Shells evolved from ribs. ... Turtles and other shelled creatures use shells like shields to protect themselves from predators, or animals that hunt them. Turtles probably needed a shield on their backs and stomachs because they faced predators in the ocean from both above and below.
Answer: Every day, we make hundreds of choices.
Explanation: We choose what to wear, what to do when we get home from work or school, and how to respond when someone makes fun of us. Sometimes we also make big decision, such as what kind of school to go to, what career to pursue, whether to get married, and whether to have a child. Sometimes people make decisions that are even bigger than these because the decisions affect hundreds or millions of people - decisions about war and peace or about changes in the laws. Even if we ourselves don't make such big decisions, we need to understand how they are made. Most of the time, we make these choices without thinking. For small, routine choices such as how to respond when your friend starts a conversation with you, you do not need to think. You have learned how to talk and how to behave in a friendly way without thinking at all, and your habits serve you well. You could behave differently than you do, of course, but your behavior is probably fine as it is. In other cases, though, you THINK about your decisions, from what to wear in the morning to how to spend your money. Sometimes people make choices without thinking when they really ought to think a bit. For example, we sometimes say things that hurt people's feelings and then we feel bad for having said them. Can you think of other examples of things we do because we didn't think first? WHEN it is worth thinking about decisions and, mostly, HOW to think about them once you start thinking. It will teach by example. You will be given a problem about decision making. First, think about the problem and try to answer it. You can discuss the problem with someone else. Then turn the page and look at the answer carefully. Where do these answers come from, and why are they right? The answers come from a field of study called decision theory. It is taught in colleges and graduate schools. It is sometimes used as a way of making very important decisions such as whether to have surgery or where to locate an airport. People who study decision theory and write about agree about some things and disagree about others.

Explanation:
Answer:
The first step is to develop a healthy mental image of meeting new people. Some of us see meeting new people as a scary event. We are concerned about making a good impression, whether the other person will like us, how to keep the conversation going, and so on. The more we think about it, the scarier it seems. This initial apprehension develops into a mental fear, which takes a life of its own and unknowingly blocks us from making new friends. Shyness toward others is actually a result of fear.
Actually, all these fears are just in our head. If you think about it, 99% of people are too busy being concerned about these very things themselves to pay attention to you. While you’re worried about the impression you make, they are worried about the impression they will make. Truth be told, they are just as scared as you are. The remaining 1% are people who recognize that a relationship is built on way stronger values than specific words or things said/done during just one encounter. Even if there are people who do judge you based on what you do/say, are these people you want to be friends with? I think not.
