In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...

Non-exercise activity thermogenesis (NEAT), also known as non-exercise physical activity (NEPA), [1] is energy expenditure during activities that are not part of a structured exercise program.
Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.

The process of adaptation contributes to this "success" by impacting rates of survival and reproduction, [2] which in turn establishes an organism's level of Darwinian fitness. [5] In life history theory, evolution works on the life stages of particular species (e.g., length of juvenile period) but is also discussed for a single organism's ...
