What mechanism causes the painful sores associated with herpes infection?

Black widow anti-venom is produced by injecting small amounts of the actual venom into horses. Several days after the first injection, the horse begins to produce antibodies against the venom. Later, more venom is injected to the animal, and exponentially more antibodies are quickly produced.  These antibodies can be harvested from the blood and used to treat bite victims. The medication is rarely used, however, as it carries a risk of causing an allergic response in humans who react to the proteins from the horse.  Injecting the horse with actual black widow venom produces what kind of immunity?

Which clinical pattern best fits chronic bronchitis rather than emphysema? 

    The graph below describes the motion of an object moving along the x-axis: For the following questions, express intervals using two letters (such as AB). The positive direction (+) points to the right. Then provide a very brief explanation why you are picking these intervals. If the vertical axis represents position, identify all intervals: (a) when the object is moving to the left.(b) when the object is slowing down. If the vertical axis represents velocity, identify all intervals: (c) when the object is moving to the right.(d) when the object is speeding up.
