Question 12 of 14

Which of the following statements BEST describes bioconcentration?

(A) Accumulation of substances or other organic chemicals in an organism from all sources (water, food, air, and so on)

(B) Bioconcentration occurs when an organism absorbs a toxic substance at a rate greater than at which the substance is lost from all sources (water, food, air, and so on)

(C) Bioconcentration refers to the uptake and accumulation of a substance from water alone

(D) All of the above

Question 13 of 14

(C) Stomach cancer

Question 14 of 14

The coefficient of correlation for two variables is 0.95 and is significant at the 2% level. This indicates that:

(A) There is almost a positive linear relationship between the two variables and there is a 2% probability that the coefficient of correlation resulted from chance.

(B) There is almost a positive linear relationship between the two variables but there is a 98% probability that the coefficient of correlation resulted from chance.

(C) There is almost an inverse linear relationship between the two variables but there is a 2% chance that the coefficient of correlation resulted from chance.

(D) There is almost an inverse linear relationship between the two variables but there is a 98% probability that the coefficient of correlation resulted from chance.
