Answer: Option B
Explanation:
Usually in scientific experiments, at least one parameter is checked; here, the growth rate of wheat in two different conditions is being evaluated.
Hence, growth rate of wheat alone in pans A, B and C becomes the standard or referential control against which the experimental control (Wheat + clover) in pans D, E and F is evaluated, since both treatments are exposed to the same external conditions.

Answer:
Water is polar and oil is nonpolar so the substances won't mix.
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water.

Explanation:
220 + 108 + 25 + 178 + 550 +31 + 41 = 1153
Basically, you take the number of each natural disaster plus it all together. That is your total.
You then take individually the number and divide it by the total (1153), once you get a decimal number you times it by 100. Which give you the percent
You then do this for the rest of the other natural disasters.
