Some of the equipment the student can use are:
Nets
Underwater cameras
pH indicators
among others.
<h3>What does the student want to study?</h3>
The student wants to find out if there are invertebrates and fish or if the conditions of the pond would support these types of organisms.
<h3>What does the student need to do?</h3>
In this situation, there are two main approaches:
- Study invertebrates and fish: This approach implies finding out if there are already invertebrates and fish in the pond, to do this, the student can
- Directly observe organisms by using a special camera.
- Use a net to catch organisms in the pond and then classify the organisms.
- Study the conditions: This approach implies determining if the pond has the conditions for invertebrates and fish to live. To do this, the student will need to measure conditions such as:
- Nutrients in the pond.
- Temperature.
- Ph.
This will require equipment such as pH indicators.

Answer:
0.00004524 minute
Explanation:
The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.
If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken
1.9/700 seconds and that is 0.0027143 second.
We're asked to convert to minute, we then have
0.0027143/60 which is equal to 0.0000452381 minute.
Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.
Plant cells have chloroplasts, a cell wall and vacuoles.
