Answer:
The correct answer is - organ level organization.
Explanation:
The heart is made up of various types of tissues that include muscle tissue, nerve tissue, and blood tissue. All these types of tissues are organized to form the organ level organization which makes the heart is an organ.
Tissues are made up of cells and organs are made up of tissues and various organs combine together to do a specific function, this is an example of an organ system.
Thus, the correct answer is - organ level organization.
Answer:
Option B
Explanation:
Both the US industrialist John D. Rockefeller and Andrew Carnegie believed that the law of nature govern even the industrial , business or corporate sector. As in a wild forest, strongest animal survives by feeding the weak animals, like wise the business/industries/corporation of large size survive by feeding or eliminating the smaller ones. They think that this is not at all evil but it is as per the law of nature.
Thus, option B is correct.
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.
