Answer 1

Explanation:

Generally when people think of bacteria, they think of burgers tainted with E. coli that can make you sick or the bacteria that cause a child's dreaded ear infections. However, our bodies are actually teeming with bacteria—they cover our skin and line our lungs and digestive systems. It is estimated that humans have 10 times more bacterial cells than human cells in their bodies. Some of these bacteria are indeed harmful—they directly make us sick or they increase the risk that we will get diseases like colon cancer or obesity. But others are actually helpful and can help prevent a person from developing an illness, like inflammatory bowel disease.

A recently published paper explores another way that bacteria can be helpful: they can prepare the immune system to fight off viral infections.

Answer 2

Explanation:

Bacteria never have cilia and eukaryotic cells never have pili. The Three-Domain System of classification is based on differences in the structure of RNA (tRNA) molecules. One way archaea differ from bacteria is that archaea possess more peptidoglycan in their cell walls.
