What is a membrane bilayer?
<span>The most affected organelles are the mitochondria. Since the movement is energy mitochondria provide the energy needed for the muscle tissue contraction using up ATP in the process.

Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. ... Scientists date igneous rock using elements that are slow to decay, such as uranium and potassium.
