What type of chemical agent retards bacterial growth?
Antibiotics are chemical agents that retard bacterial growth by targeting specific components of bacterial cells, which can inhibit their growth or kill them. Examples include penicillin, tetracycline, and ciprofloxacin.
What type of instrument is available for measurement of bacterial growth on the basis of turbidity?
A spectrophotometer can be used to measure bacterial growth based on turbidity. It detects changes in light absorbance caused by the presence of bacteria in a liquid culture, with higher turbidity indicating more bacterial growth.
What are the real life examples of exponential functions?
Compound interest, depreciation, bacterial growth, radioactive decay etc.
What inhibits bacterial growth but does not kill bacteria?
Bacteriostatic agents inhibit bacterial growth by preventing their reproduction and division, but do not directly kill the bacteria. Examples include certain antibiotics, refrigeration, and desiccation.
What are the examples of chemotropism?
Examples of chemotropism include pollen tube growth towards ovules in plants, fungal hyphae growth towards nutrients in the soil, and bacterial movement towards sources of nutrients or away from harmful substances.
What is the difference between bacterial and anti bacterial hand wash?
Bacterial hand wash favors the growth of bacteria on the surface of the skin ( hands). On the other hand ( no pun intended) ANTI bacterial hand wash does not favor bacterial growth and in fact contains agents to prevent any bacterial growth on the hands.
What are some examples of using the scientific method in the community?
Cleaning your bad mouth is good example of science, in-fact Microbiology. Due to the growth of bacterial.
Can bacterial growth in urine result in false positive for methamphetamine?
No, drug tests are designed with things such as bacterial growth in mind.
During which phase of bacterial growth would penicillin be most effective?
Penicillin would be most effective during the exponential growth phase of bacterial growth.
How do you destroy bacterial growth?
by distorting it
How sound effect bacterial growth?
Sound significantly slows bacterial growth. In an experiment conducted in my college biology class, 6 dishes full of nutrient agar (bacteria food) were swabbed with bacteria from a students mouth and then closed and left to grow with music playing next to it. The bacteria that had music grew much, much less bacteria in the allotted time.
How does oxygen slow bacterial growth?
Oxygen slows bacterial growth by affecting the metabolic pathways within the bacterial cells. Aerobic bacteria require oxygen to produce energy through respiration, and when oxygen is limited, their growth is inhibited. Oxygen can also generate reactive oxygen species that damage cellular components, further inhibiting bacterial growth.
