This simple bacteria cell has the same structure as more complex cells. it controls what comes in to and leaves the cell and also maintains homeostasis. it is the a) capsule. b) cytoplasm. c) membrane. d) wall.

The right answer is C) membrane.

The cell is a logical entity: it is a compartmentalized compartment by a cell membrane (or cytoplasmic membrane) in which are grouped all the living molecules (organelles and nutrients). Without this membrane these biomolecules would be diluted in the surrounding environment.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
