Farah is doing an experiment that involves calculating the speed of a longitudinal wave. What will most likely happen if she increases the temperature in the room?

Answers

Answer 1

Answer: The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.

Answer 2

Answer:

Explanation:

In the given problem, Farah is doing an experiment that involves calculating the speed of a longitudinal wave

For example, Sound wave is a longitudinal wave. It travels faster in solid than liquid and gas as the solid is more denser.

The speed of the sound increases with the temperature. At higher temperature, the molecules have more kinetic energy. They can vibrate faster. The sound wave can travel faster. The speed of the sound in the room temperature is 346 m/s.

If Farah increases the temperature then the sound wave travels faster.

Glaucoma is a leading cause of blindness. Studies have linked a common form of glaucoma to three genes and more than 20 genetic loci. Which best describes glaucoma?a. . a recessive trait that requires multiple recessive alleles to be expressed
b. . a polygenic trait that is influenced by the number of alleles present
c. . a codominant trait that is expressed more often when more dominant alleles are present
d. . a dominant trait that depends on the presence of only one of many dominant alleles

Answers

The answer to the question given is letter b. a polygenic trait that is influenced by the number of alleles present.

Large multiplex families suitable for linkage analysis are typically affected by early-onset forms of glaucoma inherited as Mendelian dominant or recessive traits.
>A polygenic trait is one whose phenotype is influenced by more than one gene.
>A polygenic inheritance is one genetic mechanism giving us a continuous range of possibilities.

The answer is b. a polygenic trait that is influenced by the number of alleles present.

There are three genes linked to a common form of glaucoma, so it must be the polygenic (meaning more than one gene included) trait. The polygenic traits are influenced by the number of alleles. In this case, there are more than 20 genetic loci which means there must be a great number of alleles for all loci.

Coral reefs are unaffected by pollution. Please select the best answer from the choices provideda. True
b. False

Answers

b. False

Coral reefs are dying In particular coral mining, agricultural and urban runoff, pollution, overfishing, etc.

The given statement is False.

Corals reefs are affected by the pollution. When sediments and the other pollutants enter the water, they smoother the coral reefs and they damage the coral reef and increases the growth of the damaging algae.

Pollution make the corals more susceptible to disease and can also alter their rate of reproduction.

Which structure branches further into alveoli?a. nasal cavity
b. epiglottis
c. bronchiole
d. laryngopharynx

Answers

Answer:

The correct answer is option c. "bronchiole".

Explanation:

The passage of airway within the lungs is known as bronchus. However, air exchange does not happen in the bronchus, it happens in small air sacs named alveoli. The smaller versions of the bronchus are known as the bronchiole, which branches further until it becomes the alveoli, the structure at which air exchange takes place.

c. Bronchiole

They will branch all the way to terminal bronchiole before they go into alveoli
