The correct answer is (a) tightening the string.

The sound frequency of musical instruments can be controlled by changing the settings of the strings.  When the string of an instrument  is stretched between two point, the tightened strings produce tension. Here, tension refers to how tightly the string is being stretched. Tightening of the string provides higher frequency. The higher frequency vibrations are carried to ear which considers high frequency as high pitch.

In photosynthesis, carbon dioxide is reduced and h2o is oxidized. What type of chemical reaction is this?.
Vilka [71]

In photosynthesis, carbon dioxide is reduced and H₂O is oxidized. The type of chemical reaction is an oxidation-reduction reaction.

<h3 />

Explanation

Oxidation-reduction reaction are reactions that take place in electrochemical processes. Reduction is the reaction of decreasing oxidation number and increasing electrons and it can be said that reduction is the reaction of a substance losing oxygen. Oxidation is the reaction of increasing the oxidation number and decreasing electrons and can be said that oxidation is a reaction where the reaction of a substance binds oxygen.

Photosynthesis is one type of oxidation-reduction reaction that occurs naturally in everyday life. Photosynthesis has a complex process and involves green plants and certain bacteria. In the event of photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized to oxygen.

The oxidation-reduction reaction in photosynthesis is:

6CO₂(g) + 6H₂O(l) + energy --> C₆H₁₂O₆(aq) + 6O₂(g)

"In proteins, structural segments called ____ provide flexibility that allow parts of the protein to bend, fold, or move."
Rainbow [258]

Answer:

The correct answer is "random coils".

Explanation:

Random coil is a type of polypeptide secondary structure comprised of conformation that do not follow an established conformation but rather are oriented randomly. These random coils conformations provides flexibility to proteins, since the lack of a particular structure (such as alpha helices or beta sheets), allows the protein to bend, fold or move.
