The correct answer is "three groups of plants—a group fertilized by X, a group fertilized by Y, and a control group with no fertilizer".
Explanation:
I had to look for the problem to know the options.
The best way to determine which fertilizer is most effective is to have three evaluation groups. One group will be tested with fertilizer X and another with fertilizer Y. By leaving the third group without applying fertilizer, this will be the general pattern for comparing the effectiveness of the other two.
Have a nice day!
Answer:
Structural
Explanation:
Isomerism is the existence of two or more compounds with the same molecular formula but different molecular structures due to the difference in the arrangement of atoms or spatial orientation of atoms.
Isomers have the same molecular formula but differs in their structural arrangement.
In organic chemistry, Isomerism can orginate from different arrangement of atoms.
It can be carbon chain length known as chain isomerism. Here, the carbon length is changed and arranged in different ways.
We can also have position isomerism which entails the position of the functional group in the structure.
It can also be functional group isomerism which deals with the possible arrangement of the group on the chain.
