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
Peregrine falcons is the answer. Cheetah's come in 2nd.
I am a white bread I am but inside my fellow human and chewed in the mouth and breaks down my carbohydrates and then I become a boules then I am swallowed through the esophagus which pushes me to the stomach which then I digest into chyme and then the stomach secrets it’s juices to break down the protein then I’m pushed to the small intestine dejunume where liver secretes bile to gallbladder then gallbladder secretes it and stores it. Also the pancreas secretes also enzymes to break it down. Then intestine justices break me down then I am sucked up of my nutrients and put into cells and then my remains go to large intestine where water and minerals are absorbed and then I’m sent to the rectum then anus to land in a toilet water to take on a new journey. :) hope this helps so how
The given statement is False, it should read, "A theory and a law are already both supported by evidence and are equal, but they have different functions."
In the scientific method, a "Theory" and a "Law" are already both supported by evidence, but they serve different purposes.
The role of "Theory" in the scientific method is to provide a justification for the data collected through observations and results. As more data is gathered, it may be altered, enhanced, or even dismissed. While a "law" typically refers to an observed natural event that is true no matter how it is tested. It doesn't explain why the incident or event actually happened.
