I think it may be conservation.
<span>The answer to this question would be:
- The permanent thermocline presents a barrier that keeps nutrients in deeper water from mixing with surface waters.
- The sunlight penetrates deep into the tropical ocean, warming the surface waters and creating stratification of water masses.
In tropical lands, the area is getting sunlight all around the year. This will cause the plant to be able to do photosynthesis all around the year too. Sunlight can penetrate the ocean, but the intensity will be much lower in deeper part. The ocean also become warmer but it will become cold in the deeper part too. </span>
If a scientist makes the argument that she has found DNA evidence that shows that evolution does not exist, the evidence would be the weak physical similarities among closely related organism and also among distantly related.
Germ-line mutations are mutations that would be passed down to future generations, and recombinations are where the information each parent passes down to the offspring is shuffled.
The genetic variation would have to come from random events: False
Only alternate generations would express any genetic variable: False
Body cell mutations would be the only source of heritable genetic variation: False
There would be no new heritable genetic variation possible in the population: True
