The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
I can tell you that it is NOT B.
I got it wrong.
A. Intracellular
The pathway water takes to reach the xylem cells in which it passes through each cell of the cortex is the intracellular route.

Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
<span>A. Stimulus is the term used to describe what causes organisms to react to their environment. Stimulus is something that can provoke organisms to respond to the world around them. For example, if you put your hand on the stove, the stove is going to be the stimulus for you to get burned and move your hand from it because it will be to hot - that is going to be your reaction to the stimulus. Camouflage is a type of hiding mechanism, parasites are organisms, and homeostasis is equilibrium in an organism. </span>
