Question

all of the following statements are true, but only one is an actual claim according to the framework for scientific explanations. choose the answer below that is a claim. (hint: a claim is a one-sentence answer to the investigation question). (1 point) mnca25 moves faster at 31.2 km/s when closer to its star and slower at 28.7 km/s when farther away. mnca25 follows kepler’s laws of planetary motion, just like planets in our solar system. mnca25 has an orbital eccentricity of 0.04, which is close to a circle.

Explanation:

A claim is a one - sentence answer to an investigation question. Let's analyze each option:

• The first option ("MNCA25 moves faster at 31.2 km/s when closer to its star and slower at 28.7 km/s when farther away") is a description of the speed of MNCA25 at different distances from its star, more like an observation or data presentation.
• The second option ("MNCA25 follows Kepler’s laws of planetary motion, just like planets in our solar system") is a claim as it answers the question (implicitly about the motion of MNCA25) by stating that it follows Kepler's laws, which is a general statement about its motion behavior.
• The third option ("MNCA25 has an orbital eccentricity of 0.04, which is close to a circle") is a description of the orbital eccentricity of MNCA25, more of a factual statement about a property rather than a claim answering an investigation question.

Answer:

B. MNCA25 follows Kepler’s laws of planetary motion, just like planets in our solar system.
