The correct answer is A. It should be recorded in milligrams

Explanation:

In an experiment, one of the most important elements is the units used to measure substances, because these are different depending on the substance, and the purpose of the experiment.

In the case presented, it is correct Alai decided to use milliliters to measure the volume of water because the milliliter (mL) is a unit that measures the volume of liquids. However, he cannot use milliliters to measure the mass of salt because milliliters measure volume rather than mass. Instead, he should use milligrams as this measure mass of the substance and similar to milliliters is appropriate for small quantities of a substance. Thus, Alai's salt measurement is wrong because it should be recorded in milligrams.

e-lub [12.9K]

The function of the limb is to help them get around and move. They might be similar in the way they’re structured? I don’t have a picture so I can’t tell. And you can assume that at one point these four animals all shared a common ancestor. Hope I helped!

Do you think it is possible to have the benefits of the agricultural & industrial revolution without the environmental costs

telo118 [61]

I do not think the industrial and agricultural revolutions could have occurred without the environmental costs. The industrial revolution in the 18th century occurred at a time in history when people where not aware of the consequences of their actions or the consequences of the widespread use of fossil fuels. Even if they were aware the technology would not have been present to harness power from natural renewable sources of energy.
