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).
The urine osmolality is the measurement of urine absorption,
which substantial values indicate concerted urine and small values specify
weaken urine. Any foods that contained water also affects the osmolality of
urine. Some of the mammals are competent
of higher osmolality than healthy humans, most especially the rats, hamsters,
and mice if given no water.
