The answer is meiosis. 

In meiosis, this process produces 4 daughter cells which are all genetically different to each other and their parent cell. They have only half of the chromosomes. This is because, at one point in the process before the cells divide, parent do not copy their genetic information, which ends up each daughter cells only receiving half of the chromosomes after division.

The daughter cells are also said to be haploid, and in human, these cells are usually gametes, which are for reproduction, so that after 2 of these haploid cells join together, the correct amount of chromosomes can be restored.

Vikki [24]

<u>Answer</u>: The answers are matched as follows:

African forests have been hunted to near extinction levels to obtain ivory-------------->human exploitation

The eruption of mount Saint Helens destroyed some populations of conifers------> natural disasters

An infection with a fungus reduced the population of North American Elm trees ----> disease

Increasing global temperatures have altered migration patterns of humpback whales ------>climate change

<u>Explanation</u>:

  • <em>Human</em> <em>exploitation</em> is the unethical or selfish use of resources to satisfy their own personal needs or for any profitable activity which harms the resources in such a way that they get limited. Humans have been hunting elephants to obtain ivory for many purposes such as making jewellery etc. and earning profits from it. Due to such extensive hunting they have driven the elephants to a level of extinction and thus, this is a form of human exploitation.
  • Mount Saint Helens is a volcano and its eruption which harms the population of the trees in the area is a form of natural disaster since volcanic eruption is a <em>natural</em> <em>phenomena</em>.
  • Fungal infection is a <em>disease</em> which is cause by the microorganisms which harms the population of the Elm trees.
  • Increase of global temperature is a type of climate <em>change</em> and thus, this effect of alteration of migration pattern is caused by climate change.
