Document Summary
Squid giant axon control water jet propulsion system. Homeostasis: tendency of the body to maintain equilibrium within the body"s environment even when there are external fluctuations. Conformers: internal environment is dependent to the external environment and will change with it straight line on a graph. Regulators: internal environment is independent to the external environment. Positive feedback: when the stimulus increases e. g. oxytocin. Acclimation: adaptation to a new variable in a lab environment. Acclimatization: adaptation to a new variable in a natural environment. Adaptation: the process of change through natural environment that will give a new characteristic that is fitter to the new environment. Fluid mosaic - lipid bilayer containing integral and peripheral proteins that separates extracellular to intracellular fluid. Permeability depends upon wax, keratin and lipids. Lipid raft: more rigid area due to accumulation of cholesterol and glycolipids. Phospholipids are amphipathic both hydrophilic and hydrophobic parts. The more disorder there is the more fluid it is.
