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:
Zebroids are created by crossing zebra and any breed of equine. The main purpose of creating them is to develop a species that is resistant to diseases such as sleeping sickness and tztze, which are most common in both zebra and equines. Further, they carry genetic traits from both parents and are hostile in terms of benefits such as can run fast like horses and carry huge weight on their back easily. They have been extensively produced in African and Asian countries.
