You use a special balloon that is permeable to water but not sucrose to make an "artificial cell." The balloon is filled with a solution of 20% sucrose and 80% water and is immersed in a beaker containing a solution of 40% sucrose and 60% water. The solution in the balloon is relative to the solution in the beaker.

a. hypertonic
b. hydrophilic
c. isotonic
d. hypotonic
e. hydrophobic

d

Explanation:

A Hypotonic solution contain lower solute concentration and higher free water concentration. While Hypertonic solution has a higher solute concentration and lower free water concentration. In the illustration above the artificial cell ''balloon'' contains less solute and more water than the surrounding solution (beaker) therefore the artificial cell solution is hypotonic to the surrounding solution.

When two solutions differ in osmolarity, the one with the greater concentration of solutes is said to be hyperosmotic, and the more dilute solution is to be hypoosmotic. Since the cell is impermeable to sucrose, water flows by osmosis from a hypoosmotic solution to a hyperosmotic one until the concentration of sugar is leveled of both sides.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
