<u>Explanation:</u>
The controlled variable is a type of variable whose value is kept constant during the experiment to get the desired or expected result. The difference between constant and a control variable is that the constant can never be changed.
However, the value of control variable can be changed but is kept constant with a purpose in an experiment to get the data. The controlled variable in a battery can be the multi meter that should be used for all the batteries.
The order should be..
Ask a question
State a hypothesis
Test a hypothesis

Answer:
Fungi most fungi produce cellulases.
Explanation:
Fungi are eukaryotic microorganisms, however unlike other eukaryotes. Their cell wall is made up of chitin instead of cellulose.
Chitin is a fibrous polysaccharide found in the exoskeleton of arthropods and the cell wall of fungi. where as cellulose is also a polysaccharide which is an important structural component of plant cell wall.
Since fungi are saprophytic they produce enzymes such as cellulases that will help in breakdown of cellulose for food.
They cannot have a cell wall made of cellulose.
