A-G-T-C-G-T

Explanation:

Nucleotide bases are the building blocks of nucleic acids, DNA and RNA. DNA is made up of four nucleotide bases, namely; Adenine, Cytosine, Guanine and Thymine. It is made up of two strands, where one strand is a complementary strand of the other.Complementary base pairing involves formation of hydrogen bonds between nucleotide bases with their partners. Cytosine forms three hydrogen bonds with guanine, and adenine forms two hydrogen bonds with thymine. In other words, during base pairing, Cytosine pairs with Guanine, while Adenine pairs with Thymine.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
