Which phase of meiosis occurs right after crossing over takes place

The correct answer is metaphase I.

Explanation:

A kind of cell division, which leads to the formation of four daughter cells each comprising half of the number of the chromosome of the parent cell, as in the generation of plant spores and gametes is known as meiosis.  

In meiosis, when cross over takes place between the chromatids, the homologous chromosomes trade the segments of genetic substance, leading to the formation of a new combination of alleles. The phenomenon of crossing over takes place at the time of prophase I of meiosis prior to the alignment of the tetrads along the equator in the metaphase I stage.  

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
