Question 2

In an experiment, a student rolls a ball down a ramp and measures how far it travels on a flat surface. What does Newton's First Law predict about the ball's motion on a frictionless surface?

Accepted Answer

It would continue moving at constant speed indefinitely

Answer

Question 3

Which process in the water cycle involves water vapor cooling and turning into liquid water droplets that form clouds?

Accepted Answer

Condensation

Answer

Condensation occurs when water vapor in the atmosphere cools enough to change into tiny liquid droplets, forming clouds and fog.

Question 4

A chromosome is made of tightly coiled DNA. What is the primary function of DNA in a cell?

Accepted Answer

To carry genetic instructions for building proteins and traits

Answer

DNA contains the genetic code — sequences of base pairs that serve as instructions for making proteins and determining inherited traits.

Question 5

Two substances are mixed together and produce a gas, change color, and release heat. What type of change has occurred?

Accepted Answer
