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.

anaerobic respiration.
Due to anaerobic respiration, one by- product of this process is lactic acid which builds up in the muscles and causes the fatigue.
Thats the short answer, I don't know if you want more details such as using the equations of both types of respiration, etc.

Answer:
Option B, Get the results approved by government agencies
Explanation:
The findings of the student can be verified by someone who has already conducted research or studies in the same field earlier. Since a government agency would have carried out a sincere study and their findings would be more accurate as compared to any of the secondary sources, newspaper or magazine publication, it would be advisable to get the results verified by some government agency.
Also a finding attested by a government organization is more trusted than its verification from any other sources.
Hence option B is the correct choice of answer
