I found the exercise on the internet and attached is the image of the DNA strand mentioned in the question.
Between each Thymine - Adenine bond there are two hydrogen bonds, while in each Guanine - Cytosine bond there are three hydrogen bonds. This is important because allows each base to connect only with that that is the correspondent.
So, the number <span>hydrogen bonds that exist between DNAs dna strand and its complementary strand is 19.
2bonds</span>×2 (1 Adenine + 1 Thymine) + 3bonds×5 (2 guanines + 3 cytosines) = 19 bonds

Answer:

Greater than zero, and equal to the rate of the reverse reaction

Explanation:

this is an incomplete question in the first place, i saw the complete format online hence the answer am giving here.

Before any C2H5CO2CH3 is or was removed, the system is said to be in equilibrium.

This means that the rate of consumption of reactants and rate of generation of products are greater than zero and are equal, that means that both the forward and backward reactions are occurs at these rate.

Julli [10]

The effect nervous system has on the heart rate is

Stimulation by parasympathetic nerves causes the heart rate to slow down.

The two branches of the autonomic (involuntary) nervous system regulate heart rate. The parasympathetic nervous system and the sympathetic nervous system (SNS and PNS) (PNS). To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The hormone acetylcholine is released by the parasympathetic nervous system (PNS) to reduce the heart rate. Your heart rate may briefly increase due to stress, coffee, and excitement, whereas it may temporarily decrease due to meditation or deep, steady breathing. Any amount of exercise will raise your heart rate, which will stay up as long as you keep exercising.
