Explanation:
A good way to reduce acid rain is use less fossil fuels, as they cause pollution which results in acid rain.
A small change in a persons DNA can cause any number of mutations that may be completely harmless or fatal depending on where the mutation (change) occurs in ones DNA.
For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive). ... If the acceleration is great, then the line slopes up steeply (i.e., the slope is great).
Positive control is Ginger root (should indicate the presence of amylase)
Negative control is Cellulose (should not contain amylase)
Here the presence of amylase is tested by testing the presence of starch using an IKI solution. Saliva is included in this experiment because it contains the enzyme amylase.
