Answer: The required [a] for slotion will be -62.7
Explanation:
The specific rotation of pure quinine= -165
% of pure quinine= 69%
% of its enantiomer=ee=31%
Enantiomer excess =(ee)=excess of a single enantiomer/entire mixture×100
Now,
Excess of a single enantiomer=69% - 31%=38%
Entire mixture=69% + 31%= 100%
(ee)=38/100 × 100
=38%
Net rotation= 0.69-0.31=0.38
Hence, [a] for solution will be = -0.38×165= -62.7
Anatomical and physiological barriers provide the crucial first line of defense against pathogens. These barriers include intact skin, vigorous mucociliary clearance mechanisms, low stomach pH and bacteriolytic lysozyme in tears, saliva and other secretions.
Answer: Option A "Loss of body fluids"
Explanation:
When the body lose blood or other fluids from the body, then the amount of blood in the body is reduced. The Hypovolemic shock happens when a sudden loss of body fluids takes place which is extremely dangerous.
Example:
At the time of delivery, there is blood loss from the body. At the time of injury there is a loss of blood from the body. These processes leads to loss of blood and body fluids.
In case of extensive burns leads to loss of body fluids.
Hence, the correct answer is option A.
<u>To prevent image </u><u>magnification</u> increased target-receptor distance required in the paralleling technique.
Magnification- A microscope's capacity to generate a picture of an item at a scale that is bigger (or even smaller) than its real size is known as magnification.
Target- A drug target is a biological molecule, often a protein, that is inherently linked to a certain disease process and that a medication might target to have the intended therapeutic effect.
Paralleling technique- The parallel method is the alignment of the central axis of the X-ray source so that it is perpendicular to both the plane of the film and the object being investigated. Unfortunately, it is considerably simpler to align the X-ray central axis perpendicular to the film than to the object.
