According to the mutation accumulation theory, ageing organisms experience an increase in frailty and mortality due to the haphazard accumulation of mutations that harm them.
The traditional evolutionary explanation of ageing explains why mortality increases with age: as people age, their lifetime fertility declines, therefore their ability to continue to survive has a smaller impact on their ability to reproduce. But in addition to fertility, successful reproduction frequently entails intergenerational transfers.

There are two types of nucleic bases . Purine and pyramidine . Hence purine comes under pyramidine. Thymine is represnted by T symbole.
The answer is C. They move into an ecosystem :)
Answer: Water has unique properties that makes it an amazing substance. The cohesive forces are the intermolecular forces (hygrogen bonding and Van der Waals forces) which develops the tendency of that resists the liquids to separate.
As a result of this the water molecules forms droplets. These bonds lies in the molecules of the same substances.
Example rain droplets rather than a fine mist, water forms droplets.
