Sarah and john are having a discussion on genetic diversity. sarah believes that it happen over a long period of time. john it happens immediately. who is correct? a. sarah is correct because genetic diversity occurs over a long period of time. b. john is correct because genetic diversity occurs immediately. c. both are correct because genetic variation can occur or long period of time. d. neither are correct because genetic diversity occurs over any period of time

Genetic diversity can be defined as the process of the variation in the genetic information of the organisms occurring naturally over time. This process of genetic variation leads to speciation, which results ti the evolution of the new species. Genetic variation can occur over a long period of time, or it can happen suddenly.

Over the time, by the process of natural selection, the strong genes get selected and passed on while the irrelevant one are eliminated. And over a long period of time, this continual process of natural selection leads to genetic diversity. Random mating, and fertilization also leads to the genetic diversity in a population.

On the other hand, the events, such as mutation, often leads to the sudden genetic diversity.

Hence, Sarah, and John both are correct. The correct answer is 'option C'.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
