What happens to air when it is heated by the sun?

whats the chocies

Explanation:

when air is heated it rises. ... On a small scale, this effect can be seen when the Sun heats up a field and the air above it rises in a therma

The large amount of energy that comes from the sun heats up the Earth's surface and the air around it. As the air is heated up to a certian tempurature, it exapnds and density becomes a smaller amount. The warm and hot air begins to rise into the atmosphere and then the dense, cold air flows and/or sinks down to then replace the warmer air that is still rising.

Hope this helps you out! ☺

answertheory;

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
