6 0

<span>Muscle cells are uniquely adapted to contractile function due to three main things. FIrst, they have a large capacity for storage of readily available glycogen to use for work. Second, they contain the actin and myosin cross-bridge cycling structure to perform a contraction of a muscle fiber. Finally, each fiber has central nervous innervation to control contraction and relaxation of the muscle fibers.</span>

Earth’s energy sources include both renewable and nonrenewable resources. Name at least three sources of energy that could be us

seropon [69]

Geothermal energy for heating. Solar power, or HydroElectric energy. The most efficient/Ideal one would HydroElectric energy. The reason why I say this is because HydroElectric energy does not pollute the environment, or produce harmful fumes. It also produces a lot of energy to power multiple homes.
