Why would bacteria not grow on an agar plate treated with disinfected?
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.
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 is the most appropriate solution that would you use to disinfect the linens?
The most appropriate solution to disinfect linens would be to wash them in hot water (at least 140°F) with bleach or a disinfectant detergent. This will effectively kill germs and bacteria on the linens.
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 long must an object soak in disinfectant solution to be properly disinfected?
To properly disinfect an item, it would need to be saturated or immersed in a disinfectant solution for at least 10 minutes. But, 15-20 minutes would be better. If you are trying to sterilize the item, you would need to leave it soaking for at least half an hour.

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.

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 would act as a disinfectant?
warm water
Would bromine be an effective disinfectant and bleaching agent?
Yes, bromine can be an effective disinfectant in water treatment, swimming pools, and hot tubs due to its ability to kill bacteria and algae. It is also used as a bleaching agent, especially in the production of paper and textiles. However, its effectiveness can depend on the specific application and concentration used.

Why nitrogen is used as disinfectant?
Nitrogen is not commonly used as a disinfectant. Disinfectants are typically chemical solutions or agents that are specifically designed to kill or inactivate microorganisms. Nitrogen is an inert gas and does not possess disinfectant properties.
