The scientific question that can be answered through investigation will be:

<em>"Which of the four types of macromolecules, and in which proportions, are present in the food sample?"</em>

<h3>What is scientific question ?</h3>

A scientific question is a question that may lead to a hypothesis and help us in. answering (or figuring out) the reason for some observation.

A scientific question simply means a question where a researcher designs a question in order to get an answer to a particular investigation.

According to this question,

Since the researcher wants to know the person responsible for the classroom good mess by determining which macromolecules are present in the mystery food sample, then the question will be<em> "Which of the four types of macromolecules, and in which proportions, are present in the food sample?"</em>

Answer:

Bacteria are vital in keeping nitrogen cycling through the ecosystem, and nitrogen is vital to plant growth. Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn't return their nutrients back to the system

Carboxypeptidases can be used to determine the entire sequence of short peptides (&lt;50 amino acid residues) and it starts by r
zepelin [54]

Answer:

A. True

Explanation:

Carboxypeptidases are enzymes which function in the digestion of short peptides known as oligopeptides in the small intestine. Oligopeptides contain between 10 to 50 amino acid residues.

The two carboxypeptidases A and B involved in the digestion of proteins in the small intestine are secreted by the exocrine glands of the pancreas.They are both zinc-containing enzymes which remove successive carboxyl-terminal  (C-terminal) residues from oligopeptides until free amino acids are obtained.

Since they function in this way, they can be used to determine the entire sequence of short peptides or oligopeptides.

What is true regarding the calculation in redox titration? group of answer choices moles of the oxidant equal mole of the reduct
SVEN [57.7K]

Moles of titrant are lost in the calculation in redox titration.

"The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration.

The equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, is to be detected by the titration. The stoichiometry of the reaction determines how many reactants have been combined at the equivalence point.

Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. In the realm of analytical chemistry, titration is a crucial technique.

If you determine the molar heat of neutralization for an acid is 49.1 kJ/mol and the accepted value is found to be 55.2 kJ/mol,
zhenek [66]

Answer: % Errror = 11.05%

Explanation:

Percentage error is the difference between the measured value and the theoretical value as expressed in percent.

That is;

% Error =

( Theoretical value -measured value) /(Theoretical value) × 100

Theoretical value =55.2kJ

Measured value = 49.1kJ

% Error = (55.2-49.1)/(55.2) ×100

%Error = 6.1/55.2 ×100

% Error = 0.1105 ×100

% Error = 11.05

Therefore the percentage error is 11.05%
