Answer:Answer:

For 1: The correct answer is Model 1, 2, and 4.

For 2: The correct answer is Option 1.

Explanation:

For 1:

Atomic number is defined as the number of protons or number of electrons.

Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.

Answer:

A control variable is the variable in the experiment that does not change.

Explanation:

If you are testing how seeds grow in different types of water, and you add 1tbps of salt to one pot of water with the plant, and then added 2tbps to another pot of water with the plant. The control variable in this experiment would be the water with no salt because it was not altered.

FYI I did not pull from google. Good luck!
