The decay of potassium to argon, uranium to lead, and one isotope of lead to another are some common yardsticks used to date very old rocks. These dating methods allow scientists to put real ages on rocks with astonishing accuracy.

Explanation:

The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.

Cell membranes are made up of a lipid/phospholipid bilayer in which each layer consists of an hydrophilic head (water loving) and a hydrophobic tail (water fearing). The hydrophobic tail of each layer is oriented inward and the hydrophilic heads are oriented outward so the cell can interact with water molecules inside (the cytoplasm) and outside the cell environment. This orientation forms a critical part of the function of the cell membrane that makes it a selectively permeable barrier that regulates what goes in and out of the cell.
