Question
P)
What is the difference between the following 2 statements?
Statement A: The finches on the Galapagos Islands, which have different beak shapes
adapted to their specific diets, exemplify how species can evolve distinct traits in response to
their environment.
Statement B: The gravitational attraction between the Earth and an apple, which causes the
apple to fall from a tree to the ground, is expressed by Sir Isaac Newton's description of the
gravitational force between two objects.
(1 point)
Statement A is a law and Statement B is a theory.
Statement A is a theory and Statement B is a law.
Both statements are scientific laws.

Q) What evidence would have been needed to refute the theory of gravity before it was proven
to be a law? (1 point)
Discoveries that gravitational forces only act on objects in space, not on Earth.
Evidence that the gravitational force is stronger at higher altitudes than at sea level.
Observations showing that objects of different masses fall at the same rate in a vacuum.
Experiments demonstrating that objects do not accelerate towards the Earth when dropped.

### P) Difference between the statements:
The correct distinction is: **Statement A is a theory and Statement B is a law.**
- **Statement A** describes the concept of evolution, which explains how species adapt their traits over time based on environmental pressures. This is a scientific theory because it provides an explanation for observed phenomena.
- **Statement B** describes the law of gravity, which states that objects attract one another with a force that depends on their masses and the distance between them. This is a scientific law as it describes a consistent, measurable relationship observed in nature.
### Q) Evidence to refute the theory of gravity:
The correct answer is: **Experiments demonstrating that objects do not accelerate towards the Earth when dropped.**
- Discoveries showing that gravitational forces only act on objects in space (not on Earth) would contradict established observations.
- Evidence that gravitational force is stronger at higher altitudes than at sea level contradicts the current understanding but does not refute gravity as a whole.
- Observations showing that objects of different masses fall at the same rate in a vacuum actually support the theory of gravity rather than refute it.
### R) Part of the scientific method that leads to changes in a theory:
The correct answer is: **Results.**
- Results from experiments and observations are crucial as they provide the data that can support or contradict a theory. If results consistently contradict a theory, it may lead to revisions or changes in that theory.
