your answer
which of these is not true about all organisms? *
all living things have many cells
all living things need water
all living things reproduce
all living things respond to stimuli
which of the following organisms belongs to kingdom protista? *
mushrooms
beetles

Explanation:

• For the first question, stimuli can indeed be external (like light or sound) or internal (such as hunger pangs), so it's true.
• For the second question, not all living things have many cells. There are single - celled organisms. All living things need water, reproduce, and respond to stimuli.
• For the third question, mushrooms belong to Kingdom Fungi and beetles to Kingdom Animalia. Protists are a different group of eukaryotic organisms.

Answer:

• A stimulus can be external or internal. T/F: T
• Which of these is NOT true about all organisms? *: All living things have many cells
• Which of the following organisms belongs to Kingdom Protista? *: None of the above (as mushrooms and beetles are incorrect)
