This is a current in a fluid that results from convection. Convection currents occur in the magma (heated) parts of earth. Convection currents can carry heat from earths mantle to the surface.
Answer:
Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together.
There are two classes of membrane transport proteins—carriers<span> and </span>channels<span>. Both form continuous </span>protein<span> pathways across the lipid bilayer. Whereas transport by </span>carriers<span> can be either active or passive, solute flow through </span>channel proteins<span> is always passive.</span>
C, the distribution process. allows the body to have equal amounts of energy
The second statement is correct.
