Bio 182 Modules 5 and 6 Questions and Correct Answers Which group is not a population? A. People B. Bacteria C. Giant pandas D. Bark scorpions E. All four groups are populations Answer - E How would you estimate the number of whales in a population? Answer - Mark and recapture True or False? Sampling quadrants would be the better method for estimating the number of whales in a population. Answer - False; by putting down little sub -samples and counting how many whales are in there, those whales could leave and swim somewhere el se so that when you put a quadrant down somewhere else, that same whale might have come up again as they are mobile organisms. Therefore, mark and recapture would be a better method for estimating the number of whales in a population. True or False? Mark and recapture would be the better method for estimating the number of saguaros (cacti) in a population. Answer - False; unnecessary because these plants don't move. Sampling would be a better method for non -mobile organisms. True or False? The shrinking population between 1965 and 1970 could have resulted from a decrease in the birth rate or an increase in the death rate. Answer - True; it "could" be either of these. True or False? The growing population between 1985 and 1995 could have resulted from a decrease emigration or an increase in immigration.
