Answer:
Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:

A deoxyribose sugar.
A phosphate group.
A nitrogenous base.
DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.
The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.
Complementary Definition (Biology)
In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.
The likelihood of a cell firing is typically determined by adding both the excitatory and inhibitory synaptic input.
<h3>What is a cell?</h3>
A cell can be defined as the fundamental functional, structural and smallest unit of life, which is found within the body of an organism.
Generally, the likelihood of a cell firing is typically determined by adding both the excitatory and inhibitory synaptic input. Thus, the net sum of the excitatory and inhibitory synaptic input would determine whether or not a cell fires.

Answer:
D- NADH
Explanation:
Nicotinamide Adenine dinucleotide, is a co-enzyme which get reduced with hydrogen atoms from Kreb;s Cycle. Flavin Adenine dinucleotide is another co-enzymes(FADH2),
Generally, NADH2 transports hydrogen atoms into the matrix of mitochondria.
The hydrogen is spit to protons and electrons.
The protons are pumped by the proton motive force(PMF) from the matrix into the intramembrane spaces.
The high concentration of protons sets up electrochemical gradients, which supplies the energy needed for ATPs synthesis by ATPase enzyme, as the proton diffuses down the electrochemical gradient back into the matrix.
Therefore the energy from glucose is inform of NADH, and this has been harnessed , for ATPs synthesis.
Originally, there were only five bacterial cells. After one month, the amount of bacteria is doubled with ten bacteria. The growth is represented by the formula:
a42 = 5 x 2^1
After 42 months, the growth can be solved using this formula:
a42 = 5 x 2^42
