The correct answer is A, the "promoter" site is the RNA polymerase binding site on a typical gene. This is how the process of gene expression begins. The RNA polymerase (a protein that builds RNA) binds to the promoter site of the DNA strand. It then begins the process of 'transcribing' the DNA code into an RNA strand, which can then be 'translated' into an amino acid chain to form a protein, which is the expression of the gene.

I hope my answer going to help you.
I believe the answer is Offspring that fail to develop. Post-fertilization barriers is where fertilization occurs but hybrid cannot reproduce. There two types of post fertilization barriers; Hybrid in-viability where the Zygote cannot complete development b/c genetic instructions are incomplete. The other one is Hybrid sterility where the hybrid organism cannot produce offspring b/c chromosome number is odd.
Answer: Ind. Variable: Band-Aids; Dep. Variable: Healing Time
Explanation:
An independent variable is a variable manipulated by the experimenter in order to cause an effect/outcome. The dependent variable is dependent upon the independent variable.
