Reflexes are a part of the body's defense mechanism.

Reflex is not necessarily a form of negative feedback response. Reflexes are quick, involuntary responses to stimuli, while negative feedback is a regulatory mechanism that helps maintain homeostasis by reducing the effects of any deviation from an ideal set point. Reflexes can be part of negative feedback loops, but not all reflexes are negative feedback responses.
That is simply part of your defense mechanism. Your body generally doesn't want you to die.

The medulla oblongata is a part of the brain stem involved in these reflexes. And no your eyes will not pop out if you sneeze with them open. Closing the eyes is part of the reflex and you have no control over reflexes.

Leaf size is not typically a part of defense mechanisms in plants. Instead, defense mechanisms often include thorns, spines, chemical toxins, and mimicry to deter herbivores or pathogens. Leaf size is more related to factors like photosynthesis and resource allocation.
The part of the cell membrane that acts as a defense mechanism in recognizing viruses is primarily the protein receptors. These receptors can detect specific viral proteins or other pathogen-associated molecular patterns (PAMPs) on the surface of viruses. Upon recognition, the cell can initiate immune responses, such as signaling pathways that lead to the production of antiviral proteins or the activation of immune cells, thereby providing a defense against the invading virus.
