What will happen if a gram-positive bacteria is placed in distilled water and penicillin?
no changes
What do Penicillin's do?
Penicillin is an antibiotic. Penicillin is used to treat many different types of infections caused by bacteria, such as ear infections prescribed by doctors for bacterial infections in woundsDestroys the cell walls of the bacteria allowing the bacteria's cytoplasm to exit the cell as well as allowing water and ions to enter, causing apoptosis of the bacteria.
What would happen if a suspension of bacteria is placed in a distilled water with penicillin?
eventually the bacteria would die because the penicillin would interfere with the ability to synthesize a cell wall thus the bacteria wouldn't divide. and the existing bacterial cell wall would lengthen and become frail. However, the bacteria must be gram-positive because they have cell walls composed of peptidoglycan, which is ideal for penicillin to attack.

What illness is penicillin prescribed for?
Penicillin is prescribed for numerous illnesses. In general penicillin is used as an antibiotic to kill bacteria. Penicillin is used against bacteria that contain a cell wall that is considered "gram positive", which means the cell wall is comprised of a thick layer of peptidoglycan. Penicillin chemically prevents the linking of protein subunits in the cell wall which means the cell wall can not be assembled. Bacteria are very dependant on these cell walls to maintain osmotic pressure within the cell (primarily due to their small size). If it can not create and maintain this cell wall the bacteria fills with water and bursts, destroying the cell. While gram-negative bacteria do respond to a minor degree to this mechanism of action, it would be considered less appropriate to treat a gram-negative bacteria infection with penicillin due to the
Does bacteria grow quickly with potential hazardous foods with water activity .85 or higher?
Yes
Why might it be harmful to change the flow of water in the everglades?
Bacteria
How did the precambrian animal change?
during the precrambrian era.....it was bacteria and water plants living
How do you dilute penicillin?
with 3.2 ml of water
Is still water in a pail a potential breeding places?
Yes. Many water-borne diseases exist and all you need is standing water for bacteria, viruses and other pathogens to grow and spread.
Is the evaporation of water a potential sign of a chemical change?
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
Why is gram negative bacteria less susceptible to osmotic lysis?
Because penicillin disrupts and destroys the peptidoglycan layer. Gram Negative bacteria have an outer membrane that blocks penicillin from getting to is peptidoglycan. Gram positive bacteria do not have this outer membrane, its peptidoglycan layer is out and exposed!!
