The doppler effect is when sound travels away from a moving object, the frequency can be different depending on the location at which you recieve the sound.

I hope that helps

Answer:

Doppler effect occurs when there is relative motion between the source and the observer, there is apparent change in frequency or wavelength of the wave. When, the source and observer come closer, the apparent frequency increases and wavelength decreases that is the spectrum is blue shifted. When the two move far apart, the spectrum is red-shifted which means the frequency decreases and wavelength increases.

We obtain the spectrum of bodies in the universe. If the spectrum is red shifted, it indicates that the body is moving away from us while a blue-shifted spectrum indicates that the body is moving towards us.

1. Why is Earth an example of a system?
AURORKA [14]

Answer:

The earth can be said to be a system because each component inside it interacts so that it creates a very large number of collectivities.

Explain the relationship between the processes of breathing and cellular respiration
Eduardwww [97]

Cellular respiration uses oxygen to release the energy stored in food.

Explanation:

In breathing living organisms take oxygen and release the carbon dioxide it is similar to the aerobic respiration.

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide!

Most cells fall within the range of 5-20 microns. What factors keep the size of the cell within these boundaries?
Tema [17]

Answer: Cytoplasm and organelles

Explanation:

Normally, a cell cannot attain a size greater than 20 microns due to the limits imposed by the size inter-relationships of its components. For example, there is a relationship between the amount of nuclear material and the size of a cell; this limits cells to a size where there is an optimal proportion of nuclear material to the rest of the cell.
