Geothermal energy is an alternative energy source, although it is not resourceful enough to replace more than a minor amount of the earth’s energy needs. why is this? a. the center of the earth is not hot enough to make a significant energy contribution. b. once the cool water is poured down the well and filters through the rocks, the rocks cool off and are no longer hot enough to turn water into steam. c. drilling through the earth to reach areas hot enough to create steam is possible, but very expensive and difficult. d. there are only a few places where the earth’s core is hot. it is cool in places like antarctica.

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.
