3. In science, a theory is more like a scientific law than a hypothesis. A theory
explains a set of observations or events. It must be verified multiple times by
many different scientists. One scientist cannot create a theory on his or her own.
a) Look back at your hypothesis from question 2. Could this hypothesis become
a theory if you repeated your experiment 100 different times and got the same
results? Can a theory be created by just one person? (2 points)
Answers
Answer:
No
Explanation:
A theory cannot be made by one person, no matter how many times they repeat the experiment. Therefore, you repeating the experinment does not make it a theory. The experinment must be repeated by others and get same result as you to confirm it as theory.

Tree squirrels can have different fur colors.
Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur the same color as the trees are harder for the foxes to see and catch.
[IMAGE ONE]
The diagram above shows a population of squirrels that lived in a forest. Scientists had previously only seen brown and gray squirrels in this forest; they had never seen squirrels of any other color.
The diagram below shows how the population changed after many generations.
[IMAGE TWO]
How did the color of the trees in the squirrels’ environment change? Explain what happened to the squirrels over many generations.
Answers
Answer:
The gray squirrels were easy to see and catch so they died quickly and the population dwindled. The brown squirrels were probably almost the same color as the tree so they were harder to see and catch. The remaining gray squirrels ended up having no other options than to mate with brown squirrels, which probably made appear black squirrels and since the black squirrels population raised, means they are harder to see and be caught by foxes.
How the trees became more black too? I have no idea, sorry.
