Economics
Rise. If the demand for stocks increases, the price goes up. Unless a company offers more shares for sale, there are a limited number on offer. So, as in anything, if the demand is larger than the supply, the price increases.

Think about how the animals you are familiar with get their food. How does a deer get its food? A rabbit? A snake? A lizard? A spider? What about a sea anenome? You know some answers to this question already. As for body plans, you probably know how to answer this in part too:...

Thank you, but I think I have answered my own question. I believe it is e. 1, 2, 3, and 4 because hydrogen bonding causes the melting and boiling point to rise, vapor pressure to fall, and makes the molecules cling together more, therefore higher surface tension. Still, your o...
