The motivation to abstain from adding water to concentrated acids is that, with a few acids, amid weakening, a considerable measure of warmth is discharged, by adding the corrosive to the water, the generally extensive measure of water will retain the warmth. On the off chance that you added water to concentrated corrosive when you initially beginning pouring the water, it could get sufficiently hot for the little measure of water that was filled all of a sudden bubble and splatter corrosive on you. Concentrated sulfuric corrosive is most famous for doing this, not all acids get that hot on weakening, but rather in the event that you make a propensity for continually adding the corrosive to water for every one of them, you can't turn out badly.
A. An octopus
An organism is an individual animal, plant, or single-celled life form.
The octopus is the only living thing listed so that is why it is the example of an organism
The answer is B Covalent bonds
That answer for that question is B
What makes a question scientific is that we are able to test our hypothesis.
For example: Will increased sunlight cause more seeds to grow. We can test that simply by placing seeds in the sun and some out of the sun.
If you cannot test an hypothesis, then it is NOT scientific
For example: Macroevolution isn't a scientific question because we cannot test whether or not complex organisms come from simpler organisms. It can only be classified as an Hypothesis at best.
