<span>D. can incorporate new scientific discoveries. should be the answer. Hope I helped!</span>
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.
The three major clades of bilaterian animals are the <span>ecdysozoa, lophotrochozoa, and deiterstomia.
Ecdysozoa are organisms that include insects, crustaceans, chelicerata, and myriapods. Lophoytochozoa include fossil organisms. Deiterstomia include chordata, echinodermata, and hemichordata.
Bilaterian animals have bilateral symmetry, meaning that they have a head, and a tail, as well as back and belly.

Answer:
e. None of the above
Explanation:
For me as a Researcher, the reason could be increased Concentration of your DNA sample which you are using as your template. Try to decrease the concentration of DNA (up to 100 ng per reaction is enough and can increase up to 200 ng). so the reason for getting non specific bands is increase concentration of DNA which results in non specific amplification and also degradation of DNA in the reaction which you can see in your gel electrophoresis results.
i always corrected my results using the same technique that is lowering the concentration of DNA between 100 and 200 ng per single reaction of PCR.
For the first question, i think the correct answer is A. Normal cells undergo apoptosis while cancer cells don't. For the second question, The answer is option B.<span> </span><span>Cell division has two checkpoints namely, G1
checkpoint and spindle assembly checkpoint. The checkpoint which determines if
division has properly occurred is the G1 checkpoint. At this point, is a damage
in the DNA is detected or the has not reach the optimum size, the cell is
stopped in G1 and is not allowed to proceed to further process.</span>
