Oxygen, carbohydrate glucose
Answer:
The correct answer is 20 years.
Explanation:
It is given that the growing rate is 2% or 2/100 = 0.02
This rate got increased to 150%
The formula for exponential growth is:
A = Pe^rt
Let the initial population be 100%
150 = 100.e^0.02*t
3/2 = e^0.02t
1.5 = e^0.02t
After taking log from both the sides:
ln(1.5) = 0.02t * ln(e) [ln(e) = 1]
ln(1.5) = 0.02t
t = ln(1.5)/0.02
t = 20.27
Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.
Answer: These contractions need energy from respiration , and some of this is released as heat. Blood vessels, which lead to the skin capillaries, become narrower - they constrict – which allows less blood to flow through the skin and conserve the core body temperature. This is called vasoconstriction.

1 billion, please correct me if I’m wrong!
you increase the chances of the existing bacteria mutating and becoming resistant, therefore making it harder to treat the next time around.
