One way in which experimental research differs from observational research is that only experimental research can show cause and effect and is denoted as option D.
<h3>What is Cause and effect?</h3>
This is the situation in which one event contributed to the formation of another according to the type of relationship between the variables.
This is commonly used in experimental research so as to prove the interconnection and is tested by scientists in other to ascertain its authenticity.

C. A cooking center often includes things for measuring and counting
The correct answer is; "Assembling molecules in either hydroxyl or carboxyl functional groups"
Polymers are formed from monomers either by condensation or by addition of monomers.
A polymer is formed by the joining of one or more monomers. This can happen in either of the following ways;
Condensation polymerization involves the loss of a small molecule. When the molecule that is lost is water, we can call it dehydration. Loss of molecules does not occur in addition polymerization.
The two monomer molecules that join to yield the polymer by dehydration must have H and OH moieties in suitable positions for dehydration to occur. A typical example is assembling molecules in either hydroxyl or carboxyl functional groups.

I am assuming you mean the nutrient groups of macronutrients and micronutrients.
Macronutrients:
<em>fats</em>
<em>carbohydrates</em>
Micronutrients:
<em>calcium </em>
<em>zinc</em>
<em>vitamins</em>
Hope this helped :)
