It is an example of Passive Transport because the process of Osmosis is where water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, little energy is required to carry out this process.
because a preditor started killing off the offspring
Its in a way both C and D as at cholesterol acts as a fluidity buffer that at high temps. the cholesterol makes the membrane less flexible and at lower temps. makes the membrane more fluid
