QUESTION 22 These cell wall proteins allow many bacteria to adhere tightly to host cells, colonize, and resist flushing. This is used as a virulence factor by Bordetella pertussis, Helicobacter pylori, and Streptococcus pneumoniae, and Neisseria gonorrhoeae. This best describes what? Bacterial flagella and axial filaments. Bacterial cell surface proteins called adhesins. Bacterial capsules (glycocalyces). Bacterial invasions Bacterial pili.

QUESTION 40 Which best describes bacterial quorum sensing? A system that allows bacteria to transfer virulence factors from one bacterium to another by horizontal gene transfer. A system that allows bacteria to sense their own population density by communicating with each other by way of secreted chemical factors and behaving as a population rather than as individual bacteria. A system that enables bacteria to directly injecting bacterial effector molecules into the cytoplasm of the host cell in order to alter...

Choose the correct answer 1. Bacteria have a cell wall made up of polysaccharides and polypeptides. This helps scientists place them into groups. Another name for this chemical make up is the glycocalyx e. capsule b. pili d. peptidoglycan 2. Protists are part of the organisms that float on currents of water. They are a copepods c. plankton b. viruses d. none 3. Which organisms are able to fic nitrogen gas to make it usable for others? a...

answer all the questions answering one question is not helpful 1. A helper T cell is capable of helping another cell because it expresses a protein on its surface that binds to a different protein on the surface of the cell being helped. What are these proteins (on the T cell, and on the cell being helped)? CD28, and B7 TNF, and TNFR Class I MHC, and TCR CD40L, and CD40 CTLA-4, and B7 2. Helper T cells are restricted...

How does the hydrolysis of ATP (to ADP+P) alter proteins in a muscle cell to allow for contraction? A) Hydrolysis results in activation of myosin to the extended “ready” position. B) Hydrolysis results in activation of myosin to the flexed “bent” position. C) Hydrolysis results in the movement of tropomyosin so that actin active sites are revealed. D) Hydrolysis results in the breakage of cross bridges between actin and myosin.
