Answer:
The correct answer would be mitosis or M phase.
Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.
It is primarily divided into four stages:
- Prophase
- Metaphase
- Anaphase
- Telophase.
It results in the equal distribution of chromosomes into two daughter cells.
It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.
<u>Answer</u>: Natural selection.
<u>Explanation</u>:
- The concept of <em>natural selection</em> was given by <em>Charles Darwin.</em>
- According to this concept, in a given environment the organisms that possess <em>better adaptations</em> have<em> higher chances of survival</em> and, leave behind a <em>greater number of progenies</em>.
- When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to <em>survive</em> this outbreak due to resistance against malarial infection will be selected by nature and<em> hence, this is an example of natural selection.</em>
