Based on the graph, at which point is the death rate most likely greater than
the birthrate?
Answers
Answer:
100
Explanation:
there is a certain amount of food and resources to sustain a certain amount of individuals in a population. Since the individuals exceeds the amount of resources at 100,000 individuals you would usually see the death rate higher than birth rates to balance out the number of individuals to the number of resources so there is enough for all the individuals there.

Answers
The permeability of the neuron membrane to Na and K differs with the stages of action potential as follows:
A is greater than BA is greater than BB is greater than AWhat is an action potential?An action potential is a sudden change in the voltage across the membrane of a resting neuron resulting in transmission of impulse.
An action potential results in variation of neuronal membrane to sodium and potassium ions.
A. Resting neuron's permeability to K >>> B. Resting neuron's permeability to Na
Thus, A is greater than B.A. Neuron's permeability to Na during the rising phase of an action potential >>> B. Neuron's permeability to K during the rising phase of an action potential.
Thus, A is greater than B.A. Neuron's permeability to Na during the falling phase of an action potential <<< B. Neuron's permeability to K during the falling phase of an action potential.
B is greater than A.Therefore, the permeability of the neuron membrane to Na and K differs with the stages of action potential.
