Answer:
separate DNA fragments according to their size.
Explanation:
Gel Electrophoresis of DNA demonstrates how DNA can be specifically cut into fragments by restriction enzymes and then can be separated by fragment size on an agarose gel.
C
The "Nucleus" contains the genetic information of the cell in the form of deoxyribonucleic acid (DNA) or chromosomes and thus, controls cell growth and multiplication. It is also the site of DNA replication (formation of an identical copy of DNA).
While the "Golgi apparatus", or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
The plasma membrane, because it's a selective permeable which means it only allows certain things in like sucrose.
Answer:
- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.
- The solutions are hypotonic to the solution in the potato cells.
Explanation:
According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.
Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
