The three major types of pollution are air pollution, water pollution, and land pollution. Sometimes, air pollution is visible. A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible.
A mutation can allow a organism to adapt to the environment and example can be the case of the peppered moth which has two variations a white colored one and a black colored one. The white colored ones were able to survive better that the darker ones because of how they were able to camouflage with the lichen located in the trees. However, after a while smoke particles that were released by industries darkened the trunk of the trees making the white moths visible and allowing the darker colored ones to survive. Another example can be on how organism can be resistant to bacteria this allows the animal to survive and reproduce offspring with the same mutation. I hope this helps...
The Telophase 2 is the fourth step or process during Meiosis (cell
division). During Telophase 2, a nuclear envelope forms around each set of new
chromosomes. In this stage, cytokinesis occurs, which is responsible for
producing four daughter cells each with a haploid set of chromosomes. During
the crossing-over phase some chromosomes are observed to have segments that
have recombined with the original parent chromosomes.

When the phase is over, the two
cells are now finally separated and their nuclear membranes are fully formed
causing the meiosis cell division to be completed.</span>
