Explanation:
Glucocorticoids are hormones of the family of corticosteroids that participate in the regulation of carbohydrate metabolism favoring gluconeogenesis and glycogenolysis; They also have immunosuppressive activity. Its regulatory action also extends to the intermediate metabolism of fats and proteins. Glucocorticoids are mainly produced in the adrenal cortex of humans and are cortisol, cortisone and corticosterone. Cortisol is the most important glucocorticoid in humans.
From the pharmacological point of view they are corticosteroids for systemic use whose reference drug is hydrocortisone, which at high concentrations can suppress the production of ACTH adrenocorticotropic hormone in the adenohypophysis.
Answer:
Option D, renewable resource
Explanation:
A renewable resource is the resource which can be replenished after every use. Or in general the time taken by it to replenish must be small. For instance, fossil fuels too are renewable but the time taken by them to renew is too high and hence they are also considered as non-renewable.
Also renewable resources can be used again and again.
Hence, option D is correct
Answer:cell is the basic unit of life.
A cell may be unicellular or multicellular
Explanation:
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
