Question
1.) Which term applies to two domains? A. archaeans B. eukaryotes C. bacteria D. prokaryotes
2.) The human ---------------------- (the complete collection of bacteria that live in and on our cells and bodies) affects human gut health, brains, and even body odor. This can be measured by citizen science projects where public participants are swabbed and bacteria grown in a lab.
(Microbiome/genome/proteome/transcriptome)
3.) Why might a bacterial cell that has both a capsule and pili be more pathogenic than a cell that does not have these cellular features?
A. The capsule helps disease-causing bacteria resist binary fission, and pili help the bacteria become resistant to antibiotics.
B. The capsule helps disease-causing bacteria replicate DNA faster, and pili help the bacteria secrete toxins faster.
C. The capsule helps disease-causing bacteria maneuver in sterile tissue, and pili help the bacteria become motile in the bloodstream.
D. The capsule helps disease-causing bacteria evade the immune system, and pili help the bacteria attach to surfaces, such as the cells of humans
