Answer:
c) Both of the parents' genotype must have been Pp.
Explanation:
A plant breeder is trying to develop more purple colored violets. She knows the purple violets she has can be PP or Pp for the purple color. She crosses two purple violets. Of the four plants that result, one is white and three are purple. Obviously, the parents' genotype must have been Pp.

Both saline and NaCl solutions can be grouped as salt solution.
So by the given percentages, we can conclude that the cell has a higher water potential than the solution because it has a lower salt concentration.
In this case, the water molecules will flow from the cell to the solution, down the water potential gradient due to osmosis.
Osmosis is always the flow of water molecules from the region of higher water potential to a region of lower water potential through a semi permeable membrane, which is the cell membrane.
Since so much water is lost from the cell, the cytoplasm will shrink and detach from the cell wall. When this happens, we call this phenomenon plasmolysis.
So the answer should be the cytoplasm shrinks and detach from cell wall.
Answer:
materials/out
Explanation:
Physical limits on the flow of <u>materials</u> into and <u>out</u> of the cell prevent most cells from being too large.
<em>The limitation of the kind and amount of materials that flow into and out of the cell prevents the cell from being too large. The function of selectively allowing materials to enter and leave the cell is carried out by the cell membrane. While being permissible to some materials, it shuts some materials off and, thus, the size of the cell is maintained. </em>
