Answer:
Carbon atoms
Explanation:
Mass no. of an element= no. of protons + no. of neutrons = 6 + 7 = 13
Atomic no. = no. of protons/electrons = 6
There is an unbalanced situation between the neutron no and proton no. so this has to be an isotope of Carbon-12, and this element is Carbon-13.
wouldn’t the independent variable be just the student who are asked to sign in? Because, isn’t the independent the one that is being changed and the dependent variable is the one responding to the change?
- A dependent variable is the variable that changes as a result of the independent variable manipulation. It's the outcome you're interested in measuring, and it “depends” on your independent variable.
The most likely toxic chemicals that is found in baby bottles is called BPA. If high doses of this chemical is consumed, it might shut down the response system of estrogen in the babies. It could also possibly change the babies ability of producing ordinary thyroid hormones.
Law makers can address this possibility by making a law that bans the creation of a baby bottles plastic that contains these toxic chemicals. This provides with a strict interpretation of the precautionary principle because it is ‘banning’ all the bottles plastic that contains toxic chemicals. Banning is a strict interpretation.
Law makers can also make a law that limits the doses of this toxic chemical that can be found in the bottles plastic. This is a strict interpretation because there is a limit, and if the producers go above the limit, there is consequences to face.
