Percent error is a statistical tool used for evaluating precision. It is expressed as:
Percent error = | (experimental value - theoretical value) / theoretical value | x 100%
Experimental value represents the calculated value while the theoretical value represents the known value. A percent error value which is approaching zero means that your experimental value is close to the known value. Which can possibly mean that you have precise measurements. Calculations are as follows:
Percent Error = | (2.54 - 2.70) / 2.70 | x 100 =5.93%
Thus, the answer is b. 5.93%.
Under extreme temperatures Enzymes become inactivated or denatured. due to this reason there will be no change in Photosynthesis despite a change in Light intensity.
<span>Jackson
performed an experiment in which he analyzed the elemental components of
several unknown compounds. His results are shown in the table:

conclusion is :

B. Proteins have some amino acids that contain
sulfur, whereas most lipids, nucleic acids, and carbohydrates do not contain
sulfur.
