Answer:
is a process in which deep, cold water rises toward the surface. ... Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity
Explanation:
One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C).
<h3>What are cancer cells?</h3>
Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.
When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively.
Normal cells are characterized by their ability to regulate cell division during the cell cycle.
Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.

Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
Answer:
Depending on changes, that occur with DNA, all types of DNA mutations can be divided into two main groups:
gene mutation;
chromosomal mutation.
Explanation:
Answer:
The brain cells and skin cells both contain DNA molecules, and their DNA molecules contain the same genetic information. The brain cells and skin cells both contain DNA molecules, but their DNA molecules contain different genetic information.
