<span>This is because, people, generally,
have two kidneys and are also able to function properly with one functional

not doing the surgery outweighs that of doing the surgery. </span>
Answer:
Cindy is the one who is contributing most to the destruction of the ozone layer.
Explanation:
The deforestation caused by Cindy's father and the release of gases that her boyfriend's car contributes a lot to the destruction of the ozone layer. However, cindy is the one who is contributing the most aggressively.
This is because, scientists, after much research and studies, were able to prove that the Fréons gases are the ones that contribute more efficiently to the destruction of the ozone layer. These cases are formed by carbon, fluorine and chlorine atoms that have great destructive power when emitted into the atmosphere.
The correct answer is R-r.
Heterozygous is where the alleles of diploid organisms are different.
Alleles are variations where DNA sequence of gene varies from one individual to another. Other genes may have one allele because if there is low variation. There are genes where by one alleles may be common and others are rare.
Sometimes it can be a disease which causes variation and others may be a healthy. One allele is being inherited from male parent in diploid organisms and others from female parent.
Answer:
