Answer:

All of the above.

Explanation:

Reflex arc may be defined as the neural pathway that control the function of the reflex system of the body. Two main types of reflex arc are somatic reflex arc and autonomic reflex arc.

The afferent neuron carries signal from the receptors to the integrating center via the interneuron. The efferent neuron carries signal from the integrating center to the effector organ via the inter neuron.

Thus, the correct answer is option (e).

4vir4ik [10]

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).

What happens to the motion of an object when the forces acting on it are balanced
Ira Lisetskai [31]

When the entire group of forces acting on an object is balanced, the vector sum  

of the forces is zero, and the effect of the group of forces on the object's motion  

is identical to the effect of no force at all. The object continues in constant uniform  

motion.  

To state the outcome of the situation in three different ways:  

-- The object's acceleration is zero.  

-- The object's velocity is constant.  

-- The object's speed and direction of motion don't change.  

The direct answer to the question is: Nothing happens to its motion.
