Answer:
A. Populations of native wetlands plants will recolonize the land.
Explanation:
From many years' wetlands are converted into farmlands as they provide retention of soil, proper food and clean water, and the cycling of nutrients. But wetlands should not be permanently converted<em> because it can increase the load on soil and add pollutants (pesticides or fertilizers) in the soil and groundwater.</em>
If the farming stops and water flows on the land again, the native plants present in wetlands will help to recolonize the land which is disrupted by farming activities.
Hence, the correct option is A.

Answer:
The fusion of two gametes to form a diploid zygote is called SYNGAMY.
Explanation:
During sexual reproduction process, exchange of DNA usually occur and this introduces diversity into the offspring that are produced. One of the ways by which exchange of DNA take place is called syngamy. Syngamy involves the bonding together of two sex cells leading to the formation of cell that has double amount of the chromosomes in the parent cells. The two cells that bond together are called gametes while the diploid cells formed is called zygote. The major function of syngamy is creation of variation; the genotypes in the formed zygote differ from those of the gametes.
