Answer:
D (Swell and Burst)
Explanation:
Pure water contains a very low concentration of solute materials, hence it is regarded as HYPOTONIC. Since the red blood cell contains intracellular fluid that contains more solutes than the extracellular pure water it is placed in, it is said to be HYPERTONIC in comparison with the pure water.
This difference in concentration between the extracellular solution (pure water) and the intracellular fluid (red blood cell) called CONCENTRATION GRADIENT facilitates the movement of water by OSMOSIS. Osmosis is the process whereby water moves across a semi-permeable membrane from a region of low solute concentration to a high solute concentration.
Based on this osmotic gradient, water moves from the extracellular solution into the cell, causing it to swell and eventually burst as a result of excessive water intake.
Answer:
Each cell in the body and its components - tissues and organs - is a functional and structural entity. As a result, examining cytology can aid in the differentiation of normal and afflicted cells, as well as the identification of the disease's etiology at the cellular level.
