I think it’s c I’m not very sure
I think the correct answer from the choices listed above is option A. The anatomical adaptation which helps an elephant regulate its body temperature are its large ears increase surface area so that more heat is lost by radiation. Heat can be released as they flap these ears. So there is your correct answer
potential energy
you have potential energy when you're stopped. you have kinetic energy when you're moving. so as you're going down a hill, kinetic energy is increasing and potential energy is decreasing.
Arteries like veins, are tube-shaped vessels that carry blood in the body.
But the difference is that the artery carries oxygenated blood away from the heart to the body. But the veins carry poor-oxygen blood back from the body to the heart!
I hope this helps! :)
