1.Strep throat is primarily caused by the bacteria Streptococcus pyogenes.

2.The oldest life forms on Earth are believed to be single-celled microorganisms, such as bacteria and archaea.

3.Various types of bacteria can cause food poisoning, including Salmonella, Escherichia coli (E. coli), and Campylobacter, depending on the contaminated food source.

4.Pili or fimbriae are structures on the surface of bacteria cells that help them stick to surfaces.

5.Two foods that bacteria help make are yogurt (through bacterial fermentation) and cheese.

6."Decompose" means to break down organic matter into simpler substances, often carried out by bacteria and other decomposers.

7.The control center of a bacteria cell is the nucleoid, where the genetic material (DNA) is located.

8.Archaebacteria can live in extreme environments such as hot springs, salt flats, and deep-sea hydrothermal vents.

9.Common bacteria belong to the kingdom Monera (or Bacteria in the three-domain system).

10.Ribosomes are structures found in both bacteria cells and human cells, involved in protein synthesis.
