Meiosis serves two purposes in life, one is to reduce the number chromosomes by half. the other is to create genetic diversity. Two events happen during Meiosis which help to create genetic diversity. The first happens in Prophase I and is called Crossing over.
<u>Explanation:</u>
A cell division type that helps in the chromosome reduction in the parent cell into 4 gamete cells is known as Meiosis. For sexual reproduction to take place this process is very essential for the production of sperm and egg cells. This process is required to produce egg and sperm cells for sexual reproduction.
These cells unite to form a single cell in which the chromosomes are restored. Crossing over is done to generate genetic diversity and the homologous chromosomes are positioned in a random manner. In this stage the number of chromosome is reduced from 2n to n.
Answer:
The experimenter hypothesized that fertilizer would make the plants grow taller. The results show that, on average, plants with fertilizer grew 0.7 cm taller over the course of 12 days. This small amount of height increase could be attributed to the fertilizer or may be caused by natural differences in the plants.

Explanation:
The quantity of energy decreases down each trophic level as only 10% of the energy at the upper level is transferred to the next level, the remaining 90% is lost as heat during metabolic process. Through the energy pyramid we can explain how energy is lost at each trophic level, the number of consumer at each trophic level that will benefit from the transfer of energy depends on the size and quality of the energy from the autotrophs
Your answer would be:
Temperature and amount of available water.
Abiotic: a non-living factors that affect organisms and their ecosystem. Can be a physical or chemical part.
Temperature and water as we know, are not living (biotic) components.
