Answer:
This question is incomplete
Explanation:
Experimentally, when trying to determine the concentration of an unknown sample of CuSO₄ with known absorbance, a standard curve is used. The standard curve is a scattered plot/graph in which known concentrations and there respective/corresponding absorbance are plotted on a "X and Y axis" graph (scattered plot). The absorbance is represented on the y-axis while the concentration is represented on the x-axis.
Once this known values are plotted on the standard curve, an unknown value (either absorbance or concentration) can be extrapolated from the curve. What is missing from the question is data required for the standard curve.
This question shows the absorbance of the CuSO₄ has been determined (most likely using spectrophotometer), the concentration could have been extrapolated from a standard curve.
An example of a standard curve is provided in the attachment for guidance.
Answer:
Option (I) and (IV).
Explanation:
Fatty acids may be defined as the carboxylic acid that contains the long aliphatic chain. Fats are generally of two types - saturated fatty acid and unsaturated fatty acid.
The fatty acids are generally synthesized in the two carbon units. This helps in the proper synthesis of fat. The fatty acids that are most common in plants and animals are palmittic acid or the fats that contain C16 and C18 species predominate.
Thus, the correct answer is option (I) and (IV).
Answer:
D. X is eukaryotic and Y is prokaryotic
Answer:
"Autonomic nervous system" is similar to the autopilot of the airplane
Explanation:
The autonomic nervous system is a portion of the govern system which regulates the metabolic or the physiological processes of the human being. Inside the brain the autonomic nervous system is controlled by the hypothalamus. On the other hand the autopilot of the airplane is the combination of the system that are required for the automatic operation of the plane. Hence, both the things are similar but works for different process.
