Starch and Cellulose is formed when many disaccharide molecules are combined
I am pretty sure it's D) use of electrons focused by magnetic fields.
Hydrogen bonds exists between the DNA strand and its complementary strand such that; there are two hydrogen bonds between every A and T, and three between every C and G.
Therefore; in this case there will be (2 ×3 ) +(3×3) = 15 hydrogen bonds for the above strand. this is because Adenine binds to Thyamine with two bonds (3 pairs) and Guanine binds to Cytosine with three bonds (3 pairs).
To create enviromental laws to protect natural resourcesfor human consumption.....i think
