Because gametes (sex cells) are the only cells that pass along genetic information. Somatic cells are the cells that have already differentiated into various organs or tissues. They can't pass on a mutation to offspring because they're not involved in creating it.
The answer is D. They fuse during sexual reproduction
The right answer is B and C.
For proposal C, I will give you an example, that of an autosomal recessive disease. If a parent is heterozygous for an allele causing an autosomal recessive disease (due to a mutation), it may be that it transmits the allele to its descendence, as it may not be able to transmit it (since in one heterozygous subject, not all of its gametes carry the mutated allele) and thus the mutation will no longer be copied through the generaitons.
Each individual is genetically unique. Its genes are distributed along chromosomes contained in the nucleus. Mutations can lead to the appearance of different versions of genes: alleles. A diploid individual has two copies of each gene, which may be identical or different alleles. Mixing during sexual reproduction partly explains the genetic diversity of individuals.
Answer:
Litmus milk is an undefined medium consisting of skim milk and the pH indicator azolitmin.
Azolitmin is purple between pH of 4.6 and 8.2. It turns pink when pH reaches 4.5 and blue at a pH of 8.3.
Lactose ferminatation turns the litmus pink due to acidity. If litmus is reduced during lactose fermentation it will turn the medium white. Acid may cause an acid clot this is due to the casein precipitating. Heavy gas production can cause stormy fermentation, this is due to the breaking up of the clot.

It is necessary to classify organisms because: ... It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences.
