Answer:
As per the data provided, the correct answer would be cherries.
The effect of any food in increasing the blood sugar level can be understood with the help of glycemic load. It takes in the account of both the glycemic index as well as serving size.
It states that the glycemic response of our body depends on both "the type of carbohydrate and the amount of carbohydrate" consumed in a meal.
For example, glycemic response of small size high GI food is the same as that of large size low GI food.
It can be calculated as follows:

Hence, glycemic load of apple would be = (38 x 17)/100 = 6.4.
Similarly, glycemic load of cherries, oranges, and watermelons would be 4.18, 10, 8.6 respectively.
Hence, cherries are the fruit which has low glycemic load value of 4.18. So, the glycemic response of this fruit would be low. Hence, it will result increase the blood sugar by the least value.
Mammals do; I'm in my science class
To determine the reason for the fish death, do the following:
1. Test the water for the presence of organic substances that may be poisonous to the fish.
2. Test the dissolved oxygen concentration of the lake at different locations and at different depths.
3. Perform full toxicological examination of the lake to determine if any pollutant or poisonous chemical is present in the lake.<span />
