Answers:
1. C. Red-eyed tree frogs can NOT kill other creatures with their venom, because they are not venomous.
2. B. Polar bears' blood cells have extra oxygen.
3. False, chimpanzees transmitted SIV to humans (forming HIV).
4. C. venous blood cools arterial blood via heat exchange
5. False, little mixing does occur, but it doesn't greatly decrease the amount of oxygen needed to supply the rest of the body.
6. E, A and O blood types
7. True
