Why do soft sounds do less damage to your ears than loud sounds

Answers

Well loud sounds tend to hurt the ear drum and can cause hearing issues because of how strong the vibration is and soft sounds don’t have a strong vibration which means it doesn’t have any effect on the ear drum

Answer:

"The damage done by noise depends mainly on how loud it is and on the length of exposure. The frequency or pitch can also have some effect, since high-pitched sounds are more damaging than low-pitched sounds. Noise may tire out the inner ear, causing temporary hearing loss."

what is the difference between light dependent and light indepenedent reactions

Answers

Answer:

The difference between light dependent and light independent reactions is light independent is energy from sunlight that is absorbed by Chlorophyll. Also light dependent is energy that is converted into stored chemical energy. In the independent reactions, the chemical energy basically harvests during the light dependent reactions, which drives the assembly of these sugar molecules from carbon dioxide.

The light dependent reaction helps to make ATP and NADPH, the “batteries”. Those are then given to the stroma for the light independent reaction, which makes the sugar, of photosynthesis. Good luck!

How is the rate of photosynthesis affected by wavelength?

Answers

Photosynthesis is after by wavelengths of light because the thylakoids (light dependent reaction) absorbs red and blue light the best, and reflects green and yellow light. So leaves aren’t actually green and yellow, but we see that because we see those reflected wavelengths of light. Cool, right?
