Question

Responses

Theories can be modified or discarded in light of new evidence.
Theories can be modified or discarded in light of new evidence.

Theories are well-substantiated explanations of natural phenomena.
Theories are well-substantiated explanations of natural phenomena.

Theories are just guesses and lack substantial evidence.
Theories are just guesses and lack substantial evidence.

Theories provide a framework for understanding and predicting scientific observations.

Answer 1

The FALSE statement among the options is:

Theories are just guesses and lack substantial evidence.

This statement misrepresents the nature of scientific theories. In reality, theories are based on extensive evidence and research, and they provide a well-substantiated explanation of phenomena.

Answer 2

How can technology change a theory?(1 point)
Responses

By providing new tools to gather more precise data and evidence
By providing new tools to gather more precise data and evidence

By changing the scientists working on the theory
By changing the scientists working on the theory

By completely disproving the theory
By completely disproving the theory

By influencing the popularity of the theory

Answer 3

The correct response is:

By providing new tools to gather more precise data and evidence.

Technology can enhance the methods of data collection and analysis, leading to more accurate observations that can support, refine, or challenge existing theories.

Answer 4

Why is natural selection considered a theory in biology?(1 point)
Responses

It involves the formation of all living things on the planet.
It involves the formation of all living things on the planet.

Many scientists all over the world accept it as true.
Many scientists all over the world accept it as true.

There is lots of evidence to support it.
There is lots of evidence to support it.

It deals with topics that may or may not be testable in a laboratory.

Answer 5

The most accurate response is:

There is lots of evidence to support it.

Natural selection is considered a theory in biology because it is supported by a vast body of evidence from various fields such as genetics, paleontology, and ecology. It explains how evolutionary processes occur, and it has been extensively tested and validated through research.

Answer 6

What is the difference between a scientific theory and a scientific law?(1 point)
Responses

A law is applicable only to physical sciences, whereas a theory can be applied to any scientific discipline.
A law is applicable only to physical sciences, whereas a theory can be applied to any scientific discipline.

A theory can never be proven, whereas a law is always proven to be true.
A theory can never be proven, whereas a law is always proven to be true.

A theory is based on extensive experimental evidence, whereas a law is based on theoretical assumptions.
A theory is based on extensive experimental evidence, whereas a law is based on theoretical assumptions.

A theory explains why a phenomenon occurs, whereas a law describes what happens.
A theory explains why a phenomenon occurs, whereas a law describes what happens.

Answer 7

The correct response is:

A theory explains why a phenomenon occurs, whereas a law describes what happens.

In essence, scientific laws summarize observed phenomena and state what happens under certain conditions, while scientific theories provide explanations for those phenomena and often describe the underlying mechanisms involved.
