which of the following is FALSEA cell will shrink when the concentration of electrolytes is greater inside the cell than outside
the cell. Diffusion is the process whereby substances move from a high concentration of solute to an area of low concentration. Water follows the movement of electrolytes. Sodium and potassium move across cell membranes by means of special proteins.
A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell.
Explanation:
<em>When the concentration of electrolyte is greater inside the cell than its outside, water molecules move from the outside electrolyte into the cell leading to its expansion and turgidity. If the water movement continues, the cell may burst and release its contents in a process known as lysis.</em>
Hence, that a cell will shrink when the concentration of electrolytes is greater inside the cell than outside of the cell is false.
All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.
You will need to complete a Punnett square to answer this. Let's say tongue rolling is R and non-rollers are r. The heterozygous roller would be Rr and the non-roller would be rr. Rr x rr That yields two offspring with Rr (rollers) and two rr (non-rollers). The ratio is 2:2 or 50%. See the attached image for the completed Punnett square.
