Which of the following is not t true regarding the denaturation and reannealing of double stranded dna molecules?
-decreasing the salt concentration of the solution lowers dnas melting point
-increasing the gc content of dna raises its melting point
-single stranded dnas can only anneal to one another if they are 100% identical in nucleotide sequence
-dna is more likely to denature when exposed to a higher ph
-melting point is the temperature at which the dna is on half double stranded and one half single stranded.

Select all the correct answers. which statements fail to meet the requirements of a scientific claim? a) in the final 100 meters of a 10,000-meter race, an athlete's speed is more strongly related to anaerobic efficiency than to aerobic efficiency. b) flowers that reflect the most ultraviolet light are more likely to attract bees and other pollinators than flowers that reflect less ultraviolet light. c) even though evidence indicates that the solar system's planets follow elliptical paths, copernicus's model involving circular orbits is true. d) the evidence supporting newton's laws of motion was accurate in newton's time, but the universe operates differently today.
