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.
Your best bet is most likely going to be B
A Chromosome holds part or all of the genetic material of an organism. It also includes packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.
So yes your best bet is B.
During the lifecycle of the plant we can encounter both haploid and diploid forms.
Out of the macromolecules present and required for the survival of an organism, the type of macromolecules that are categorized as enzymes would be proteins. Certain proteins can act as biological catalysts that aid in chemical reactions by helping speed up the rate of change of a reaction from reactants to products.
