Answer:
<h3>Asexual reproduction results in variations in DNA.</h3>
Explanation:
This can happen because you have recessive and dominant characteristics passed down. So you can get a totally different chromosome that doesn't come from your parents because your grandparents may have had it or great grand parents, the line keeps going .
Food webs normally start at the bottom and work their way up. Like the plants will be at the bottom, and then each level shows the animals getting bigger while losing energy. You continually lose energy as you work your way up an ecosystem, so normally there are only three or four levels. I hope this helps!
Answer:
1. Leads to mixing of genetic materials hence variation within species
2. Leads to offspring with hybrid viguor that tend to show high and adaptability to environmental conditions.
3. Variations due to sexual reproduction leads to improvement of species hence evolutionary changes that may bring about specialisation
