hope this helps
have a good day :)
Explanation:
Answer:
Because no herbivores would want to eat it, and it could ward most predators away easier.
Answer:
Epigenetic effects can be caused by DNA heterochromatin and/or histone silence or activate.
As such, they can different chromosomes or certain chromosomal regions and be responsible for parental imprinting or influencing gene activity in oxidation and reduction.
Patterns of nucleotide demethylation and hypermethylation are often activate when cancer cells are compared to normal cells.
Explanation:
Cells acquire various patterns of gene expression during differentiation to adapt to a changing environment. Epigenetic and genetic alterations are considered as two independent mechanisms that participate in the onset and progression of cancer. Epigenetic mechanisms can be as important for biological events as genetic mechanisms, which do not imply a change in the DNA sequence, but do have an important role in the modification of gene expression.
Greater than 7 because I have on my test not worry
Answer:a. The normal gene function is required for the viability of the zebrafish.
Explanation:
It is mentioned that if the gene responsible for forming stripes on its body is inactivated by mutation then fish without stripes will produced.
This will lead to the absence of phenotypic character that is strips on the fish. The other genes which are responsible for the survival of the fish will function normally thus this will be untrue that normal functioning of the gene required for expressing horizontal strips is also necessary for the survival and viability of the zebrafish.
