Eukaryotic cells have a nucleus and prokaryotic cells do not.
Answer:
a. At the cytosol surface
Explanation:
- The G protein coupled receptors have seven transmembrane alpha helices and because of this they are able to pass through the cell membrane seven times.
- Like every protein, this receptor also has to terminals - one is the N-terminus and the other is the C-terminus.
- The N-terminus is the amino end of the receptor whereas the C-terminus is the carboxyl end of the receptor.
- The N-terminus lies on the extracellular side and then it crosses the membrane 7 times such that the C-terminus faces the inside that is towards the cytosol.
- The fact that the loop on the cytosol side between helices 5 and 6 helps us to know that the 7th loop must go outside and by coming back in the C-terminus would eventually face the cytosol.

Poverty is believed to be the leading cause of overpopulation. A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population.
