The Ogallala Aquifer is the largest aquifer in the United States.
It occupies an area of 174,000 square miles, spreading across 8 Great Plains States.
Answer: <span>A) Slow to repopulate
------
Genetic variation is an advantage of sexual reproduction. It increases survival and the ability to adapt in a species. Species with genetic variation can respond better to environment changes, since the genetic variability allows some to be immune to disease or adapt better to a change, and live to reproduce.
Slow to repopulate is a disadvantage because the species cannot recover quickly after a large disaster. It also means they cannot adapt as quickly to an environmental change.</span>
Answer:
F: The oxygen atom has a greater attraction for the electrons in the surrounding covalent bonds than the
hydrogen atoms.
Explanation:
Between hydrogen and oxygen atoms exist a covalent bond. Oxygen is more electronegative than hydrogen atom hence its ability to get attracted to itself more electrons than hydrogen.
Answer:
B
Explanation:
Oxygen is the final acceptor of electrons in the process of oxidative phosphorylation. Without oxygen, the process becomes jammed with electrons.
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.
