Answer:
The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation.
Explanation:
The frontal lobe takes about 1/3 of the cerebral cortex.
Incomplete question. Here are the missing parts.
What will happen to the substances in this diagram to bring the concentrations closer to equilibrium?
A. The solute will flow into the cell from the surrounding environment.
B. Nothing will change--it is already in equilibrium.
C. Water will flow into the cell from the surrounding environment.
D. Water will flow out of the cell and into the surrounding environment.
My answer:
D. Water will flow out of the cell and into the surrounding environment.
The solute cannot pass through and go inside the cell, water has to flow from the cell to the surrounding environment to bring the concentration closer to equilibrium.
Answer:
The correct answer is E. none of the above. The population will drops below 100 when t ≥ 38.
Explanation:
Given A= A0 e^kt. The population 10 years ago is A0, the population today is A(10), and we have to find the value of "k" and then the time when population drops below 100.
So, A(t) = 1700 e^kt ⇒ A(10) = 1700 e^k(10) ⇒ 800 = 1700 e^k(10) ⇒
800/1700 = e^k(10) ⇒ln (800/1700) = k(10) ln e ⇒ -0.754/10 = k ⇒
k = -0.0754.
Now you have all the parameters, so you can find the time at which the population drops below 100.
A(t) = 1700 e^kt ⇒ 100 = 1700 e^(-0.0754)t ⇒100/1700 = e^(-0.0754)t ⇒
ln(100/1700) = (-0.0754)t ln e ⇒ [ln(100/1700)]/(-0.0754) = t ⇒
t = 38.
So, the population will drops below 100 when t ≥ 38.
