Answer the following question given this paragraph: One way mammals lose excess heat is by increasing blood flow to the skin. This warms the skin so heat can be given off to the environment. That's why you may get flushed, or red in the face, when you exercise on a hot day. You are likely to sweat as well. Sweating also reduces body heat. Sweat wets the skin, and when it evaporates, it cools the body. Evaporation uses energy, and the energy comes from body heat. Animals with fur, such as dogs, use panting instead of sweating to lose body heat (see Figure below ). Evaporation of water from the tongue and other moist surfaces of the mouth and throat uses heat and helps cool the body. Q: How do dogs lose body heat? Choices: - barking - sweating - eating - panting A:
panting

Ques:Answer the following question given this paragraph: The standard cell potential is positive, so the reaction is spontaneous as written. Tin is oxidized at the anode, while silver ion is reduced at the cathode. Note that the voltage for the silver ion reduction is not doubled even though the reduction half-reaction had to be doubled to balance the overall redox equation. Q: Tin is oxidized at the anode, while silver ion is reduced at? Choices: - anodyne - iodine - gamma - cathode A:

Ans:cathode
