Your experiment has an accurate outcome. The only variable that should be changing is what you have already determined to be the independent variable. All other variables must be controlled (sometimes called constant) in order to preserve the accuracy of the experiment and ensure that the only thing impacted the change in the dependent variable is directly caused by the independent variable.

Vesna [10]

You may be talking about change from rapid-acting insulin to intermediate-acting insulin. Rapid acting insulin, as it implies, has onset of 10 to 30 minutes and peaks in 3 hours. Meanwhile, the intermediate-acting insulin takes 1 hour and 30 minutes to 4 hours to take effect, and it peaks in 4 to 12 hours. If changing from rapid-acting to intermediate-acting, there is a big space where there might be no insulin in the body to control blood sugar levels. As a nurse, you should carefully monitor blood glucose levels every 30 minutes and watch out for symptoms of hypeglycemia.

Dima020 [189]

Answer:

b. It is converted to heat.

Explanation:

Cellular respiration is the process of energy transformation. During this process, the chemical energy present in the chemical bonds of glucose molecules is first stored in the form of NADH and FAD2. Then the same is used to drive the process of ATP synthesis during oxidative phosphorylation. Each process of energy transformation loses some of the energy in the form of heat to the surroundings. The lost energy can not perform any function. Therefore, part of the energy of glucose is also lost in the form of heat as the process of cellular respiration follows the laws of thermodynamics.
