Answer:
Many amino acids in an enzyme molecule carry a charge . Within the enzyme molecule, positively and negatively charged amino acids will attract. This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules
Answer:
The formula for exponential population growth is dN/ dt = rN.
Explanation:
In this equation d is the rate of change, N is the number of existing individuals, r is the intrinsic growth rate, t is time, and dN/dt is the rate of change in population size.
Answer:
Nitrogen fixation is a process whereby bacteria in the soil convert atmospheric nitrogen ( N2 gas) into a form that plants can use. ... Animals get their nitrogen by eating plants or other animals.

Hope this helps! :)
ANSWER: A. Exercise is important for the body to function properly.
Exercise deliver adequate amounts of oxygen and remove waste from body tissues by regulating nervous, respiratory, circulatory and hormonal systems in the body. During exercise, body tissues and other metabolic processes in the body requires oxygen.Low levels of oxygen and higher levels of carbon dioxides are mainly detected by sympathetic division of the autonomic nervous system which control the physical activity of the body by increasing heart rate, blood pressure and respiration as a result of this there is an increase in the amount of blood pumped per minute by the heart and oxygenated body gets distributed to the tissues. This also involves release of glucose by the liver as an energy reservoir to control the level of blood glucose pancreas secrete insulin hormone , thyroid gland is also stimulated in response to increase heart rate.
