Answer:
<em>The correct option is B) regulation of mitosis</em>
Explanation:
Cancer can be described as a group of diseases which result from uncontrolled, abnormal cell division. The cell division by which the cells divide (except sex cells) is termed as mitosis. Hence, scientists will be studying the regulation of mitosis if they are to find a cure for cancer.
Other options like option A are not correct because only sex cells divide by meiosis. Hence, regulation of meiosis will not cure cancer.
Maybe biosphere and geosphere?
Answer:
The phenotype of the rabbit is the absence of fur colour and the genotype is the alleles rr.
Explanation:
The genotype can be described as the genes which are present in an organism. Genes are made up of alleles. As the rabbit in the question carries the alleles, rr, hence it is the genotype of the white albino rabbit.
The phenotype can be described as the physical appearance that results from the particular genes present in an organism. As the white albino rabbit carries the alleles,rr, due to which it doesn't have fur, hence no fur is the phenotype of it.
Answer:
D. Type in human immune system + HIV effects.
