Question

multiple answer 1 point members of domain archaea and domain bacteria share many characteristics. in which two characteristics are archaea different from bacteria? select two answers. size, because archaea are too small to be observed without a microscope. habitat, because many archaea live in extreme environments that lack oxygen. presence of a nucleus, because archaea are eukaryotic. cell organization, because archaea are single - celled. cell structures, because archaea use different types of cell walls and cell membranes

Explanation:

Archaea and bacteria are both prokaryotes. Archaea have distinct cell - wall and cell - membrane compositions compared to bacteria. Also, archaea can inhabit extreme environments while bacteria have a wider range of habitats but archaea's extreme - environment adaptation is a key difference. Cell organization being single - celled is common to both, archaea are not eukaryotic, and size is not a defining differentiating characteristic.

Answer:

Cell structures, because archaea use different types of cell walls and cell membranes; Habitat, because many archaea live in extreme environments that lack oxygen.
