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.

Answer: <u><em>All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species.</em></u>
Explanation:
Answer:
The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era.
Explanation:
It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
