Apopulation with a geometric growth rate of 1.6 has an initial population of 10 individuals. after 10 years the size of the population is expected to be
a. 1100
b. 1300
c. 16
d. 550
e. 900

A. 1100

Explanation:

∵ The population which is increasing with the geometric rate of b is,

Where,

a = initial population,

Here, a = 10,

If the population is growing by the growth factor of 1.6,

i.e. b = 1.6,

Then the population after x years,

If x = 10,

Hence, the population after 10 years would be,

Option 'A' is correct

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
