A- ECOLOGY
Explanation:
Ecology is the study of how organisms interact with one another and with their physical environment.
The distribution and abundance of organisms on Earth is shaped by both biotic, living-organism-related, and abiotic, nonliving or physical, factors.
Ecology is studied at many levels, including organism, population, community, ecosystem, and biosphere.
Many motor units in a muscle are stimulated in quick succession. The most likely to happen is that the contractions will produce tetanus.
A motor unit is made of a motor neuron and the skeletal muscle fibers innervated by that motor neuron's axonal terminals. A group of these motor neurons work together to coordinate the contraction of a single muscle. During a concentric contraction, a muscle is stimulated to contract according to the sliding filament theory, which occurs throughout the length of the muscle, therefore, generating a force at the origin and insertion, causing the muscle to shorten and changing the angle of the joint.
