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:
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.

Answer:
Hi, there the answer is
C.It is a frameshift mutation that changes many amino acids.
Explanation:
Due to the triplet nature of gene expression by codons, the insertion of the single Adenine nucleotide will disrupt the reading frame of the gene (frameshift mutation), such that it is no longer evenly divisible by three.
Thus, resulting in a completely different translated protein from the original.
Hope this helps :)
Answer:
Option A
Explanation:
Renewable resources of energy are clean source of energy. They are sustainable as they are readily available, can be used again and again and do not produce any pollution neither during production stage nor during usage stage by an individual.
There are very nations in the world which are oil rich and country itself has no oil reserve. In such scenarios, the dependency of nation on other countries increases. But in lieu to in-house renewable energy resources, country will not import oil from other nations
Hence, option A is correct.
You didn't put an image of the graph lol
