Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.

Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :
1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing
2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing.
They are both light resources.
