Using the graphs below, determine which water drop rate leads to the highest seed growth.

expeople1 [14]

Answer:

C. 50 drops/hr

Explanation:

As we can see in the description of the graph above, 50 drops/hr was the rate of water fall that was most successful in plant growth. This is because with this rate, the seeds germinated more quickly, the seedlings showed a strong and fast vegetative growth, besides that at the end of 5 days, it was observed that germination of almost 100% of the seeds occurred. These facts cannot be observed with the other waterfall rates, so the correct answer is 50 drops/hr.
