Answer:
I believe it is C
Explanation:
Scientists are still testing this theory so I believe it is a hypothesis.
Forgive me if I am incorrect.
Meiosis is important for organisms since it allows for genetic variation among organisms.
<h2>Further Explanation</h2><h3>Cell division</h3>
- Cell division is the process in which cells undergo division to form other new cells.
- There are two types of cell division;
<h3>Mitosis Division </h3>
- Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.
- The daughter cells have equal number of chromosomes as the parent and are identical to the parent.
- This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.
<h3>Meiosis division</h3>
- Meiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.
- In meiosis the daughter cells have half the number of chromosomes as the parent cells.
- Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.
- Meiosis occurs in two phases, that is, meiosis I and meiosis II
- During the process of meiosis several processes occurs that cause genetic variation among organisms.
- These processes include, crossing over, independent assortment of genes, among others.
<h3>Crossing over </h3>
- Cross over is the process that occurs during the prophase I phase of the first stage of meiosis known as meiosis I.
- During the process of crossing over, genetic material is exchanged between homologous chromosomes which enhances the genetic variation in organisms.

The correct answer is (c) They show which part of the brain are involved in specific activities.
The functional magnetic resonance imaging is used to measure the activity of brain by the detecting the change in the blood flow. This is done because the cerebral blood flow is associated with the neuronal activation. The functional area of brain has a higher blood flow that can be observed in functional MRI. The commercial application of functional magnetic resonance imaging is used in lie detectors. This technique is also used in research world and in some clinical trails. Physicians use this technique to see how risky a brain surgery can be. It is also used to learn how a normal, diseased, or injured brain functions.
