membrane transport refers to the mechanisms by which solutes cross the pasma membrane, but there are additional prockaryotype cell structures through which a solute would pass when entering or exiting a cell,. Sequence the path of a solute from.....

Which of the following molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism? Select all that apply.

Some solutes are able to pass directly through the lipid bilayer of a plasma membrane, whereas other solutes require a transport protein or other mechanism to cross between the inside and the outside of a cell. The fact that the plasma membrane is permeable to some solutes but not others is what is referred to as selective permeability. Which of the following molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism? Select...

The cross-section of a nuclear power plant's cooling tower is in the shape of a hyperbola. Suppose the tower has a base diameter of 156 meters and the diameter at its narrowest point, 48 meters above the ground, is 52 meters. If the diameter at the top of the tower is 104 meters, how tall is the tower? The tower is about ___ meters tall.
