You decide to investigate if adding more enzyme will cause the reaction to proceed faster you set out to prove the
hypothesis: it more catalase is provided, then the rate of the peroxide reaction will be faster. what would be a good choice for
your independent variable?

3,5, and 10 g samples of liver

Explanation:

There are two types of variables which are used for scientific experiments.

A dependent variable can be described as the variable which is being measured or tested in an experiment. An independent variable can be described as the variable which is changed in the experiment to check if it has any effects on the dependent variable. An independent variable is the one which can be controlled.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
