Answer:

E. glucagon

Explanation:

Bone remodeling is a natural process that takes place in the human body continuously. The process destructs the old and mature portion of the bones and replaces it with the formation of new bones.

The process of bone remodeling is controlled by the hormones and the mechanical stress the bone faces.  The hormone which controls the process is the parathyroid hormone and the calcium which is required during the process of synthesis of bones. The factor which is not involved in the process is glucagon.

Thus, glucagon concentration does not affect bone remodeling.

Which best exemplifies the concept of neuroplasticity?
KonstantinChe [14]
The correct answer is "the formation of new brain cell connections as the result of reading a book".

Usually, neuroplasticity is apparent in young children when the central nervous system has an abundance of neurons. This is always in the context of forming new brain cell connections or synapses that will lead the person to access the information quicker. This also exemplifies the principle of use and disuse when it comes to knowledge. 

The other choices concerns the skeletal system, cardiovascular system, and the endocrine/reproductive system; all of which do not have a relation with neuroplasticity.
