Answer:
Proteins.
Explanation:
Proteins (also called polypeptides) are large biological molecules which consists of one or more chains of amino acid. Proteins perform a series of functions which are catalysing metabolic reactions, DNA replication, providing structure to cells, transport molecules from one location to another within an organism etc.
Collagen consists of amino acids bound together to form a triple helix of elongated fibrils. It can be found in the skin, ligaments etc.
Enzymes are globular protein molecules which have the tertiary structure. They are generally rounded, "squashed" ball shape. Others include fibrous proteins which are long thin structures and are found in muscles and hair.
The correct answer is D. Elements are created that differ from the reactants.. Because in a eeaction, the product is different than the reactants. Take NaCl for example.

The percent error in the initial measurement would be 6.47%
<h3>Percent Error</h3>
Percent error in any measurement is mathematically given as:
absolute error/true measurement x 100%
In this case;
True measurement = 1.34 qt
Absolute Error = 1.34 - 1.25
= 0.09 qt
Percent error = 0.09/1.34 x 100%
= 6.47%

Answer: There are 
of 
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
Thus there are of
