Answer: Option B.
Absorb ultraviolet Ray's from the sun.
Explanation:
Ozone layer is the lower part of the stratosphere that absorb the ultraviolet rays of the sun. It is made up of three oxygen (O3). It is about 20 to 30 kilometers from the Earth. The ozone layer is of utmost important because it absorb the ultraviolet Ray's from the sun which can damage plants and animals. The ultraviolet rays can cause Mutation of the DNA thereby leading to death of plants and animals.
Answer: The two types of gametes are possible for when they are following genes that are on the same chromosomes. If they are crossing over, it does not occur, the products are known as Parental Gametes. If they are crossing over, the products are Recombinant Gametes. It is usually the simple matter that determine which of these gametes are recombinant gametes.
The difference between these two genes, is that are far apart and the frequency of recombination of genes is fifty percent. These genes that are closely located on the chromosome exhibit only have a few cross overs. The gametes that have recombined chromosomes, are known as Recombinant Gametes while the Parent Gametes are carrying on non-recombinant chromosomes.
