In another experiment, Alex put similar pieces of waterweed into two more beakers of pond water. She added fertiliser to beaker E. She kept them both by a window. Suggest the results of this experiment.

The growth of waterweed plant is higher in beaker E.

Explanation:

The growth of waterweed plant is higher in beaker E because the waterweed absorb nutrients that is provided in the form of fertilizers. Fertilizers are the nutrients that is essential for the growth of plants. Those plants that has more nutrients available can grow faster than those plants which have no nutrients or less nutrients because these nutrients provides raw material for the formation of amino acids and enzymes that contributes in the growth and development of the body.

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.
