Explanation:
The plant may not be present in 25-50 years due to ecological succession. in ecological succession, the vegetation such as small plants that is present replaces by the more suitable vegetation such as trees because the vegetation (small plants) did not receive nutrients and sunlight so they are unable to grow and finally dies due to lack of basic needs. So that's why plant may not be present 25-50 years.
The Avery–MacLeod–McCarty experiment was an experimental demonstration, reported in 1944 by Oswald Avery, Colin MacLeod, and Maclyn McCarty, that DNA is the substance that causes bacterial transformation, in an era when it had been widely believed that it was proteins that served the function of carrying genetic.
The answer to this question would be: <span>Extra chromosomal material</span>

The disease will cause the child to have an intellectual disability. The primary risk factor for this disease would be old mother.
The correct answer that would best describe the given description above is the word SUPERCOILING. SUPERCOILING permits DNA <span>to maintain a relatively stable conformation when the helix is slightly underwound or overwound. It</span><span> </span><span>is</span><span /><span> an expression of the strain on that strand. Hope this answer helps. </span>
