Answer:
B. Solid rock breaks apart.
Explanation:
The following statement which best justifies the inclusion of test tube v as a control in the experiment is that it will show the color change that occurs in the absence of enzyme activity and is denoted as option C.
<h3>What is an Enzyme?</h3>
This is referred to as a biological catalyst which is involved in the speeding up of the rate of a reaction by lowering the activation energy used to initiate the reaction.
Enzymes are known as proteinous in nature and are denatured by heat and other substances is included in the test tube v as a control in the experiment is that it will show the color change that occurs in the absence of enzyme activity.
This therefore helps to differentiate the enzymatic processes which takes place in a substance or body therefore making option C the correct choice.

The options are:
- It will provide a measurement of amylase activity at an acidic pH.
- it will provide a measurement of amylase activity at a basic pH.
- It will show the color change that occurs in the absence of enzyme activity.
- it will show the color change that occurs in the absence of the amylase protein.
It will show the color change that occurs in the absence of enzyme activity.
Answer:
A negatively charged particle -q is placed at the center of a uniformly charged ring, where the ring has a total positive charge Q as shown in the following figure. The particle, confined to move along the x axis, is moved a small distance x along the axis ( where x << a) and released. Show that the particle oscillates in simple harmonic motion with a frequency given by,
