Mark an X for that plant in the data table.

Write a comment about the plant’s death in your lab notebook.

Exclude the plant when you compute the average height of the whole group of plants.

Exclude another plant from the other group to balance things out.

Answer 1

1. Mark an X for that plant in the data table.

2. Write a comment about the plant’s death in your lab notebook.

3. Exclude the plant when you compute the average height of the whole group of plants.

Explanation: Its these three because I got it right on the homework.

Answer 2

Option A, B and C

Step-by-step explanation:

In an experiment, if some of the plants die during the experiment, then it becomes essential to mark those plants. Marking will ease the work of identification at the end of the experiment.

However, if at the time of marking, reason for the death of these plants is known then that should also be mentioned side by side in a booklet for later research.

Now, while calculating the average height of the plants it will be best to remove the number of dead plants from the total number of plants or else disoriented readings will be obtained.

Hence, option A, B and C is correct
