If purple is dominant, the genotype of the purple flower could be PP or Pp, as both would give a purple colour. However, if the crossed flower turned out to be white, we could say with certainty that the genotype of the purple flower is Pp as the genotype of the white crossed flower would be pp, which would not be possible if the purple flower's genotype was PP.
Answer:
Sodium chloride removes proteins from DNA and helps in DNA precipitation.
Explanation:
The Deoxyribonucleic acid (DNA) is negatively charged due to the highly polar phosphate groups that make up the phosphate backbone. The molecules of water are also highly polar and they have positive charge, thereby water molecules interact with the negative charges of the DNA. The sodium chloride generates temporary attraction forces between sodium (positive) ions and the DNA backbone (negative), thereby DNA can be disassociated from the aqueous layer. Moreover, sodium chloride helps to remove proteins (histones) that bound to DNA and also helps to maintain proteins in the aqueous layer.

Answer:
Pentanol, glucose and fatty acid.
Explanation:
Pentanol, glucose and fatty acid are the three molecules which are present in the given model number 1. In the model, there are three different molecular diagrams for each molecule. The first one is ball and stick model, the second one is Lewis structure and the third one is line drawing method. All diagrams for a same molecule is totally different from another.
