Question

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

The graph shows Time in days from 0 to 5 on the x-axis and number of seeds versus sprouts from 0 to 100 on the y-axis at 12 drops of water per hour. Day 0 there are 100 seeds and 0 sprouts. Then the number of seeds decreases while the number of sprouts increases starting at 2.5 days. On Day 5 there are 59 seeds and 41 sprouts.The graph shows Time in days from 0 to 5 on the x-axis and number of seeds versus sprouts from 0 to 100 on the y-axis at 50 drops of water per hour. Day 0 there are 100 seeds and 0 sprouts. Then the number of seeds decreases while the number of sprouts quickly increases starting at 2.5 days. There are an equal number of seeds and sprouts before Day 3. On Day 5 there are 2 seeds and 98 sprouts.The graph shows Time in days from 0 to 5 on the x-axis and number of seeds versus sprouts from 0 to 100 on the y-axis at 72 drops of water per hour. Day 0 there are 100 seeds and 0 sprouts. The number of seeds quickly decreases while the number of sprouts quickly increases starting at 2.5 days. On Day 3 there are an equal amount of seeds and sprouts. On Day 5 there are 33 seeds and 67 sprouts.The graph shows Time in days from 0 to 5 on the x-axis and number of seeds versus sprouts from 0 to 100 on the y-axis at 90 drops of water per hour. Day 0 there are 100 seeds and 0 sprouts. The number of seeds quickly decreases while the number of sprouts quickly increases starting at 2.5 days. On Day 3 there are an equal amount of seeds and sprouts. On Day 5 there are 33 seeds and 67 sprouts.
a.
90 drops/hr
b.
72 drops/hr
c.
50 drops/hr
d.
12 drops/hr

Answer 1

C. 50 drops/hr

Step-by-step 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.

Answer 2

C. 50 drops/hr

Step-by-step 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.
