Answer:
Over 95% of incoming ultraviolet radiation is absorbed in :
A. The Stratosphere.
Explanation:
- Stratosphere is the second layer of the earth's atmosphere that lies next to the troposphere.
- This layer experiences very little turbulence of air and is very significant because of the presence of Ozone layer in it.
- The UV rays entering the Earth's atmosphere, photo dissociates ozone into O₂ and O. But these molecules quickly recombine to form ozone.Thus, stabilizing the concentration of ozone in the atmosphere.
- During this photo dissociation UV radiations loses much of its energy. Thus, 95% of incoming Ultraviolet radiation gets absorbed in the Stratosphere.
- Absorption of ozone UV radiation increases exponentially with the thickness of ozone layer.
Answer:
well the 1 or 3 is my guess
Explanation:
The 1 is my main answer but 3 is a possibilty i suppose
Answer:
Explanation:
DNA polymerases are the enzymes that build DNA in cells. DNA polymerase also proofread their work to check for any error the process of which is called proof reading.
If the polymerase detects that an Incorrectly paired nucleotide has been added, it will remove (splicing) and replace the nucleotide with the correct one before it continues with DNA synthesis.
Mismatch repairing also corrects other errors that omit proofreading. They fix mismatched base pairs, replace some insertion and deleted base pair that can result into mutations.
When an error is corrected the rate of mutation is reduced this is because mutation results from error during the DNA formation process either through Insertion of a wrong nitrogenous base, or deletion leading to formation of an entirely new amino acid sequence that result into abnormal phenotype.
If two recessive alleles are present the Recessive trait will be expressed.
