All plants and animals are made up of cells where the genetic material can be found in the form of genes and chromosomes (usually in the nucleus).
The punnet square gives the frequency with which each phenotype is observed. In this case, the possible outcomes are 9 + 3 + 3 + 1 = 16, 9 members will have one phenotype, three members will have a second phenotype, three members will have a third phenotype and 1 individual will have a fourth phenotype.
The mesosphere extends upward above the stratosphere, temperatures decrease. The coldest parts of our atmosphere are located in this layer and can reach –90°C.
The Genetic Variation, Mutagens produce the greatest variety. This category includes radiation (UV light, Xrays), chemical, etc. <span>They change DNA/RNA, thereby increasing the number of mutations, which in turn, leads to producing the greatest variety.</span>
The correct answer is C.
Glad i could help:)
