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:
ionic bond: An attraction between two ions used to create an ionic compound. This attraction usually forms between a metal and a non-metal. covalent bond: An interaction between two atoms, which involves the sharing of one or more electrons to help each atom satisfy the octet rule.
Explanation:
By helping the ones who are already endangered and minimize habitat loss, global warming, etc.
The flexor digitorium profundus muscle inserts on the distal phalanges of digits II through V. The flexor carpi ulnaris muscle is one of the only anterior fore arm muscles innervated by the ulnar nerve, while the flexor pollicis longus muscle has its origin on the radius and the interosseous membrane and the flexor digitorium superficialis muscle inserts on the middle phalanges of the digits II through V.
