The correct answer is: tighten and contract
This is is the correct
answer because muscle fibers need to first reach an optimal length and
tension ratio or "tighten" in order for the muscle to perform work.
After the muscle has tightened, it can then "contract" which leads to a
decrease in the angle of the joint through force. If the muscle being
used to pull the rope is the bicep on the arm, then the angle between
the forearm and upper arm will decrease, causing the rope to be pulled.

Answer:
1.) The food or drink enters the mouth and sits on the taste pores on the surface of the tongue.
2.) The chemical molecules dissolve and become tastants.
3.) The tastants go to the taste receptors (that are located within the taste buds and papillae) via the gustatory hairs.
4.) The tastants stimulate the taste receptors.
5.) The taste receptors convert the tastants into sensory information that can be sent to the brain.
6.) The sensory information travel on the neural pathways along the facial cranial nerve.
7.) The sensory information goes to the thalamus.
8.) The sensory information goes to the primary gustatory cortex for interpretation.
