Explanation:
A keystone species is an organism that helps define an entire ecosystem. By keeping populations of mussels and barnacles in check, this sea star helps ensure healthy populations of seaweeds and the communities that feed on them—sea urchins, sea snails, limpets, and bivalves.
"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.
The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.
Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.
The triceps brachii has four places of attachment: three origins and one insertion on the ulna (two on the humerus and one on the scapula).
