Plants have internal transportation systems that help move food, water, and minerals through the plant. The plant's food, sugar, is produced by the leaves of the plant. Water and minerals are absorbed by the roots. The following diagram is a model of the transportation systems in a plant.

What is one advantage of using this model?
A.
It clearly shows the general directions that food, water, and minerals must move.
B.
It gives a complete picture of the methods used to transport resources to all parts of the plant.
C.
It has parts that are the same size and shape as the components they represent.
D.
It provides details about the ways that the transportation systems work with other parts of the plant.

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
