Archaeologists ask questions and develop hypotheses. They use evidence to choose a dig site, then use scientific sampling techniques to select where on the site to dig. They observe, record, categorize, and interpret what they find.
A food resource disappears in a pond, and some frogs in a population can eat the remaining food source, while others cannot.
Explanation:
The natural selection among a species occurs when there are some major changes in the environment, most often related to the availability of food sources. In that kind of a situation, some of the individuals will be able to survive and use the remaining food sources, while some not. The ones that will be able to survive will be the stronger and more adapt.
In this scenario, we have a food resources disappearing from the environment of the frogs, so a food shortage occurs. The frogs that are stronger and able to consume the remaining food sources will be the ones that survive, while the weaker ones will be die out. This will result in a natural selection where only the best individuals of the species survive and reproduce in the given circumstances.
Factors that prompt natural selection are:
- changes in the food sources
- climate changes
- major natural hazards
- destruction of the habitat
- increased competition from other species

<span>Confucianism is a set of philosophical beliefs in how to live that emphasizes family and social harmony. It is at its core humanistic and not spiritual. One of its core beliefs is that people are generally good and that they can be taught and improved through personal and communal endeavors.

C. Family obligations are important.
* TRUE. Obligations to others need to be fulfilled. And family obligations are the most important of all.
D. The key to good behavior and good government is concern for others.
* TRUE. If you're concerned about others more than yourself, then your actions will automatically be for the greater good of society.
E. Laws are the basis of an orderly society.
* FALSE. There should be no need to creating laws upon more laws if everyone is already working towards the greater good. Laws are more useful for indicating to people without a moral foundation as to actions they should or should not take. But if you have a solid moral foundation, laws are superfluous.</span>
