natima [27]
<span> If the concentration of blood is 0.5 M, and red blood cells that are bathed in blood neither shrink nor swell and burst, the concentration of cytoplasm of RBCs is A. 0.5m. An isotonic solution refers to two solutions that have the same water concentration on both sides of a membrane. So, cells in isotonic solution have the same water concentration as the isotonic solution and thus they will neither shrink nor swell and burst.

VikaD [51]

Answer:

1. You will be unable to smell

3. Your olfactory receptor cells will no longer be able to respond  to molecules trapped in the mucus.

Explanation:

The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.

The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.

If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.

Thus, Options-1 and 3 are correct.
