The answer is B. the number of cycles per second perceived by the human ear
I got this question right :)
The pitch is the number of cycles per second perceived by the human ear. The correct option is B.
What is pitch?The ability to assess sounds as "higher" and "lower" in the sense associated with musical melodies is known as pitch.
Pitch is a perceptual feature of sounds that allows their ordering on a frequency-related scale.
Pitch in physics refers to a sound wave's specific frequency, which is expressed in Hertz (Hz).
There are two ways in which these frequencies match musical notes. high tone: A high pitch is one that vibrates at a high frequency.
Pitch is a perceptual quantity that depends on the listener, but frequency is a physical quantity that indicates the number of vibrations per second. In truth, our ears perceive pitch rather than frequency.
The pitch is how many cycles per second the human ear can detect.
Thus, the correct option is B.

Which factor can decrease the rate of a chemical reaction?
Olow activation energy
O high pressure
O low temperature
O high concentration of enzyme
Answer:
Low temperature
Explanation:
because.
Have a great day!!!
The factor that can decrease the rate of a chemical reaction is a low temperature.
What is chemical reaction?A chemical reaction is the chemical transformation of one set of chemical substances into another.
A low temperature is one factor that can slow down a chemical reaction. A chemical reaction is defined as a process that transforms one set of chemical substances into another.
The rate of a chemical reaction is a measure of how quickly the reaction takes place.
A low temperature can slow down a chemical reaction by lowering the kinetic energy of the reacting molecules.
This means the molecules move slower and are less likely to collide with enough energy to break bonds and form new ones. As a result, the reaction rate slows down.
Thus, the answer is low temperature.

How does cellular respiration happen?
Answer in a minumum of 5 complete sentences
Answer:
Definition : "Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products."
Simplified : Cellular respiration is used to take in food, then is used to create ATP. ATP is a chemical the cell uses for energy. This process is called aerobic respiration. The process uses oxygen, and has four stages known as Link reaction, glycolysis, the Krebs cycle, and the electron transport chain.

A magazine published an article stating that drinking water obtained from waste water is harmful for health. Why is this information most likely to be incorrect? The article does not provide a scientific basis for the information magazines do not generally publish reliable scientific information drinking water has been obtained from recycled waste water since many years scientific tests show that drinking water obtained from waste water is pure and safe
Answer:
The correct answer is - the article does not provide a scientific basis for the information
Explanation:
Generally, Magazines publish articles with reliable information and sources that are universally accepted or have a scientific basis behind the information. It is already known that wastewater is recycled and purified before making it available for drinking.
In this article, there is no scientific basis behind the information as no scientific data mentioned or ignore test and practice in use from the years which is scientifically tested.

Messenger RNA (mRNA) travels from the nucleus of a eukaryotic cell to the ribosome. At the ribosome, the amino acids are lined up in order as the tRNA molecules line up with complementary bases on the mRNA. This process is called _____ and results in the formation of _____.
Answer:
The correct answer is - translation, polypeptide/amino acid chain.
Explanation:
The translation is the process that involves the movement of mRNA from the nucleus to the ribosome and where amino acids are formed in sequence linked with one another in the same order as the transfer RNA line up with the complementary bases encoded on the messenger RNA or mRNA.
This amino acid chain or the polypeptide folds in a specific way to active protein for the specific function or expression. This process is the last stage or phase of protein synthesis.

what will happen to the concentrations of ATP,NADPH, and sugar when you add paraquat
Answer:
Increase ATP
Decrease NADPH
Decrease Sugar
Concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.
The concentrations of ATP,NADPH, and sugar decreases when you add paraquat because paraquat is a toxic chemical which blocks the activity of respiration in plants leading death of those plants. Paraquat inhibits the ATPase activity which is responsible for the production of ATP.
So due to no cellular respiration no ATP is produced. Paraquat (PQ) also inhibit photosynthesis so no glucose as well as NADPH is produced so we can conclude that concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.
