The answer is a. to determine what sort of data table will be most useful.
Controlled experiment is used parallel with experiment in which some alteration of the subject is induced. This is because this way can be compared in treated and non-treated subject. When sort of data table is necessary, using the controlled experiment, it can be determined what sort of data table will be most <span>useful.</span>
Answer:
The correct answer will be- the color change will be observed and the solution will turn purplish-black.
Explanation:
Iodine test is performed to test the presence of the carbohydrates mainly starch.
The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.
In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.
I need to have some choices
Answer:
True.
Explanation:
Large proteins are regarded as large size molecules , or macro-molecules. And they are known to made up or contain polymers of structural units, which are known as amino acids.
In summary, large proteins are generally known to consist of several distinct protein domains, i.e structural units that fold more or less independently of each other.
Therefore , in this case, the large protein will remain in the capillary, and eventually result to the development of an osmotic pressure difference across capillary walls.
is there a question selection?
