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.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
