If the ventral respiratory group (VRG) of neurons was destroyed: If the ventral respiratory group (VRG) of neurons was destroyed: breathing would stop. tidal volumes would increase. alveolar ventilation would increase. pulmonary ventilation would increase rapidly.

Breathing would stop.

Explanation:

Respiratory centre is the group of neuron located in the brain mainly in the pons and medulla. In the medulla, there is two types of neuron group: the dorsal and the ventral group of neurons.

The ventral group of neuron in medulla controls the muscles involved in the inspiration and expiration of the lungs.

Since the inspiration and expiration are associated with the breathing mechanism therefore if the ventral neurons will be destroyed then the breathing would stop.

Thus, the selected option is correct.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
