We hear sound because of sound waves.

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

Answer:

Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones or ossicles into the inner ear. The inner ear is shaped like a snail and is also called the cochlea.

Explanation:

<h3>Here are 6 basic steps to how we hear:</h3>

1.Sound transfers into the ear canal and causes the eardrum to move

2.The eardrum will vibrate with vibrates with the different sounds

3.These sound vibrations make their way through the ossicles to the cochlea

4.Sound vibrations make the fluid in the cochlea travel like ocean waves. Movement of fluid in turn makes the hair cells

5.The auditory nerve picks up any neural signals created by the hair cells. Hair cells at one end of the cochlea transfer low pitch sound information and hair cells at the opposite end transfer high pitch sound information.

6.The auditory nerve moves signals to the brain where they are then translated into recognizable and meaningful sounds. It is the brain that “hears”.

A system of gene control in bacterial operons in which glucose is used preferentially and the metabolism of other sugars is repr
Levart [38]

Answer:

Catabolite repression

Explanation:

Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.

It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:

  • sensory systems-detects ratios of glycolytic intermediates,
  • global regulators-control the expression of genes that encode for enzymes.

Explain how is it possible that when you look at the nice guy he may be looking at stars for millions of years ago
USPshnik [31]

Answer:

The reason is because it takes a long time for the light from the stars in the sky to reach earth, so the light the star was producing millions of years ago has just now reached Earth.

Hope this helped! :)

the graph shows how the rate of photosynthesis of a plant varies with light intensity. interpret the graph and justify statement
dezoksy [38]

The graph shows that the rate of photosynthesis increases with increased light intensity, other conditions being constant.

<h3>Photosynthesis and light intensity</h3>

From the graph, the rate of photosynthesis increases with an increase in light intensity.

At low light intensity, the photosynthesis rate increases with an increase in the concentration of carbon dioxide and level off at some point.

With medium light intensity, the rate of photosynthesis is about twice that of low light intensity under the same concentration of carbon dioxide. It also gradually levels off when the concentration of carbon dioxide reached a particular point.

The same trend applies to high light intensity. The rate of photosynthesis increased accordingly, much more than low and medium-intensity light.

Both light and carbon dioxide concentration can limit the rate of photosynthesis. When both factors are abundant, photosynthesis can be limited by other factors such as water, nutrient, etc.
