If iodine solution reacts with starch, it will change color
into black.
If iodine solution is put on the fruit, according to the coloration, it can be concluded if there is starch in the fruit or not. If the yellow-orange iodine solution stayed the
same color when it was put on the fruit, it can be concluded that there is
no starch in the apple. On the other case, the black color of the fruit suggests that there is a great amount of starch in the potato. What is actually detected is alpha-amylase.
<span>Alpha-amylase breaks down starch into di- and
trisaccharide. If iodine solution reacts with starch, it will change color
into black. But, a presence of clear halos in the medium
indicates a presence of alpha-amylase because it will break down starch.</span>
The answer is B. The air molecules of warm air have high energy and therefore collide with high energy. This causes them to move away from each other with increased temperatures. This is another reason why heating air in a closed container results to high pressure with increased heating.

C. Postoperative suture removal
Explanation:
Antibiotics are medications used specifically for the elimination of bacteria without damaging our body cells. There are several different types of antibiotics to have an effect on all kinds of harmful bacteria in our body. They are medicines that work exclusively on bacteria and are not able to eliminate viruses and fungi.
Medical procedures involving the opening of wounds, such as dental procedures related to dental extraction, tooth replantations or any other procedure involving the opening of wounds or possible bleeding, make the client susceptible to bacterial endocarditis and for this reason it is necessary that the client undergoes antibiotic prophylaxis. However, this prophylaxis is not necessary in procedures such as postoperative suture removal, as it does not involve opening wounds that may cause an infection.
