The deep blue color of the starch and iodine solution disappears when it reacts with saliva. which of the following best explains the rate of disappearance of the color when the substances in the test tubes were mixed? faster in bath 1 as molecules

amylase breaks down carbohydrate (starch) .

Explanation:

Iodine is a dimer molecule and when it reacts with starch which is a glucose, it forms deep blue color. In the presence of amylase a digestive enzyme which breaks down starch, comes in contact with the solution, it breaks down the carbohydrate and iodine polymer chains are broken down, and the [blue/black] color disappears.

This experiment is used to test the effect of digestive enzymes on foods (carbohydrates) in this case.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
