An Asexual reproduction means that the parent organism will simply split into two child organisms, and that there will be no mixing of the DNA, as it is the case in case of the sexual reproduction which mixes up the DNA. Therefore the child and the parent organism will contain exactly the same genetic material

It is very dark down there, it is so deep that it makes it hard for scientists to be able to survive down there, & there is not really any ready to use equipment since we don't know how it is down there.
The population of pepper moths that were adapted to the pollution would be spotted by birds and die but the population that did not adapt would survive because they are a lighter color and can blend in with the trees.
Answer:
a regulatory protein binds to DNA which blocks transcription
Explanation:
Negative control of gene expression includes the binding of certain regulatory proteins to the regulatory sequences. This binding prevents the expression of certain sets of the gene. For instance, binding of repressor protein to the operator sequence of lac operon prevents the expression of structural genes of the operon. This pattern of gene regulation is called negative regulation. The binding of the repressor to the operator sequence does not allow the RNA polymerase to transcribe genes since the operator and promoter (binding site for RNA polymerase) sequences are present in close vicinity.
