The nitrogenous bases found in the DNA are classified into two groups. Identify each of the following examples and/or characteristics as true of Purines or Pyrimidines.

___ 6-membered ring of carbon and nitrogen atoms

___ 5 membered ring fused with a 6 membered ring

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

i think its both a and b
