When you do a load of laundry, why do you not just drop a bar of soap into the washing machine? In other words, why is laundry detergent sold as a liquid or powder?
Biology 2 Notes CONCEPT 29.5: CELL MEMBRANES -Separate of fluid compartments is by cell membranes at small scale. -Each cell has intracellular fluid inside separated from the extracellular fluid bathing the cell on the outside. The cell membrane separates the two. -Pump ions between the intracellular fluid and extracellular fluid -Play key roles in producing and receiving physiological signals. Animals exhibit a high degree of division of labor Tissue is an assemblage of cells of similar type. Organ consists of two or more types of tissue with a defined structural relationship to each other. Multiorgan system consists of multiple organs working together. Organ Tissue (nervous/muscle) Cell - rapid transport system required for division of labor to be successful. Most types of animals have a circulatory system that serves this role. In many cases, O 2ransport is the most pressing of all transport needs. For this reason, the circulatory system correlated with metabolic rate. Animals with high metabolic rates require high rates of O 2ransport and have evolved circulatory systems with exceptional abilities for rapid 2 transport. - each cell must make its own ATP (immediate energy source for most cellular functions) but it is not transported from cell to cell. Each cell must make its own ATP, and the rate of ATP supply in each cell depends on that particular cell’s ability to synthesize ATP. - Energy is transported from organ to organ and from cell to cell in the form of
