Question

silkworms are raised commercially for the silk cocoons that they produce. in ten different trials, jamis class raised silkworms under different temperatures to see what conditions are best for silkworm caterpillars in their first three instars or stages. in each trial, they began with 30 silkworm eggs. the table below shows the data jami recorded. trial number temperature (°f) number surviving to adulthood 1 55 0 2 60 1 3 65 1 4 70 3 5 75 6 6 80 12 7 85 26 8 90 19 9 95 7 10 100 0 which statement below does the data support? a. too much heat or too little heat is bad for the growth of silkworms. b. silkworms can grow successfully at any temperature. c. ninety degrees is the perfect temperature for growing silkworms. d. temperature is not a condition that affects the survival of silkworms.

Explanation:

Analyze the data in the table. At low temperatures (55°F) and high temperatures (100°F), the number of silkworms surviving to adulthood is 0. As temperature increases from 55°F to 85°F, the number of survivors generally increases, then decreases at 90°F - 100°F. This shows that extreme temperatures are bad for silkworm growth.

Answer:

A. Too much heat or too little heat is bad for the growth of silkworms.
