If 28% of the nucleotides in a DNA molecule contain the base T, what percent will contain the base G

22% base G

Explanation:

background info

nucleotides pairs:

T-A (thymine- adenine)

C-G (cytosine- guanine)

because they are pairs, there is an equal amount of T and A. and an equal amount of C and G

# of T= # of A

# of C= # of G

solve

28% is T, then 28% is A

28*2=56%

100-56= 44%

44% left for C and G

44/2=22 (because C and G amounts are equal)

22% C and 22% G

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
