How can RNA be distinguished from DNA?

Are structures are found in prokaryotic cells except:

In tomato plants, purple stems (P) are dominant to green (p), and red fruit (R)  is dominant to yellow fruit (r). If a heterozygous purple-stemmed, red-fruited plant were self-fertilized, what proportion of the offspring would have purple stems and yellow fruit?  

The sequence of nitrogen-containing bases on the template strand of DNA of a gene determines the sequence of:

 Assume that an incompletely dominant gene controls the feather color in chickens so that BB produces black, BW produces a slate-gray color called blue, and WW produces asplashed-white.  A second gene on a separate chromosome controls comb shape, with the dominant gene R producing a rose comb and the recessive genes rr producing a single comb. If a pure breeding black, rose-comb chicken is mated with a white, single-comb chicken, what proportion of the offspring will be white, single-comb chickens?

Identify structure 3 (the dark structure inside structure 8).

_________ contain(s) hydrolytic enzymes to digest biological macromolecules, worn out organelles, and material from endocytosis.

An organisms’s physical or observable traits due to the genes it possesses is known as the:

Sled dogs can require 10,000 calories a day while running. This is an example of which characteristic of living organisms:
