Frequency- number of wave cycles that occur in a given amount of time.
Pitch- number of wavelengths in a given amount of time.
Amplitude- fluctuation or displacement of a wave from its mean value. That means how high or low they are away from the center line.
Volume- The perception of loudness from the intensity of a sound wave. The higher the intensity of a sound, the louder it is perceived in our ears, and the higher volume it has.
Wavelength- the distance between the tops of the "waves".
Answer:
Plants, by contrast, breathe through tiny pores called stomata on the underside of their leaves. These pores allow carbon dioxide to enter and oxygen to exit. Plants open and close their stomata in response to changes in their environment so they can get the CO2 they need, and avoid drying out.
Explanation:
In a river, sediment is deposited on the inside bends.
when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.
<h3>What does molecular clock mean?</h3>
The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.
Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.
Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).

Answer:
A bicameral legislature has legislators in two separate assemblies, chambers, or houses. ... Enactment of primary legislation often requires a concurrent majority—the approval of a majority of members in each of the chambers of the legislature.
