Answer:
The second option.
Explanation:
We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.
The 2nd option uses different amounts of bleach to clean the same amount of stain.
If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.
It's not an effective way to see if the amount of bleach has an effect on stain removal.
B because B is the nucleus which is the storage location of DNA
Answer:
C. 50 drops/hr
Explanation:
As we can see in the description of the graph above, 50 drops/hr was the rate of water fall that was most successful in plant growth. This is because with this rate, the seeds germinated more quickly, the seedlings showed a strong and fast vegetative growth, besides that at the end of 5 days, it was observed that germination of almost 100% of the seeds occurred. These facts cannot be observed with the other waterfall rates, so the correct answer is 50 drops/hr.

Answer: 2 - The nucleus of an atom is split apart
Explanation: Any reaction involving the nucleus of an atom is called a nuclear reaction. It is different from ordinary chemical reactions that involve electrons because it involves the release of large amount of energy. Nuclear reactions can be classified as nuclear fission and nuclear fusion.
A nuclear reaction in which a nucleus of an atom is split into two smaller atoms with a release of large amount of energy is called nuclear fission. A nuclear reaction that involves the combination of lighter nuclei of elements to form heavier atoms that are more stable with the release of a large quantity of energy is called nuclear fusion.
