Researchers have found that wolves try lots of different trial and error tactics to solve the problem— they get at it physically. But at the first sign of trouble, dogs do something different. They look back to their human companion for help. This work hints that dogs may have lost some of their physical problem-solving abilities in favor of more social strategies, ones that rely on the unique sort of cooperation domesticated dogs have with humans. This also matches the work showing that dogs are especially good at using human social cues. Hope I’ve helped ;)
Answer:
without choices to choose from, I'd say vaccinations....also herd immunity, and early health screenings.
The right answer is Joints (or ligaments more precisely).
Muscle is the contractile structure that produces strength. It has components that allow it to be shortened to create what is called a muscle contraction.
The joint is junction of two parts of the skeleton allowing them relative mobility.
The ligament is an elastic structure that stabilizes the joints. It therefore attaches from one bone to another.
