Answer:
Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.
Explanation:
The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.
<em>In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.</em>
To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.

Metabolism: all chemical reactions within a cell
That is the corrext answer
The right answer is a. synthesis of energy-rich sugars.
With chlorophyll, green plants absorb the light energy needed to synthesize an organic chemical species, glucose C6H1206, from carbon dioxide and water vapor. Each billion tons of the carbon element C are fixed by the green plants in the form of glucose. The reaction, called photosynthesis, also produces dioxygen and helps to regenerate this chemical species necessary for the breathing of living beings.
