An example of potential energy is 1. The air in an inflated balloon.

Potential energy is stored energy. The air in the inflated balloon has elastic potential energy because it is being stored in the ballon. If the mouth of the inflated balloon is released or if the balloon is popped, the potential energy in the balloon transforms into kinetic energy.
All of the other answer choices are examples of kinetic energy or energy in motion. The wrecking ball, boulder, and water are all moving which means that they all contain kinetic energy, not potential energy.

MaRussiya [10]

Answer:

B. Directional selection

Explanation:

When natural selection starts to choose one phenotypes that is an extreme (as in, a really small neck or a really long neck), this is an example of <u>directional selection.</u> It makes sense for giraffes to have evolved this way, because the longer the neck, the more ably they can eat food from high branches. The more food they could get, the more chance of reproduction, the more "evolutionarily fit" they are.

Stabilizing selection is when national selection picks average phenotypes (like a medium-sized neck). Disruptive selection is when the extremes are both picked (like all the medium-sized neck giraffes die, and two different species start to emerge). Sexual selection is picking a mate based on traits. Clearly, those answers don't work here.

What is the difference between an element and a compound?
Marina86 [1]

Answer:

Common examples include carbon, sulfur, oxygen, iron, copper, aluminium. Elements are represented by symbols. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction.

Explanation:

Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.
