tia_tia [17]

Answer:

C) decreased functional reserve

Explanation:

Ageing is a biological process which leads to the loss of function of the tissue and cells of the organism.

The biological ageing is determined genetically and can be correlated with the chronological ageing. The ageing is also influenced by the environmental factors which could interfere with the physiology, anatomy and morphology of the organisms.

The cell division cycle gets arrested to prevent the proliferation of these damaged cells and to remove the harmful factors from the body. This leads to the loss of function of the cells and tissues.

Thus, Option-C is the correct answer.

Delvig [45]

The question is incomplete as it does not have the options which are:

a) DNA

b) AGCT

c) PCR

d) SNP

Answer:

PCR (polymerase chain reaction)

Explanation:

The polymerase chain reaction is the technique which replicates and produces multiple copies of the DNA molecule artificially in a short period of time.

The PCR technique employs a variety of enzymes and all the prerequisites which are required in the DNA replication in vivo conditions.

In the given question, if the genome of the mummy has to sequence then after the collection of samples from the bones, the DNA has to replicate through the process of PCR. The samples from the different bone structures can be compared and analysed and a complete genome sequence can be analysed.

Thus, PCR is correct.
