate and glycerol moiety together make the hydrophilic head part of the phospholipid and interact with the surrounding water.

In gorillas, the ability to roll the tongue is under the control of 1 gene. The R allele, which confers tongue-rolling ability,
aalyn [17]

Answer:

0.4550

Explanation:

In this example, R allele is dominant, so individuals RR and Rr can roll their tongues. If in a population of 1000 gorillas, there are 575 gorillas who can roll their tongues, they will be RR and Rr.

In this case, there is Hardy Weinberg Equilibrium, so the following will be true:

p^{2}+2pq+q^{2}=1

Where:

p^{2}= frequency of RR

2pq= frequency of Rr

q^{2}= frequency of rr

The question is what is the frequency of heterozygotes, or, what is the value of 2pq.

We know that RR+Rr is 575 individuals in a population of 1000, or 0.575.

In other words:

p^{2}+2pq=0.575

So, it is possible to find q^{2}:

q^{2}= 1-2pq-p^{2}  \\q^{2}=1-(0.575)\\q^{2}=0.425

Now, there are two alleles in the population, so the following will be true:

p+q=1

It is possible to find q  (the frequency of allele r) and p (the frequency of allele p):

q=\sqrt{q^{2} }\\ q=\sqrt{0.425} \\q=0.652

Therefore:

p=1-q\\p=1-0.652\\p=0.348

Now, the frequency of heterozygotes or 2pq is:

2pq=2*0.652*0.348\\2pq=0.45
