The correct answer is water. Since carbon
is the common element of organic compounds, the molecule of
an organic material must have at least one carbon atom in its molecule. Water does not
contain any carbon atom in its molecule, H2O. So water is only an inorganic compound. <span>It is the most abundant and important inorganic compound in
living material. It makes up about 60-80% of the volume of most living cells.</span>
um i believe its the skin cell?
A contact lens is a lens placed on the cornea of the eye.
Importance of buffers in contact lens products:
Buffers: They aim to keep the pH of the solutions at values between 6.6 and 7.8 in order to maintain the lens parameters and the effectiveness of the solutions. They are made by the combination of an acid and its sodium salt (phosphate and acetate for example). Borate and citrate buffers are used.
Importance of isotonicity in contact lens products:
The solution composed by isotonic saline solution.
Isotonia is expressed by osmolarity or cryoscopic lowering
- 0.236 to 0.446 mOsmoles / l (increases during the day)
- If the osmolarity of the mixture is different from that of the tears, it causes discomfort and irritation
• Increased tear secretion
• Increase the blink frequency
- If hypotonia, entry of water to the epithelial cells, if hypertonia: inverse
- Osmolarity restored 1 or 2 minutes after instillation
Yes it is a requirement for liquids to do that
DNA directs the cell that how it has to be function in a particular manner
