You are studying the stability of two double stranded nucleic acid samples. They contain double stranded polynucleotide of identical sequence and length and contain only G and C residues. The only difference is that one is RNA and one is DNA. You have forgotten to label your stock tubes and now you are unsure which tube contains the DNA sample and which the RNA sample. To distinguish, you perform a melting experiment and measure the amount of unfolded nucleic acid at different temperatures. You carry the experiment out at pH 10. Which tube likely contains DNA

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
