On a hot day, an endotherm may give off more heat by increasing blood flow to the surface of the body. If Jim is an endotherm would his body give off more or less heat if the blood flow to the surface of his body were decreased?
less

(Answer)
higher

Ques: If the gas is cooled, the particles will move more slowly, because they will have less energy. If Jim decreases the amount of energy inside of a gas, the particles in the gas will move more or less?
Ans: less

Ques:Greater use of oil and other fossil fuels causes more pollution. Mike is looking at two cars to buy. The first car, a Toyota, uses twice as much oil and fossil fuels to run, compared to the Kia he is looking at. If Mike wants to buy the car that causes less pollution, he should buy the Toyota or Kia?

Ans:Kia

The size of the eroded particles depends on the velocity of the water. Eventually, the water deposits the materials. As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited. Mike wants to see how fast water can run while not depositing small particles. In order to avoid get the smaller particles deposited, Mike will need the water to be running quickly or slowly?
quickly
