Question

one or more plants could die during the experiment. if that happens, how will you account for it? 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. which plant is being measured correctly? plant a

Explanation:

• For "Mark an X for that plant in the data table": This is a valid way to record the plant's death in the data table for tracking.
• For "Write a comment about the plant’s death in your lab notebook": Documenting the event in the lab notebook is a standard practice for noting anomalies.
• For "Exclude the plant when you compute the average height of the whole group of plants": Since the plant is dead and its data (height) is no longer valid for the group average, excluding it is appropriate.
• For "Exclude another plant from the other group to balance things out": This is incorrect as it introduces bias and is not a valid scientific practice.

So the correct options are:

• 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.

Answer:

• 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.
