When studying motivated behavior, including eating, rats can be used to predict human behavior because the in a rat's brain is similar to that of a human.

Lateral hypothalamus and ventromedial hypothalamus

Explanation:

The studies on human behaviour can be associated with the studies on the rats as they both belong to the same family that is mammals.

The studies on the human eating behaviour like the part of the brain involved in the stimulation of hunger when studied in the rats were found that the same art of the brain that is the hypothalamus, both the ventromedial and the lateral hypothalamus is involved in the production of the hunger in the rats.  

Thus, Lateral hypothalamus and ventromedial hypothalamus is correct.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
