Give two examples of organisms that differ greatly in their biotic potential

The two examples of organisms that differ greatly in their biotic potentials are -

1. Humans and orangutans - These have low biotic potential as they produce only one or two off springs at a time. They have long gestation periods and limited time span to produce offsprings.

2. Bacteria and Scorpio- These organisms have high biotic potential as they can produce thousands of offspring at a time. They also have a short gestation  time, so throughout their life, they produce more offsprings.

surface modification is a versatile tool and has been widely used in material science and engineering that has significantly facilitated the study and characterization of complex materials. at  matexcel, experienced experts in surface science can offer tailored efforts to meet the specific needs from our clients.

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.
