ifc 3.1 and 3.4 Theories and Laws in Science

In the context of biology, how does the theory of evolution demonstrate the characteristics of a scientific theory?

• It is a guess about how species change over time.

• It is supported by a wide range of evidence from various scientific fields.

• It is a law that describes the process of natural selection.

• It is a hypothesis that has been tested once.

Consider the theory of evolution by natural selection. What strategic thinking process would you use to evaluate the evidence supporting this theory?

• Memorize the key points of the theory.

• Analyze various forms of evidence such as fossil records, genetic data, and observed evolutionary changes.

• Accept the theory because it is widely taught.

• Compare it to other scientific laws.

How can the distinction between scientific theories and laws be applied to understand the nature of scientific inquiry in biology?

• By recognizing that both are interchangeable.

• By understanding that theories provide explanations and laws provide descriptions.

• By assuming that laws are more reliable than theories.

• By considering theories as unproven laws.

What reasoning would you use to argue that the theory of evolution is a well-supported scientific theory?

• It is based on a single piece of evidence.

• It is supported by multiple lines of evidence from different scientific disciplines.

• It is a law that has been proven.

• It is a hypothesis that has been accepted without question.

In what way does the theory of evolution by natural selection exemplify the culmination of scientific investigations?

• It is based on a single experiment conducted by Charles Darwin.

• It integrates evidence from genetics, paleontology, and comparative anatomy.

• It is a law that describes the survival of the fittest.

• It is a hypothesis that has been widely accepted.

Why is it important to recognize that scientific theories do not become laws?

• Because theories are less reliable than laws.

• Because theories and laws serve different purposes in science.

• Because laws are hypotheses that have been proven.

• Because theories are guesses.

How would you use strategic thinking to evaluate the claim that the theory of evolution is just a hypothesis?

• Accept the claim because it is a common misconception.

• Investigate the extensive evidence and scientific consensus supporting the theory.

• Dismiss the claim without consideration.

• Compare it to other scientific laws.

Do the evolution of our opposable thumbs support Darwin or Lamarck's theories?

• Lamarck

• Darwin

How do fossils support evolution?

• Individual species disappear and reappear in the fossil record over time.

• Organisms in the fossil record are identical to living organisms.

• The fossil record provides evidence that all organisms developed at the same time.

• The fossil record provides evidence that organisms have changed over time.

Which scientist visited the Galapagos Islands, observed traits in finches, and came up with the theory of natural selection?

• Alfred Russell Wallace

• Jean-Baptiste Lamarck

• Carolus Linnaeus

• Charles Darwin
