Answer:
Carbohydrate, proteins, and lipids
Explanation:
<em>The organic molecules that can be derived from eating foods are carbohydrate, proteins, and lipids.</em>
<u>Carbohydrates are general derived from starchy foods such as grains, proteins are derived from eating of foods that are rich in proteins such as meat, milk, etc, while lipids are derived from eating fat/oil-based foods such as butter, avocados, etc.</u>
Nucleic acids are not derived directly from foods. They are monomers of proteins and hence, they are only derived from breaking down proteins.
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
<span>D. There would be much less precipitation and evaporation.
Much of the precipitation comes from the evaporation of water from the ocean and posterior condensations into clouds that go over the mountains. If the mountains were to be far from the ocean, there would be much less precipitation and, therefore, evaporation also. </span>
The list that is composed of substances that are widely used for many years without apparent ill effects is the GRAS. GRAS is an abbreviation for generally recognized as safe; it is an American food and drug adminstration designation where chemical or substance added to food is considered safe by experts, and therefore, it is exempted from the usual federal food, drug, and cosmetic Act.
carbohydrate are the largest organic molecules
