Answer:
Her knee ligaments are weakened or injured so they can't stabilize the bones
Explanation:
Ligaments are dense connective tissues that serve to connect bones to each other. Ligaments are made by definite arrangement of collagen fibers in particular pattern. Weakening or injury to ligament makes the joints unstable. Since ligaments are not strong enough to hold the bones together, weakened or injured ligaments lead to bone dislocation. The woman with complaint of regular bone dislocation in her left knee must have weak or injured ligaments that can’t stabilize the bones.

The correct answer for this question is letter C. Epiglottis is the one who prevents food from entering the trachea. It moves in a back and forth manner. When a person swallows, it covers the entrance of the larynx by flattening itself backwards.
We can’t predict what will happen when a predator is lost from an ecosystem; there are too many unknown ways that species interact, and the processes take place over scales of tens to thousands of square kilometers. The true effect of a loss can’t be known until years or decades after it has taken place.
