The answer for this question is C ✨
Although the total distance the impulse travels in the reflex arc is less than 3 meters. the time taken is more than 0.04 seconds and the time taken is more than expected because of Synapses or due to gaps between neurons.
Diagram displays the whole reflex arcs from the tip of the finger to the spinal cord and then back out to a closer muscle, possibly in the forearm or the arm. Because the signal doesn't have to go all the way back to the finger, the total distance is less than 3 meters. Considering that it just travels back a portion of the way, less than 3 meters, it takes. Let's see, it takes more than twice as long, therefore the query makes us think about why the delay. Where is the hold-up what is happening there, and the key to this is that the gray matter of the spinal cord doesn't truly contain mylin, despite the fact that we said it- accelerates electrical conduction through the axon in the nerves of the extremities. Mylin has a whitish color, which contributes to the white matter's appearance of whitishness. Thus, the electrical signal becomes slower.

Here are the answers:
1. WHAT YOU WILL BE LOOKING FOR AS EVIDENCE OF REACTION IN THIS EXPERIMET IS FORMATION OF OXYGEN BUBBLES.
This is because, the catalase enzyme on which this activity is based is an enzyme that speeds up the rate of decomposition of hydrogen peroxide in the cells, breaking it down to oxygen and water. Thus, when this reaction is taking place you will notice that bubbles will form in the test tube. These bubbles is the oxygen gas that is been given off. The presence of the bubbles indicate that the reaction is occurring.
2. YES, THE CATALASE ENZYME WAS PRESENT IN THE PLANT TISSUE THAT WAS TESTED.
The catalase enzyme is present in all plants. The plants need the enzyme to help them breakdown hydrogen peroxide into water and oxygen. This is because the hydrogen peroxide is very toxic to the plant cells and can destroy them, thus the hydrogen peroxide has to be broken down into water and oxygen immediately it is formed.
3. YES, THE CATALASE ENZYME WAS PRESENT IN THE ANIMAL TISSUE TESTED.
In animals, the catalase enzyme is found in great number in the liver. As a result of the metabolic reactions which occur in the liver, hydrogen peroxide is always produce in the liver. The hydrogen peroxide is very toxic to the liver cells and has to be getting rid of on an immediate basis. The catalase is the enzyme which breakdown the hydrogen peroxide into water and oxygen which are not toxic to the cells.
