Answer:
Neurons have stable, relatively unchanging internal environments.
Explanation:
Neurons or nerve cells is the structural and functional unit of the nervous system. Neurons consists of the dendrites, axon, cell body and different cell organelles.
The neurons have mitochondria that meets the high ATP requirement and and consume more oxygen. The network of rough endoplasmic reticulum and ribosomes produce large number of proteins in neuron. The internal environment is never stable and gets changed as the nerve impulse transmission occur through the neuron. The membrane potential of the neuron gets changed and changes its internal environment.
Thus, the correct answer is option (B).
Answer:
a reflex
Explanation:
an example of this world be how fast you react to something such a doctor hitting your knee to test your reflex and your leg moving up
Answer:
7683.2 Joules
Explanation:
We can calculate potential energy using the equation that is used to calculate the work done by a conservative force, in this case, gravity.
U(x)<em>gravity = </em>mgy
U represents potential energy, m is mass, g is gravity, and y is the height.
U(x) = (80 kg)(9.8 m/s^2)(9.8m)
Potential Energy = 7683.2 Joules
I believe the answer is:
The "spontaneous firing rate" of a neuron refers to <span>its rate of producing action potentials even when it is not stimulated.</span>
