Birds in a desert climate survive on soft parts of cactus. Scientists observed that during a drought, manyof the birds died. The ones that survived had larger beaks and were able to crack open and eat hardseeds that would ordinarily not be used. What trait would you expect to see in the next generation?

Answer:

Larger beaks. This question refers back to Darwin's theory of Natural Selection. "Survival of the fittest" if the birds that had small beaks all died, the only birds that would be left would be the ones with large beaks.

The outer layer of the Earth is  divided into plates that move  due to convection currents under the surface. theoryFor every action or force  in nature, there is an equal  and opposite reaction. law A hypothesis is a scientific conjecture, not verified that requires corroboration. It is a possibility, but not a fact.  A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relation between variables. It must be objective. The researcher suggests a hypothesis in order to predict what is going to happen. There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.   A law is an affirmation based on repeated experimental observations, it is not that might describe one aspect of a natural phenomenon. This means that it is corroborated by facts, and not only by logic. There is a relation cause-effect.  The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions.  The theory is fundamental to science because it allows scientists to organize and understand observations.  The construction of a theory begins with a hypothesis. The scientist believes that a certain phenomenon occurs in a certain way and so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations as well as of the empirical data collected might derive in a scientific theory that can explain the analyzed phenomenon.  A scientific theory is a knowledge that was contrasted in several ways.
