/hich of the following are ways in which forming a biofilm can make a bacterial fection more difficult to fight off or treat? Choose all that apply. V Bacteria in biofilms can cause the immune system to attack human cells V Bacteria in biofilms can have increased antibiotic resistance Bacteria in biofilms can no longer move Bacteria in biofilms are difficult for white blood cells to engulf

The most highly likely source of the huge global problem of superbugs emergence is: slowed down antimicrobial agents' research because of limited funding. because of the experiment performed in the lab in the watched video of how to develop superbugs and what occurs in microbiology research labs are the main causes gut bacteria from intensively farmed animals are exposed to routine low dose of antibiotics present in animal feed of intensive farming overseas. poor food safety practices in some home kitchens. None of these answers applies.

Bacteria talk using: vibrations detected through a liquid medium. different concentrations of the same chemical. the same chemical used to produce the matrix of a biofilm. species specific variants of a basic type of chemical (a lactone).

Explain 4 approaches to preventing or limiting biofilms.

These structures allow a bacterium to move through an aqueous environment: spores cilia flagella capsules fimbriae

The Legionella bacteria grows best in  cold, running water. warm, stagnant water. cold, moving air. warm, non-moving air.

Which  of the following  statement  about  3 bacterial  cell wall  is incorrect  Peptidoglycan consists of  long polysaccharide chainscross-linked with  amino acids. The  cell wall establishes a bacterium as a coccus, bacillus, or spirillum.  The  cell wall is relatively  nonpermeable and  restricts the passage of sugars and amino acids. Gram- negative  cells have a membrane  both inside andoutside their cell walls.  Gram-positive cells have more peptidoglycan in their cell walls gram-negative cells

of bacteria. The Gram stain works because of differences in the O 1) cell membranes O 2) genetic characteristics O 3) capsules O 4) antigens O 5) cell walls

Teichoic acid is a major feature of which cell wall? O Fungal Viral O Gram-positive bacteria Gram-negative bacteria O O All of the options

A particular bacterium is said to have a streptococcus morphology and arrangement. What does this mean? the cells are rod shaped and occur in clusters the cells are round and occur in chains the cells are round and occur in clusters the cells are spiral and occur singular
