Two sound waves are moving through a medium at the same speed. If wave x has a greater frequency than wave y, then wave x
Answers
Correct Question:
Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X
A. has a lower amplitude.
B. has a shorter wavelength.
C. has a longer wavelength.
D. has a greater amplitude.
Answer:
C. has a longer wavelength.
The basic equation of frequency and speed are
velocity = frequency x wavelength
When both waves' velocities are the same then
v1 = v2
f-1 x wavelenght-1 = f-2 x wavelenght-2
Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.

What is coal used for
Answers
Answer: Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
Explanation:
Infer why base substitutions in the third position are least likely to cause a change in the amino acid for which it coded.
Answers
Answer:
Because of the codon oscillation.
Explanation:
The formation of codons is susceptible to the occurrence of oscillation, which is the term that corresponds to the fact that many codons have synonyms in the third position, that is, in the third letter. For example, the codon CUA, which represents leucine, will also represent leucine if it is presented in CUU, CUC and CUG forms, due to the oscillation in the third position. This allows the tRNA to recognize any of these codons and pair with the anticodon smoothly and without errors.
DNA is in what form during interphase?
Answers
Answer:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
DNA is in form during interphase During interphase, the cell DNA isn't condensed and is loosely distributed.
What happens during interphase?A stain for heterochromatin (which shows the placement of chromosomes) indicates this large distribution of chromatin. The equal stain additionally indicates the organized, aligned shape of the chromosomes in the course of mitosis.
Nuclear DNA remains in a semi-condensed chromatin structure throughout the interphase. During the S phase, DNA replication results in the creation of identical pairs of DNA molecules, known as sister chromatids, which are tightly linked to the centromeric region.
During the S phase, the centrosome is duplicated.

Answer:
The second option
Explanation:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.

Answer:
An interesting episode of the aquarium I had was seeing a dolphin show. The dolphin was super smart, and I have to admit it was smarter than me. I mean I was like 3 when I went there so, I guess that is normal? Anyways, the dolphin was doing cool tricks like twist jumping, and even I tried it but failed. The dolphin went to the worker when the worker called its name. I learned that day that you shouldn't underestimate dolphins because they are smart.

Describe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil
Answers
Answer:
The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.
Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.

A cup is surrounded by air in room temperature
Describe the energy transfer between the water and air if the system is at equilibrium
A.Energy is transfers from air to the water
B. Energy transfers from water to the air
C. Energy transfers back and forth between air and water
D.None of the above
Answers
The energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy. So, the correct option is D.
What do you mean by Equilibrium state?Equilibrium may be defined as a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.
When the system is at equilibrium, the energy transfer between water and air surrounding the cup does not take place. It will only take place when there is a difference between the concentration of two solutions or objects.
Therefore, the energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy.
