Skipping is a rhythmic form of bipedal locomotion that combines the step and hop. [1] Skipping can be performed bilaterally (alternating lead foot) or unilaterally (continual lead foot). [ 2 ] Unlike walking or running , skipping is an asymmetrical movement in which successive footfalls are not evenly spaced in time. [ 3 ]
Open top bus – Bus, usually a double-decker bus, without a roof . City Sightseeing operates a service by this name in many cities; Tour bus service – Sightseeing bus service for tourists
Many tours also have a live guide. Tourists may board and leave the buses within their ticket's time limit at the different bus stops on the circular routes. This is called hop-on-hop-off. Many cities have more than one route to showcase all the different sights and attractions. On some routes, buses leave the city for suburban sights.
Despite the great potential complexity and diversity of biological networks, all first-order network behavior generalizes to one of four possible input-output motifs: hyperbolic or Michaelis–Menten, ultra-sensitive, bistable, and bistable irreversible (a bistability where negative and therefore biologically impossible input is needed to return from a state of high output).
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 ...
This is an annotated list of biological websites, including only notable websites dealing with biology generally and those with a more specific focus. Ask A Biologist - has been hosted by ASU School of Life Sciences since 1997.
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted to future generations.
In network theory, link prediction is the problem of predicting the existence of a link between two entities in a network. Examples of link prediction include predicting friendship links among users in a social network, predicting co-authorship links in a citation network, and predicting interactions between genes and proteins in a biological network.
