A cell membrane is composed of a double layer of lipids in which many kinds of proteins are embedded. Many of these proteins act like gates, allowing only certain particles to enter or leave the cell. When a particle has to go against its concentration gradient through one of these gates, energy is supplied by the cell to the correct protein to move the particle through the membrane. A sodium-potassium ion pump is an example of a type of carrier protein that used a large portion of the cell's energy to move sodium ions through the cell membrane. Which of the following best describes the type of cellular transport in the picture above? (3pts)
Active transport, it requires energy and moves from high to low concentration.
Active transport, it requires energy and moves from low to high concentration.

continue to move across the membrane in both directions as seen in an isotonic environment.
move across the membrane to the outside of the cell as seen in a hypertonic solution.
move across the membrane to the inside of the cell as seen in a hypotonic solution.
stop moving across the membrane as seen in an isotonic environment.
Cell Transport — Use the following passage and data table to answer the question. An osmosis investigation was conducted using chicken eggs to represent cells with semipermeable membranes. The mass of each egg was measured to determine how much water diffused into or out of the eggs. The eggs were first soaked in vinegar to dissolve the shell. Each egg was then placed in one of three different solutions for 24 hours. The table below shows the results of the investigation. Data table: Solution; Average Mass of Eggs Before Soaking (grams); Average Mass of Eggs After Soaking (grams); Difference in Average Mass (grams); Percent Change in Average Mass. Corn Syrup (5% water): 98.6, 64.5, 34.1, -34.6. Distilled Water (100% water): 64.5, 105.3, 40.8, +63.3. Vinegar (95% water): 71.2, 98.6, 27.4, +38.5. Based on the experiment, which of the following can be inferred about cells with semipermeable membranes? (3pts)
Substances other than water may also cross the cell membrane.
Substances other than water may block pores in the cell membrane.
Water enters the cell when placed in environments of high water concentration.
Water leaves the cell when placed in environments with a low concentration of solutes.
