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.

Answer:
DNA polymerase makes a molecule of RNA from a DNA template
Explanation:
DNA polymerase is an enzyme involved in the process of DNA replication. DNA replication replicates or synthesizes a new DNA replicate from the parental DNA.
The enzymes mentioned in the question perform a specified function which is matched with their description except for DNA polymerase as this enzyme is responsible for adding nucleotides to the synthesizing strand from the template strand f DNA.
Thus, the selected option is correct.
