Answer:

b. Engineers should consider how much pollution their devices create because of how human health is affected.

Anthropocentrism, is a worldview that argues that humans are more important and significant that any other entities or species in the world. This view point argues that humans possess greater intrinsic values compared to other species; this viewpoint sees humans as superiors while other entities are inferior to them and hence can be used by humans for their own benefit.

Therefore the anthropocentric viewpoint as it relates to environmental ethics implies that engineers should consider how much pollution their devices create because of how human health is affected.

Click and drag each label to the accurately identify the components of the visceral baroreflex
QveST [7]

The right answers are on the attached image.


Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.

As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.
