Thirty-five percent of the trees cut down are used to make paper. That means sixty-five percent of the trees cut down are used for something other than paper. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
Eukaryotic cells are cells with a nucleus while prokaryotic cells do not have a nucleus.
The answer is <span>Without genetic diversity, natural selection cannot occur.
</span>In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. In order for natural selection to occur, the genetic diversity must be present within the population. That way, natural selection will have more "choices" so it can favor those variations t<span>hat will increase the chance of survival and reproduction.</span>
<span>Any of the above is possible because anything can happen to a gene when it is transcripted. Mutation happens when there is a defect of coding the right genes resulting to a change of DNA sequence. DNA may be reduced or unchangeable by a transcription factor because of mutation in a gene.</span>
