Dumping raw sewage into a river will reduce the amount of dissolved oxygen in the water. What effect could dumping raw sewage most likely have on a river ecosystem?
O an increase in cellular respiration due to the rising level of phosphates in the water
O a decrease in water temperature due to the energy transfer from osmosis
O a decrease in aquatic animal populations
O an increase in fish populations

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center. because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane. the diverse proteins found in and attached to membranes perform many important functions. the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together. membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
