(Next time please insert a picture of The graph regarding to your question)
Answer: The answer is (A)
Explanation:
QR- Liquid Only
RS- Phase Change Liquid-Gas
ST-Gas Only
This graph does not begin in the solid phase of water. It begins at 40 degrees Celsius in the liquid phase. Plateaus are phase changes. In this case, it’s a phase change from liquid to gas.
Answer:
A compound microscope
Explanation:
A compound microscope is an instrument used to view the structure of the microscopic organism using the light source and the lenses.
The compound microscope contains an eyepiece which contains the ocular lens and the objective lenses n the nosepiece closer to the specimen.
To view the living organism of the ponds, a compound microscope especially a bright field microscope is used when the light from the lower portion brightens the sample and the object appears darker.
Thus, the compound microscope is the correct answer.
The anwer is that they are conductors
To measure cross-linking amino acids in a collagen hydrolyzate using a conventional amino acid analyzer with ninhydrin detection, the bulk amino acids must be largely removed to avoid plugging the reaction coil. Tissue is thoroughly reacted with sodium borohydride to convert all intermediate cross-linking residues to their reduced, acid-stable forms. More vigorous reduction conditions may be used than when preparing profiles of tritium-labeled cross-links using NaB3H4<span> and direct amino acid analysis. </span>
