A group of biology students conducted a lab to study the effect of water on plant growth. They used the following procedure:

1 – Germinate nine bean seeds.

2 – Put three bean plants each into three identical pots containing the same weight and type of soil. Label the pots A, B, and C.

3 – Place pots in an area where they can receive the same amount of sunlight.

4 – Each day pour 30 mL of water into pot A, 20 mL of water into pot B, and 10 mL of water into pot C.

5 – Measure and record the height of the plants every other day for 15 days.

Recorded data:

Which was a limiting factor for this experiment?

(a) one fin is spiny, the other is smooth ® 3 (b) one fin is not spiny or smooth ® 4 5. (a) has small fin on back near tail ® 6 (b) has no fin on back near tail ® 7 6. (a) has barbs near the mouth ® catfish (b) does not have barbs near the mouth ® 10 7. (a) tail is asymmetrical ® 8 (b) tail is symmetrical ® 9 10. (a) scales are small ® trout (b) scales are large ® whitefish what is the next step to complete to identify a fish that has a single dorsal fin, no fin on the back near the tail, and no barbs near the mouth? step 2 step 5 step 7 step 10
