Answer:
The answer is that NE injection has inhibitory effects on the paraventricular nucleus VPN.
Explanation:
It can be said that the destruction of the paraventricular nucleus (PVN) would produce a hyperphagia, on the other hand, the injection of norepinephrine (NE) would increase the feeding in the rats. This is because NE injection has inhibitory effects on the paraventricular nucleus. If neuronal activation in the paraventricular nucleus is increased, food intake by rats would be decreased.

The carbon 14 left from this animal is 3 grams of 24 grams which is: 3g/24g= 1/8 times of its original mass. Then, the age of the animal fossil would be:
final weight= initial weight * (1/2) ^ time/half-live
1/8 initial weight = initial weight * (1/2) ^ time/half-live
log2 1/8= log2 (1/2) ^ time/half-live
-3= -time/half-live
time= -3 * -(half-live)
time= 3 half-live
If the half-live is 5730 years, the age would be: 3* 5730= 17.190 years.
