Bacteria would not grow on an agar plate treated with disinfectant because disinfectants are designed to kill or inhibit microbial growth. They disrupt essential cellular processes, such as protein synthesis and membrane integrity, rendering the bacteria unable to reproduce or survive. Additionally, the residual chemicals from the disinfectant create an inhospitable environment for bacterial growth, preventing colonization on the agar plate.

Why would bacteria not grow on an agar plate treated with a disinfectant?
Bacteria would not grow on an agar plate treated with a disinfectant because disinfectants contain chemical agents that are toxic to microbial cells. These agents disrupt essential cellular processes, such as protein synthesis and membrane integrity, leading to cell death or inhibition of growth. As a result, the disinfectant creates an environment that is unfavorable for bacterial survival and proliferation.
Describe the aseptic technique that would be used when flooding the agar plate with bacteria?
An agar plate was flooded with a culture of a species of bacterium usually found in the mouth. Four steriled paper discs, A, B, C, and D, each containing a different brand of mouthwash, were then placed on the agar plate. The drawing shows the appearance of the plate after it had been incubated below body temperature for three days, this is to ensure that the bacteria are not harmful to humans.

What happens when tap water is treated with alum?
the dirts and bacteria in the water would coagolate or clump together~it is also a method of purifying water..
How do you grow bacteria in broth and argar?
To grow bacteria in broth, you would add the bacteria to a sterile liquid broth, incubate it at the optimal temperature for growth, and periodically check for bacterial growth by observing turbidity or colony formation. To grow bacteria on agar, you would spread the bacteria on a sterile agar plate using a spreader, incubate it at the optimal temperature, and observe colony formation.
What safety symbols would appear on a an agar plate of bacteria culture?
An agar plate of bacteria culture would typically display safety symbols such as the biohazard symbol, indicating the potential presence of infectious agents. Additionally, the caution symbol may be included to warn about the handling of potentially hazardous materials. If any chemicals are used in the process, the toxic or corrosive symbols could also be present to highlight risks associated with those substances.

How would you change the bacterias plate to best tell if they are ampicillin resistant?
The best test would be to take some of the bacteria growing on the LB plate and streak them on a LB/amp plate. If the bacteria are viable on the LB/amp plate, then they are resistant to ampicillin. If no bacterial colonies survive, then they were not ampicillin resistant.
How Cultivation of bacteria?
To cultivate bacteria, you would typically streak a sample onto a nutrient agar plate in a sterile environment. The plate is then incubated at the optimal temperature for the specific bacteria species to grow. After incubation, colonies of bacteria will form, which can be studied and analyzed.
What would you need to do to determine whether bacteria growing on a petri plate are anaerobes?
some sense
What one plate would you first inspect to conclude that the transformation occurred successfully Why?
If you transform bacteria with a plasmid containing a selection marker (such as an antibiotic resistance gene) and plate the transformed bacteria on a plate suited for selecting for plasmid-containing bacteria (such as a plate containing an antibiotic that only those bacteria with antibiotic resistance can survive), then simply inspecting whether colonies are present on the plate will suffice in determining whether the transformation succeeded. If no colonies are found, that means no bacteria got the antibiotic resistance gene on the plasmid and the transformation was unsuccessful. If some colonies are found, that means some bacteria contain the plamis containing the antibiotic resistance gene and those colonies can the transformation was successful.
Why do horses stables need disinfecting?
Bacteria or viruses that could be rubbed off. Hand, foot and mouth disease for example. Really horrible I would know from having it personally, so stables and everything have to be kept disinfected.

What type of cardiovascular diseases may be treated with antibiotics?
Pericarditis, Endocarditis, and Myocarditis. All of these are inflammation diseases of the heart and if it is caused by bacteria, then it can be treated by antibiotics, because antibiotics clear up infections/bacteria.
What does hydrogen peroxide do for a horse wound?
Don't take me for certain here but as i remember hydrogen peroxide is used for healing and disinfecting. keeping a wound clean from bacteria and etc. So my best guess would be that it would keep your horse's wound disinfected and help it heal up better.
Can fish be given as solid food to 7 month old baby?
No because it would be to big for his or her mouth and it would have to be disinfected

What would happen if you left bread to go mouldy in an air tight container?
It would go mouldy because of the bacteria already present on it, however if you somehow disinfected the bread while it was in the container, it would not go mouldy, it would simply go dry and hard as rock. The only real way you could do this is by heating it up to 180+ degrees C while in the container.
