Which statement is true? (1 point)
• As evidence changes, scientific theories can also change.
• Scientific theories only involve finding evidence to explain phenomena.
•
Scientific theories describe natural phenomena, whereas scientific laws explain natural phenomena.
O If a single study or inference is wrong, a scientific theory can be invalidated.

While studying in the lab, a scientist discovers that a sample of platypus fur glows blueish-green under ultraviolet light. When would the scientist have enough evidence to propose a theory? (1 point)
• The scientist would need to publish a paper detailing their results in a trusted journal.
• The scientist could propose a theory based only on this initial study.
The scientist could propose a theory after briefly examining samples of other species.

The scientist would need to study many samples of different species over several generations to get enough evidence to propose a theory.

• Jose explained that all planets orbit around the sun in an elliptical path.
• Ada predicted the distance a soccer ball traveled when kicked at a certain angle.

Use the following statement to answer the question.
Evolution happens due to natural selection, a process in which organisms that have the genes that are more suited to an environment survive. They pass on their traits to the next generation.
Is this a scientific law? Why or why not?
(1 point)
• No, this statement is supported by evidence that comes from experimentation and observations.
• No, this statement explains how evolution occurs.
• Yes, this statement describes how evolution occurs, but does not explain how.
• Yes, this statement is true.

What could happen if a scientist discovered new information concerning a scientific theory? (1 point)
• The new information could be used to create another, slightly different theory.
Nothing would change since laws and theories have similar components and are interchangeable
• The new information could be used to change the theory into a law.
• Nothing would change since laws and theories have completely aifferent components and are-not interchangeable.

The true statement is:

• As evidence changes, scientific theories can also change.

Scientific theories are based on evidence and can be revised or refined as new evidence emerges.

The correct answer is:

• The scientist would need to study many samples of different species over several generations to get enough evidence to propose a theory.

A theory in science is developed based on a substantial body of evidence and replication of results across multiple studies and contexts, rather than relying solely on initial observations or a limited set of data.

The statement that best describes a scientific theory is:

**Eva explained that two brown-haired parents had a child with red hair due to dominant and recessive genes.**

This statement reflects an explanation based on the principles of genetics, which is a foundational aspect of scientific theories. Scientific theories provide comprehensive explanations of phenomena that are supported by substantial evidence.
Answered by GPT-4o mini
The correct answer is:

**No, this statement explains how evolution occurs.**

A scientific law describes a consistent and universal relationship observed in nature, often expressed in mathematical terms. In contrast, this statement explains the mechanism of evolution (natural selection), which is characteristic of a scientific theory rather than a law.
Answered by GPT-4o mini
The correct answer is:

**The new information could be used to create another, slightly different theory.**

If a scientist discovers new information that challenges or adds to an existing scientific theory, it could lead to modifications of the current theory or the development of a new, more refined theory that better explains the observed phenomena.
