Answer:
A) yes
Explanation:
First section of trip: 30 miles in 40 minutes
Second section of trip: 15 miles in 20 minutes
The formula for speed is distance over time 
Calculate the speeds for each section of the trip.
First:
k = d/t
k = 30miles/40minutes <= reduce fraction by 10 (30÷10 and 40÷10)
k = 3 miles / 4 minutes
Second:
k = d/t
k = 15miles/20minutes <= reduce fraction by 5 (15÷5 and 20÷5)
k = 3 miles / 4 minutes
Therefore there is a constant speed because both sections of the trip are driving at "3 miles / 4 minutes".
3 miles / 4 minutes can be also formatted as:
0.75 miles per minute.
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:
E=mc2
Explanation:
It explains that in their interiors, atoms fuse together, creating energy.
<span>B.reduces the greenhouse effect
The greenhouse effect is caused by GHGs in the air... carbon is one of these gases, so reducing your carbon footprint reduces the greenhouse effect</span>
