Answer:
The correct option is C. Motor neuron does not fire action potentials
Explanation:
During contraction, the motor nerve passes down an action potential. A neuromuscular junction is formed by the motor neuron which stimulates the entry of calcium ions. The calcium ions bind to structures called as troponin which stimulates the binding of the filaments, actin and myosin. The filaments begin to contract by using ATP.
During relaxation, the action potential is stopped. Calcium is taken back into the sarcoplasmic reticulum. As a result, actin and myosin filaments do not link and hence, the contraction is stopped.
Carrying capacity of a biological species in an environment is the maximal population size of the species which the environment can be sustained- given the necessities of water, habitat & food and others are available in the environment.
Integrating plant crops and livestock is accomplished by managed grazing. It is a widely used technique.
<h3>What is managed grazing?</h3>
Managed grazing refers to the technique for controlling the intensity of grasses by using different animals.
This technique (managed grazing) uses animals to eliminate mature grasses but maintains the development of new grasses.
Managed grazing is a methodology used to control livestock density, as well as the intensity of grazing.
