-
simple diffusion
-
filtration
-
translocation
-
reabsorption
A
Correct answer
Explanation
Unicellular organisms, such as Amoeba, rely on simple diffusion across their cell membrane to remove waste products directly into the surrounding environment.
-
mammals
-
plants
-
birds
-
amphibians
B
Correct answer
Explanation
Plants often store waste products in leaves, bark, or fruits, and then shed these parts to effectively remove the waste from their system.

Algae
-
Amoeba
-
Fungi
-
Bacteria
A
Correct answer
Explanation

-
Grasshopper
-
Planaria
-
Amoeba
-
Both 1 and 2
D
Correct answer
Explanation
Amoeba is a single-celled organism. Grasshoppers and planaria are multicellular animals, making option D the correct choice as it identifies that both 1 and 2 are not single-celled.
