A life cycle is the series of stages something passes through during its lifetime. We also use the term for things that are not living, like cell phones. The life cycle for anything you buy includes ...

With only half the DNA, when the parent cell combines with another parent cell, the proper amount of DNA is maintained. This solution is called meiosis. Mitosis describes the process by which the ...

This cycle proceeds continuously as long as the car is powered up and in motion; when it's idling, output from the fuel cell is shut off to conserve fuel, and the ultracapacitor takes over to ...

Then, in mice engineered with a fluorescent reporter protein, they pinpointed the precise moment in the cell cycle in which B cells mutate. What they found was striking -- during inertial cycling ...

28 If the ovum does not join with a sperm cell in the oviduct, the lining of the uterus begins to break down again and the cycle repeats. Figure caption, The thickness of the uterus lining varies ...
