February 13, 2017. Community. December 29, 2016. The definitive source of meaningful and informative explanations of biological At the cellular level, organelles interact with each other as part of a coordinated system that keeps the cell alive, growing and reproducing. Interactions and coordination between organs and organ system determines essential biological activities for the organism as a whole. Internal and external factors can activate responses in the organisms.

Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology -based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionism) to biological research. A biological system is a complex network of biologically relevant entities. Biological organization spans several scales and are determined based different structures depending on what the system is. Examples of biological systems at the macro scale are populations of organisms. In biology, a biological system (or organ system or body system) is a group of organs that work together to perform a certain task.

in this video I'm going to talk about the biological basis of schizophrenia schizo free Nia which is a common long-term mental disorder that causes a large amount of distress and disability schizophrenia is the prototype of the category of mental illness called the psychotic disorders let me just write that psychosis psychosis and psychosis refers to some specific abnormalities of cognition and often characteristically abnormal perceptions of reality these may include hallucinations which The fundamental justification for yield improvements in aeroponic systems, versus hydroponic alternatives, is the superior access that roots have to oxygen.At any one time, the optimal amount of irrigation can be derived from balancing the plant’s requirement for sufficient nutrients (of a given type), water, and gaseous exchange to meet biochemical requirements within the plant root cells. 2015-02-01 · Systems biology has provided an important motivation and material for extending philosophical conceptions of mechanistic explanation to dynamic systems (see Bechtel, 2011, Bechtel and Abrahamsen, 2005, Bechtel and Abrahamsen, 2010, Brigandt, 2013, Fagan, 2012, Levy and Bechtel, 2013).
