Study the image.

which description best describes the parts of the molecule?

set a

a is the nonpolar, hydrophobic end.

b is the polar, hydrophilic end.

set b

a is the polar, hydrophilic end.

b is the nonpolar, hydrophobic end.

set c

a is the nonpolar, hydrophilic end.

b is the polar, hydrophobic end.

set d

a is the polar, hydrophobic end.

b is the nonpolar, hydrophilic end.

what set is the correct answer?

will give

The answer is; SET B

Polar molecules interact well with water because there are charged. Water molecules are partially charged (the oxygen end is partially negative while the hydrogen end is partially positive). Therefore polar molecules can interact stably with charged molecules. The hydrophobic end is non-polar and is ‘water-hating’. When mixed with water, the non-polar region clumps up  into globules so they don’t interact with water.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

the electromagnetic energy from the sun arrives in the form of visible and invisible light.
