Im so confused i would help you i just need a better understanding.<span />
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>

Biogeochemical cycles
<h3><u>Explanation</u>;</h3>
- <em><u>Biogeochemical cycles are cycles through which earth's elements undergo chemical reactions that build molecules, destroy molecules, and change molecules into other molecules, reusing the same atoms over and over.</u></em> These cycles includes a variety of chemical, geological and biological processes.
- The major biogeochemical cycles include; water cycle, carbon cycle, nitrogen cycle and oxygen cycle. These cycles function to conserve and recycle matter which is part of living organisms.
Answer:
not enough skin exposure to the sun to make Vitamin D.
Explanation:
The correct answer would be <u>not enough skin exposure to the sun to make Vitamin D.</u>
The body makes vitamin D by being exposed to the sun and this vitamin and its metabolite are quite important in the homeostasis of calcium. Calcium on its own is very essential to the formation of bones in the body.
<em>Hence, when the skin is not adequately exposed to the sun, the body becomes short of vitamin D and this disrupts the homeostasis of calcium and the formation of bones in the body. Thus, osteoporosis, also known as weak bones, may result. </em>
