Except for the last few minutes, which are highly automated and rigid, scheduled activities rarely take exactly the scheduled time, and the T-minus clock only corresponds approximately to the time until launch. A hold is the suspension of the normal countdown process, during which the T-minus clock is stopped and no planned activities take ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
As a tubulin dimer consists of one α-tubulin and one β-tubulin, one end of the neurotubule is exposed with the α-tubulin and the other end with β-tubulin, these two ends contribute to the polarity of the neurotubule – the plus (+) end and the minus (-) end. The β-tubulin subunit is exposed on the plus (+) end.

t = time. The model can also be written in the form of a differential equation: = with initial condition: P(0)= P 0. This model is often referred to as the exponential law. [5] It is widely regarded in the field of population ecology as the first principle of population dynamics, [6] with Malthus as the founder.
M phase See mitosis. macromolecule Any very large molecule composed of dozens, hundreds, or thousands of covalently bonded atoms, especially one with biological significance. . Many important biomolecules, such as nucleic acids and proteins, are polymers consisting of a repeated series of smaller monomers; others such as lipids and carbohydrates may not be polymeric but are nevertheless large ...
Evolutionary game theory (EGT) is the application of game theory to evolving populations in biology.It defines a framework of contests, strategies, and analytics into which Darwinian competition can be modelled.
