The correct answer is frequency.
The pitch can be defined as the quality of sound produced by the rate of vibration producing it.
It is directly related to the the frequency of the sound wave. If the frequency is increased then its pitch will also increase and vice versa.
As for normal people it is a bit difficult to differentiate between the two but the musician are trained so they can differentiate the difference between the two even if the difference is 2 Hz
Option c a slow mutation rate
A, turning on gene expression
Answer:
Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.
I’m not exactly sure what your experiment is, but I can make a few guesses. Maybe a substance is being mixed with the baking soda and breaking it up can help with dissolving. Or maybe the baking soda must fit through a small opening and cannot be lumpy. Please message me or comment under my response with further detail if u still need help.
