Equilibrium/ Equilibria proposes that once species appear in the fossil record,
the population will be in the state of
little or absent morphologic change. This is called a state of stasis. The
theory further proposes that the population is confined to infrequent and
geographical rapid events when significant evolutionary change happens. The parent species will the split into two
distinct species. This process if called cladogenesis.</span>
During telophase of Mitosis nuclear membranes of two separated nuclei are formed around each set of chromosomes.
<u>Explanation</u>:
Mitosis is the process of cell division part of the cell cycle. Mitosis is classified into four phases which are prophase, metaphase, anaphase and telophase. In prophase the nucleolus disappears, chromosomes start to contents and the mitotic spindle starts to appear and bind to the kinetochore of centromere of the chromosomes. In metaphase nuclear envelope breaks down and the chromosomes becomes fully condensed and organized on the metaphase plate in the middle of the nucleus, during anaphase chromosomes are pulled back to their centromeres with the help of spindle fibers and during telophase the chromosomes starts to decondense, the nucleous reappears and nuclear membrane reforms and spindle starts to disappear.

There are many environmental negative direct outcomes of unused excess nitrogen from nitrogenous fertilizers. One of these is eutrophication. Eutrophication is the excessive richness of nutrients in a water body as a result of fertilizer run offs from the land, which causes a dense growth of plants in the water. Other negative outcomes are: green house effects, acid rain and contamination of underground water which has negative effects on human health.
