The illustration shows a model of the transport of solute particles from outside the cell to inside the Inside of cell
Protein pump
High concentration
Low concentration
Energy
Outside of cell
What type of cell transport is modeled?
A
The model illustrates active transport because energy is required for solute particles to
cross the cell membrane,
0
B. The model illustrates diffusion because solute particles are moving from an area of higher
concentration to an area of lower concentration
C. The model illustrates facilitated diffusion because protein channels allow solute particles
to cross the cell membrane.
D. The model illustrates osmosis because water molecules are moving from an area of higher
concentration to an area of lower concentration,

A. The model illustrates active transport because energy is required for solute particles to cross the cell membrane.

Explanation:

Active transport is the transport of molecules from a region of lower concentration to a region of higher concentration. In other words, movement occurs against a concentration gradient.

Due to this, it requires energy in form of ATP for this movement to occur. Hence, based on this question, the model illustrates active transport because energy is required for solute particles to cross the cell membrane.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
