El Nino is a climate cycle where the temperature of the Pacific Ocean changes because of movements of air and ocean currents. During this period, the trade winds in the south weaken, causing the warm water to move from the Western region to the Eastern region.
El Nino climate cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America.
Opposite of El Nino is La Niña when the waters of the tropical eastern Pacific are colder than normal and trade winds blow strongly than usual.
The result of meiosis is that the offspring will have no genetic variation, which means that it has less of chance for surviving changes to the environment. What happens to the chromosomes is that they duplicate and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.

Explanation:
In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.
<em>For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.</em>
