A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
The pair that incorrectly matches polymer-monomer is lipids-monosaccharides (option C).
<h3>What is a monomer?</h3>
A monomer is a small molecule which can be covalently bonded to other monomers to form a polymer.
A polymer, on the other hand, is a large molecule made up of a chain of many monomeric units, formed by chemically bonding together.
The following are the monomer-polymer combination we have in nature;
- Carbohydrates - simple sugar/monosaccharide
- Protein - amino acid
- Lipids - fatty acid
- Nucleic acid - nucleotide
Therefore, the pair that incorrectly matches polymer-monomer is lipids-monosaccharides.

The endocrine gland cell will grow as an endocrine gland cell in the leg muscle when it is transplanted to a leg muscle.
<h3>What is determination of cell?</h3>
A fundamental part of cell determination is the ability of cells to detect different chemicals within different regions of the embryo.
One well-studied example of the molecular basis of cell determination and differentiation involves the development of mature muscle cells in vertebrates.
<h3>What is endocrine gland cell?</h3>
An endocrine gland is organ that makes hormones that are released directly into the blood and travel to tissues and organs all over the body.
Thus, what will happen to cell that has undergone determination to become an endocrine gland cell is the endocrine gland cell will grow as an endocrine gland cell in the leg muscle.

The clinical findings that correlate with M.K's chronic bronchitis involve abnormal arterial blood gases as specified by the partial pressure of carbon dioxide of 52 mmHg. It is because of the lack of gaseous exchange in the lungs, the carbon dioxide gathers in blood above the normal ranges of 38-42 mmHg. A Cough is the most commonly observed symptom.
