The answer is C. Eukaryotes
The answer is skeleton.
Please correct me if I'm wrong!! :)
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:
Characteristics of Fungi
Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.
They may be unicellular or filamentous.
They reproduce by means of spores.
Fungi exhibit the phenomenon of alternation of generation.
Fungi lack chlorophyll and hence cannot perform photosynthesis.
Answer:
Abiotic is basically a non living factor so the answer is
D. Sunlight, temperature , conductivity, dissolved oxygen.
All other options contain one biotic or living factor like algae, star fish and crabs these aren't Abiotic.
