Answer:
The quadrant with more probabilities of overgrazing would be the one in which the drinkers and the rest zone is.
Explanation:
When a farmer has cattle for beef, most of them divide the land in quarters and limit each of them, this is to keep the cattle in only one quarter to make sure they eat all the forages in there and then they pass to the next quarter, this gives the other quarters (the forage) time to grow properly.
If the farmer uses all the four quarters, the natural behavior of the cattle would make the quarter that has the drinkers and the rest zone to be more likely to have an overgrazing.
This is because cows look for their aliments near them and near their comfort zone, they only move when the forage of that area is over.
Barbiturates are drugs that act as depressants on the central nervous system. They have a wide effect range, which means, the drugs can cause mild to total anesthesia effects. If the effectiveness of a barbiturate as a sedative depends on its ability to penetrate the non polar membrane of the cell, then based on this fact, hexethal will be more effective. This is because, it is more non polar than barbital; hexetal has a helxyl gruoup instead of the ethyl group present in the barbital.
I cannot found the images of the microscopy anywhere. But I can explain how you can differentiate a procaryote from a eucaryote under a microscope.
The first difference between them is the size of the cell. eucaryotes are generally much bigger than procaryotes. Procaryotes are visible only at x100 objective, but eucaryotes are visible starting from the x10 zoom.
The second difference is the presence of a nucleus in eukaryotes and the absence of it in procaryotes.
The third difference is the presence of organelles in eukaryotes and the presence of a cell wall in procaryotes (only visible at electronic microscopy).
