a. yes, two

b. yes, 3 replicates

c. no, there are no replicates

Figure 5. The sex ratio of quail offspring produced following three hormone treatments: oil (n=22), 0.25mg progesterone (n=18) and 2mg progesterone (n=16). The effect of progesterone dose on sex is significant.

2) Does the study include replicates, if so how many?

a. yes, three

b. yes, 22, 18, 10

c. no, there are no replicates

• Daphnia magna Daphnia sp Number of individuals/L 1 2 3 4 5 6 7 8 9 10 11 Days Figure 2. Mean population density (11 standard deviation) of two species of Daphnia following artificial eutrophication of a small farm pond by application of organic fertilizer. Six replicate 1 L water samples were drawn from 50 cm depth at 1100 hr each day. Figure 6. Mean density of Daphnia populations following eutrophication of a small pond near Sacramento, CA. Each day, six IL water samples were collected from the pond from 1-9 days after eutrophication, and the number of daphnia were counted by hand. Means standard deviation are presented for samples collected each day

c. no, there are no replicates

Answer 1

1) for fig 2

answer: yes, 3 replicates. It has replicates which is apparent from the fact that there are error bars. The fact that there were 3 replicates is from the fact that in the Figure legends it is mentioned that 6 replicates of water were collected, 3 for each species.

2) for fig 5

answer : there are no replicates. This is apparent from the fact that there are no error bars
