Answer:
B). Law
Explanation:
A law is defined as the statement of an observed order, sequence, or relationship of a natural phenomenon which is invariable or always true under certain specific conditions while the theory is characterized as the explanation of this observed phenomenon and prediction of the new facts or phenomenon which was previously not observed to set out the new laws or principles of something. Thus, the theory is the base for the formation of law and hence, <u>option B</u> is the correct answer.
Answer : The mass of needed are, 44.5 grams.
Explanation :
First we have to calculate the moles of Na.
Now we have to calculate the moles of NaCl.
The balanced chemical reaction is:
From the reaction, we conclude that
As, 2 mole of produces from 2 mole of
So, 0.761 mole of produces from 0.761 mole of
Now we have to calculate the mass of
Molar mass of = 58.5 g/mole
Therefore, the mass of needed are, 44.5 grams.
Answer:
The correct option is: c. petroleum jelly, d. Polyethylene glycol 4000/600 mixture
Explanation:
Topical medications are used for the treatment of ailments and include ointments, gels, lotions creams etc. that can applied directly on the surface of the body i.e. skin.
An ointment base medication gets rapidly absorbed into the skin. Some of the examples of <u>ointment bases</u> include water-soluble bases: <u>polyethylene glycol</u>, hydrocarbon bases: <u>petroleum jelly</u>, paraffin wax.
As known, nitrogen could form 3 bonds based on octet rule, because it has 5 valence electrons. That means it needs 3
36% amount of radiolabeled proline can be expected in the translated polypeptides if a cell-free translation experiment like Nirenberg and Matthaei is performed.

What do you mean by Radiolabeling? </h3>
Any combination of radioactive material and a chemical. A common technique in pharmaceutical research and development for tracking specific molecules and compounds is radiolabeling. It resembles carbon dating, a more well-known method for determining the age of organic substances based on how quickly carbon decomposes. Additionally, radiolabeling is a method used to follow a radioisotope-containing molecule as it moves through a biological system, metabolic pathway, cell, tissue, or organism. Specific atoms are "tagged" by substituting their isotopes in the reactant.
