Both strands then form the template for free nucleotides to bind to to create the two identical daughter strands. Hence each daughter strand has half of the DNA from the original strand and half newly-formed DNA.  brainliest

a researcher wishes to know whether there is a significant difference in the number of knee injuries reported among four sports.
boyakko [2]

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.

⇔ Ability to rust wouldn't work as a physical property. That one changes the substance, making it a chemical change. So, we know that this can certainly be our answer!
