Using the Doppler shift effect
If the celestial body is in the blue shift, then its moving towards earth and if it's in the red-shift then it's moving away from earth.
Explanation:
Doppler shift effect is a phenomenon that occurs in waves due to relativity. When an object is relatively moving toward an observer, it tends to ‘compress’ the waves into a higher frequency/ shorter wavelength. Visible light will be observed in blue shift because blue light is of higher frequency than red. If the object is relatively moving away from the observer, it tends to ‘stretch’ the waves. Remember ALWAYS this is relative to the observer. hence giving them the perception of viewing the object in longer wavelength. The object is observed in red shift because red light it has a longer wavelength/lower frequency than blue light.
This phenomenon is not limited to light waves, but happens even in mechanical waves like sound. When a wailing ambulance is approaching you, you hear it in high pitch. However, when it passes you and moves away from you, you hear it in low pitch.

Answer:
Hello your answer is C
Explanation:
i hope this helps ♥︎♡︎♥︎♡︎
Answer:
a cell in a plant that is composed of a cell wall and multiple organelles, like a huge vacuole and chloroplasts that carry out photosyntheses. They are the building blocks for plants.
Explanation:
Answer:
b the turgor pressure will increase but the cell wall prevents the cell from exploding
Explanation:
The plant cells are exposed in a change of pressure liquid depending the quantity of solids that are inside and outside the cell. Like in this case, the hypotonic solution is the one that has less solids outside the cell, that is the reason why the water enters the cell to equilibrate the concentration of solids inside and outside the cell.
