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
The questions has missed the multiple options. The options are as follows:
(a) organ, organ system, cellular, chemical, tissue, organismal; (b) chemical, cellular, tissue, organismal, organ, organ system; (c) chemical, cellular, tissue, organ, organ system, organismal; (d) organismal, organ system, organ, tissue, cellular, chemical.
Answer:
Option (c).
Explanation:
The evolution of the complex organisms take several billion years. The evolution of the organisms starts from the basic level and then move to the complex forms.
The hierarchy determines the level of the organization. Cell is the basic level of organization. The cells are formed by the union of chemicals. The cell combine together to form tissue. Tissue combines together to form the organ then the organ system and finally the whole organisms.
Thus, the correct answer is option (c).
Leukotriene modifiers work by blocking the action of leukotrienes, one cause of the inflammation and nasal congestion associated with allergies. For those with allergies and asthma, leukotriene modifiers help keep bronchial tubes, airways to your lungs, from constricting.
