Diseases: Osteoporosis & Scoliosis
Injuries: Open fracture, Avulsion fracture & Bowing fracture
Answer:
Option A
Explanation:
The concentration of salt is lesser than the concentration of salts in the solution. The membrane of the cell is permeable and hence it shall allow movement of salt ions towards the region of lower concentration from the region of higher concentration in lieu to the concentration gradient formed (supported by differences in concentration of salt within and outside the cell). Like the movement of salt, the water shall also move from region of high concentration to region of low concentration and thus water will move out of the cell thereby shrinking it.
Hence, option A is correct
Answer:
b. Proteins
Explanation:
Several transmembrane proteins serve as transport proteins and move charged, polar and large substances such as ions, amino acids, sugars through membranes. These are the carrier proteins and channel proteins. Each type of transport protein transports a specific type of substance. Carrier proteins bind the ion or molecule and undergo changes in shape. This change moves the molecule across the membrane. Channel proteins form pores through the membrane to allow transport of substances.
For example, aquaporins are transmembrane proteins that allow water to pass through membranes.
