C. Ice is less dense than water which means water condenses when it freezes allowing the ice in a lake to float on top of the water preventing the water below from freezing.
When an object from a pause state begins to move the potential energy is changed into kinetic energy. One of the example is the yo-yo, it has stored energy due to its position. Once the yo-yo begins its fall the potential energy will change to kinetic energy and vice versa.
1. Rhythm generators (SA node)
2. Conductive cells (node cells)
3. Contractile cells (myocardial cells)
It is moved out of the ER, tagged with ubiquitin in the cytosol and then degraded by the proteasome in the cytosol.
