D. Number of protons in an atom's nucleus
No!!
Size of a cell doesn't depend on size of an
organisms, Their number maybe different 'cause of size but their cell
would remain same.
Hope this helps!
I honestly think it’s the second one
Sorry if I’m wrong
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.
