I belive its called Endosteum.
Natural selection: organisms with certain inherited traits that are more likely to survive and reproduce than others.
These favorable traits can give an organism an advantage by giving them a higher chance of survival and reproduction. Darwin called this, "survival of the fittest"
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
Answer:
Proteins are a class of macromolecules.
Explanation:
Proteins are a class of macromolecules, that can perform a diverse range of functions for the cell. They help in metabolism by providing structural support and by acting as enzymes, carriers or as hormones. The building blocks of proteins are amino acids.
Answer:
Interactions between cells always involve a structure known as a connexins.
Explanation:
Connexins is composed of specific type of protein called transmembrane proteins. This structure is responsible for the interaction between the cells. Cells communicate with each other by secreting specific chemicals in which information is present. These chemicals consist of neurotransmitter and harmones.
