nucleic acids
proteins
When there are roughly equal numbers of molecules moving in either direction across a semipermeable membrane, and there is no further change in concentration on either side of the membrane, this has been reached.
(a)
Which of the following types of cellular transport is demonstrated by the illustration above?
Active Transport
Facilitated Diffusion
Endocytosis
Diffusion
Water bonds are considered polar bonds because of what characteristics of water molecules?
the hydrogen and oxygen atoms are ions, meaning they have complete positive and negative charges.
the oxygen atom is slightly positive, and the hydrogen atoms are slightly negative.
shared electrons spend more time around the hydrogen atoms than the oxygen atoms.
the oxygen atom is slightly negative, and the hydrogen atoms are slightly positive.
Which means of particle transport is shown in Figure 7–5 above?
Exocytosis
Endocytosis
Facilitated Diffusion
Protein Pump
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
water to move into the cell.
solutes to move into the cell.
water to move out of the cell.
solutes to move out of the cell.
Which means of particle transport requires input of energy from the cell?
diffusion
facilitated diffusion
active transport
diffusion
Diffusion occurs because
molecules are attracted to one another.
cellular energy pumps molecules across the cell membrane
molecules constantly move and collide with each other.
molecules are attracted to one another.
