The answer is D. Schist because it is an igneous rock, it could be found in a volcano.
Answer:
TRUE
Explanation:
If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.
The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.
The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.
When t < 3, P'' > 0.
When t = 3, P'' = 0.
When t > 3, P'' < 0, because the rate of population growth is slowing down.
Thus, if the population is in the final phase of logistic growth, the population is increasing at a decreasing rate (TRUE)..
Climate changes thats what im guessing .. not too sure though ... sorry
Answer:
If Clark had no ions in his nervous system, he would not be able to generate an action potentials.
Explanation:
An action potential occurs when a stimulus causes sodium channels to open in a neuron. Sodium floods in, making the inside of the cell more negative and the outside more positive. This is known as depolarization. Then, the Potassium channels open to allow Potassium out (Repolarization). A few too many K+ ions will leave the cell (Hyperpolarization), and finally, the Sodium-Potassium pump will bring the cell back to resting potential.
As you can see, the Sodium and Potassium ions are <em>essential</em> to action potentials in the nervous system. If Clark had no ions in his system, he would not be able to send any action potentials at all.
