Question

question 13 (2.5 points)
biofilms found in nature
contain only bacteria
are composed of multicellular organisms
are most often found on liquid surfaces
are communities of unicellular organisms
contain only closely related organisms
question 14 (2.5 points)
which organelle is correctly matched with its function?
vacuoles production of atp from carbohydrates
rough er synthesis of plasma membrane proteins

Explanation:

• Question 13: Biofilms are complex communities. They are not limited to bacteria (can have archaea, fungi etc.), not multicellular in the sense of being one - organism - many - cells (they are communities), not mainly on liquid surfaces (can be on solid surfaces too), and not only closely related organisms. Unicellular organisms form these communities.
• Question 14: Vacuoles are for storage (of water, nutrients etc.), not ATP production (that's mitochondria). The rough endoplasmic reticulum (rough ER) has ribosomes attached and is involved in the synthesis of proteins, including plasma membrane proteins.

Answer:

• Question 13: are communities of unicellular organisms
• Question 14: rough ER - synthesis of plasma membrane proteins
