Answer:
Explanation:
The above mentioned key points are mechanisms by which cells used to correct replication error and repair damaged DNA.
Proof Reading: while printing a page, the typesetter set the types and impression is taken, proof reading is done to correct mistakes if any, and the final printing is done. A similar follow up mechanism is done after DNA synthesis. If DNA polymerase detects an incorrect nucleotide pair, it will remove and replace with the correct nucleotide immediately.
Mismatch Repair:even after DNA synthesis, mismatch area(insertion or deletion) can be identified on the newly synthesized DNA.
In the mismatch repair, specific proteins scan the newly synthesized DNA strand. The mismatch area is identified and loop.
The second protein complex remove the mismatch segment. Finally correct segment is synthesized by the help of DNA polymerase, SSBs and ligase.
DNA damage repair mechanism: when DNA get damaged, there's a repair process that fix the damage. This includes Direct reversal, excision repair and Double stranded break repair
<span>Vertebrates
are known to be animals with backbones.
The following are the evolutionary changes of vertebrates:</span>
*Jaws
- Fishes before sucked and rubbed on their preys but now, they already have
jaws that enable them to more efficacious in getting their preys.
*Lungs
and limbs - Animals on the sea need to adapt when they look for their preys on
land, in turn, they had evolved to acquiring lungs for breathing and limbs for moving.
*Endothermy
- ‘Endo’ meaning internal and ‘therm’ meaning temperature. This gave animals’
bodies heat supply from burning the food they eat.

The wind chill index attempts to tell us what it "feels like" in cold, windy conditions. This index usually indicates the temperature it feels like outside to animals and people. It is also the rate of heat loss when the skin is exposed due to temperature and wind.
Answer:
A. Fishing for sea life that lives on or near the shore would be more difficult.
C. The California Grunion fish would have a hard time laying eggs.
Explanation:
The moon is an important aspect of Earth's existence. It influences the change of "ocean tides" <em>(high tide and low tide)</em>. If the moon were to suddenly disappear<em> it will present a number of problems. </em>
Firstly, the tides would<u> all remain the same</u><em> (small tides)</em>. They would also be <em>smaller </em>than the usual tide in the world today. Since the tide will be lower than usual, <u>the marine organisms will not survive living on or near the shore anymore. </u>This will make fishing for sea life in these areas more difficult.
The "California Grunion fish" normally lays its eggs along the <em>coastal areas,</em> which is <em>out of the water.</em> If the tide will be lower than usual, then they will have a hard time going to the coastlines for laying eggs.
So, this explains the answers.
