<span>useful substances must be selectively reabsorbed
Filtration of blood by kidney only selected based on the molecule size. That means all small molecule will enter the kidney, doesn't matter whether it is toxic or useful.
But kidney has another mechanism such as reabsorption. In </span>reabsorption, some specific useful molecule(like glucose) will be absorbed back.
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 word is scapegoat in the blank is scapegoat.
The two types of of pure substances are elements and compounds.
Since prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.
<h3>What are prokaryotic cells?</h3>
Prokaryotic cells are cells that are characterized by the absence of a nucleus or any other membrane-bound organelles.
On the other hand, eukaryotic cells have the presence of a membrane-bound nucleus that stores their genetic material.
Another important feature of prokaryotic cells is that they are haploid in nature i.e. they do not have chromosomes that occur in homologous pairs and have just one chromosome.
Therefore, it can be said that because prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.
