What characteristics of a sound wave determine the loudness and pitch that we perceive?

The intensity of the sound wave, that is the amplitude and distance from wave source, determines the loudness of a sound. The frequency of the sound wave determines the pitch that we perceive.

Hope this helped

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

yes

no

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
