Group of answer choices
capsule plays role in transport process
capsule can retain water ; cells protected against drying/ dessication
capsule presence aids bacteria to better evade host defense cells
capsule functions as a passive defense barrier

none of the above is a false statement
What is an antibiotic?
it is any type of chemical that is toxic
it is a general disinfectant effective against most types of cells and viruses
it is a type chemical produced by a bacterium or fungus that has the potential to control the growth of another bacterium
allows exchange of organisms between your bacteria culture and the environment
it is a macromolecule produced by the vertebrate immune system that helps destroy foreign cells
Which of the following are mechanisms by which neutrophils are able to destroy microbial invaders?
Check All That Apply
They can engulf invaders, destroying them with their granules in a regular phagocytic process
They can explode in tissues, releasing their granules and DNA to create NETS for trapping and destroying invaders.
They can explode in tissues, releasing their granules and RNA to create NETS for trapping and destroying invaders.
They can degranulate, releasing their destructive enzymes that then destroy invaders in tissues.
They can fuse to form glant cells that more efficiently trap and engulf invaders.

- Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario. Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab.

- How does the skin function to protect the body from microbes? Multiple Choice It serves as an impenetrable barrier most places except on the soles of the feet where the skin is particularly thin. Sweat serves to help flush microbes away. It secretes lysozyme which has antibacterial properties. It serves as an impenetrable barrier due to layers of keratin infused cells. search aarrow_forwardSome bacteria produce the enzyme penicillinase, which breaks the beta-lactam ring in the penicillin molecule and converts it into penicilloic acid, which is harmless to bacteria. This is an example of which of the following mechanisms of antibiotic resistance? which option below is the answer? Destruction or inactivation of the antibiotic by the microbe Preventing penetration to the target site within the microbe Alteration of the drug’s target site(s) within the microbe None of the other four answers are correct Rapid ejection (pumping) of the drug out of the microbial cellarrow_forwardIn terms of microbial pathogenicity, molecular Koch's postulates are a set of experimental criteria that show: A microbe is the aetiological agent of a disease A gene encodes a product that contributes to disease A gene encodes a product that contributes to immunity to a disease A mutation does not contribute to diseasearrow_forward
