Earth's orbit affects weather and climate why summers are hottest in the Southern Hemisphere when Earth is closer to the Sun. We need to know that .......
<h3>Weather and climate</h3>
When in the Northern Hemisphere it is winter, in the Southern Hemisphere it is summer. Likewise, when it is spring in one hemisphere, it will be autumn in the other. This is precisely because of the position that each hemisphere occupies in relation to the Sun in that period, which determines the amount of solar irradiation it is receiving.
With this information, we can say that the tilt of the earth is very important for the climate and weather of the planet, because when the Northern Hemisphere is closer to the sun, the summer will be hotter, and consequently in the Southern Hemisphere, it will be winter.

Answer:
Below is a definition of the distinction between mitosis as well as meiosis.
Explanation:
<u>Mitosis:</u>
- The genetic information (DNA) in something like a cell throughout mitosis has been duplicated as well as split evenly into two cells.
- An orderly sequence of circumstances known as the cell cycle moves through it's dividing cell.
<u>Meiosis:</u>
- Meiosis seems to be the mechanism whereby the gametes throughout sexually reproducing individuals are produced.
- Gametes have been formed in gender gonads and just like the new cells, constitute two complete sets of chromosomes.
In animal and plant cells genetic information if contained within a nucleus, in bacterial cells there is no nucleus and so the genetic information is found within the cytoplasm of the cell but is not 'contained' in a more specific area. A small amount of DNA in the bacterial cell may be contained in an area of the bacteria called a plasmid, however not all bacterial cells have a plasmid.
Prevent loss of Genetic Diversity and Inbreeding
The knowledge of parentage provides one with information about the origin and identity of the parents.
The variations and changes in the genes of the progeny of the parents can also be understood by the knowledge of the parentage.
Population of wild endangered species can benefit from the knowledge of parentage as this can help in prioritizing original gene material, avoid inbreeding incidents , important tool to manage cross between species hence aiding in the prevention of genetic diversity and loss of population.
In zoos, inbreeding is very common due to small populations which can lead to an increase in homozygous populations instead of heterozygous ones. Decrease in heterozygous populations implies decrease in genetic variability.
∴ Knowledge of parentage in zoos can help with that.
