What do yo think @Aureyliant
I'm not sure either.. sorry.
What do you think it should be @slade ?
A or D
can u explain to me what it is
A stimulus is any condition born as a result of environmental or other factors. Response is how our body tackles it.
For example, suppose you are running very fast, this results in heavy muscular activity and muscle cells start burning calories which in turn require increased amount of oxygen supply. This is a stimulus, body is now facing reduced supply of oxygen and now it has to do something in order to sustain. Correct?
yes i think
What does the body do?
So in response body increases the heart rate so that more and more oxygen is supplied to the muscle cells.
kinda i think
so its B
A. causes nerve cells to tell the hypothalmus to adjust the cells of the body, resulting in sweating
B. causes a similar response of hypothalmus, resulting in hormone (adrenalin relaease) to speed up heart to process more oxygen)
C is a stimulus(the allergen), which result in an inflammatory response from the body (a hypersensitivity reaction known as an allergy)
Eliminate D, cause fur doesnt grow as a result of winter.
