The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. In Pa
rt III, you will be investigating the questionable baseball. Use the drop-down menus to complete the sentences and identify the independent and dependent variables. In Part III, the independent variable, the one that is intentionally manipulated, is . In Part III, the dependent variable, the one that you measure the response in, is .
A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.
An Aldotetrose is a tetrose sugar (4 Carbons) with an aldehyde functional group on the first atom. The D- compound contains the last bottom asymmetric -OH group at the right side of the Fischer's projection. The L-compound contains the last bottom asymmetric -OH at the left side of the Fischer projection. So the Fischer's projection of the four aldotetroses is as follow:
