are microscopic
are single celled
are multicelled
have shapes that include sphere, rod, and spiral
have shapes that include prism, cone, and spiral
have nuclei and membrane-bound organelles
do not have nuclei and membrane-bound organelles

Answer 1

The characteristics that describe bacteria include:

- are microscopic
- are single celled
- have shapes that include sphere, rod, and spiral
- do not have nuclei and membrane-bound organelles

Bacteria are typically unicellular organisms that can be observed under a microscope and exhibit a variety of shapes, including spherical (cocci), rod-shaped (bacilli), and spiral (spirilla). They lack a defined nucleus and membrane-bound organelles, distinguishing them from eukaryotic cells.
