The answer is; Varicosities are recognized by the enlargement of the veins. Superficial veins are most likely involved because they have little support from surrounding tissues. The veins have become tortuous and dilated because of incompetent valves that allow the blood to pool, stretching the vein walls. The likely cause in this patient's case is her pregnancies, because the enlarged uterus exerts download pressure on groin vessels, restricting return blood flow to the heart.

Red blood cells are placed in a hypotonic solution.
Arada [10]

Answer:

If Red blood cell is placed in a hypotonic solution, the water moves into the cell. The cell swells and become turgid.

Explanation:

This is a type of osmosis. here plasma membrane of RBC works as semipermeable(only solute can move) osmotic membrane.

We all know that, osmosis is a process where liquid moves across semipermeable membrane from less concentration gradient to high concentration gradient.  

There are three types of solution in respect of the concentration of cell's cytoplasm. These are

  1. Hypotionic (when the solution is dilute than the conc. of cytoplasm). In this condition water moves into the cell and the cell become turgid. this is known as deplasmolysis
  2. Hypertonic ( when the solution is concentrated than cytoplasm), In this condition water moves out from the cell and the cell become flaccid. This is known as plasmolysis.
  3. Isotonic (when both the conc. of cell and solution are same). No osmosis takes place.

Describe the structure and function of a root hair cell
Nadya [2.5K]
Root hair cells absorb minerals and water from the soil.


The water absorbed by the root hair cells passes through the plant in xylem tubes, to then reach the leaves. The energy from the sun is then used to convert water(H2O) into hydrogen (H) and oxygen(O2).
