The radical in this question is OH.
The reason this will be a radical, is that the definition of a radical is the presence of an unpaired electron. This causes the radical to be unstable, desperately wanting to do something with the free electron that it has.
Oxygen has a charge of 2-, and Hydrogen has a charge of +1. When you pair them, you end up with a net charge of 1-, which is the presence of that unpaired electron. It will usually be written as: 
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.

Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
