The BEST explanation why anatoxin-a(s) is described as a peripheral acetylcholinesterase inhibitor (affecting the peripheral nervous system, rather than the central nervous system) is which of the following statements.                        

A 13.2 lb, spayed, 3-year-old  DSH cat exhibiting vomiting, depression, hypothermia, dyspnea, muddy, brownish mucus membranes, chocolate brown-colored blood and urine, with a swollen face and paws (similar to what is shown in the images above) is brought to your clinic. Serum ALT was high. The owner reported that a bottle of Paracetamol pills had spilled onto the floor last night, but she didn’t think that the cat (“Mischief”) could have consumed more than three pills. Assuming the worst case scenario that “Mischief” did consume three of the 500 mg, extra-strength Paracetamol pills you suspect are responsible for “Mischief’s clinical signs, what would the exposure dosage of this pain medication be in mg/kg body weight? NOTE: The toxic dosage for Paracetamol/Acetaminophen in the cat is reported to be as little as 10 mg paracetamol/kg body weight. SECOND NOTE: 1 mg = 0.000035 ounces; 1 kg = 2.2 lb; 1 lb = 16 ounces; and 1% = 10,000 mg/kg of product.

TRUE OR FALSE: The MOST appropriate samples to submit to a toxicology laboratory for toxicology testing are generally fixed in 10% Neutral-Buffered Formalin (NBF).

 Extra Credit (5 pts):  Sally throws a water balloon down from a height of 100 m above the ground. Two seconds later, Jake throws a water balloon straight up from the ground.  At what height above the ground do the two balloons pass each other? (Select closest answer and show ALL work!)

Which  of the figures below depicts the Blood-Brain-Barrier?

A m = 8 kg block on a horizontal frictionless surface is attached to a light spring (force constant = 0.85 kN/m).  The block is initially at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to the surface is applied to the block, as shown.  Starting from the “One Equation to Rule Them All” (the energy equation) and showing all steps, find the speed of the block when it is 13 cm from its equilibrium position.  (Round to nearest answer)

 A 2-kg ball slides on a curved wire, starting from rest at point A.  The segment from A to B is rough (i.e. it has friction!) and the segment from B to C is frictionless.  Find the speed of the ball at B if the ball comes to rest (momentarily) at C. (select closest answer)

Object A, moving to the right, has a one-dimensional elastic collision with object B which is initially at rest as shown. What is the final velocity of object A?
