Answer:
Point mutations are a broad category of mutations that describe a change in a single nucleotide of DNA, such as a substitution for another nucleotide, deletion of a nucleotide, or insertion of a single nucleotide into the DNA, resulting in DNA that differs from the normal or wild type gene...
or you can say:
Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the normal or wild type gene ...
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA.
Answer:
Crustaceans and Molluscs play an important role in the oceanic carbon sink.
Explanation:
Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.
- CO2 is not combustible.
- creates carbonic acid in the oceans.
- Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)
