How the exposure to penicillin affects the survival of some bacteria in the population?
Exposure to penicillin can lead to the survival of antibiotic-resistant bacteria in a population as non-resistant bacteria are killed off, leaving behind those that have developed resistance. Over time, this can increase the prevalence of antibiotic-resistant strains within the population. It highlights the importance of responsible antibiotic use to prevent the emergence and spread of resistance.
What else can I help you with?
What does bacteria dislike?
Bacteria generally dislike extreme temperatures, high levels of acidity or alkalinity, lack of nutrients, and exposure to harmful chemicals or antibiotics. These conditions can inhibit their growth and survival.
How much bacteria gets killed from steam?
The amount of bacteria killed by steam depends on various factors such as temperature, exposure time, and bacterial species. Steam can be an effective method for killing bacteria as the heat can denature and destroy proteins essential for bacterial survival. However, some heat-resistant bacteria may require higher temperatures or longer exposure times to be effectively killed by steam.
Why the frequency of pencillin resistant bacteria can change over time within the population?
Due to bacteria reproducing quickly, their enormous numbers and the rapid transfer of genetic data there is great scope for mutation to occur. These newly formed bacteria are often non-sensitive to existing antibiotics.
Why is cell division important to single-celled bacteria?
Cell division is vital for single-celled bacteria as it allows them to grow in size, reproduce, and pass on their genetic material to future generations. This process ensures the survival and proliferation of the bacteria population.
does paper carry bacteria?
Yes, paper can carry bacteria, as it can accumulate microorganisms from various sources, including handling, environmental exposure, and contact with contaminated surfaces. Studies have shown that paper products, such as newspapers and packaging materials, can harbor bacteria, potentially leading to cross-contamination. However, the level of bacterial presence on paper typically depends on factors like the type of paper, its usage, and environmental conditions. Regular handling and exposure to moisture can increase bacterial survival on paper surfaces.
How does penicillin aid in the destruction of bacteria?
Penicillin works by inhibiting the formation of the bacterial cell wall, which is essential for the bacteria's survival and reproduction. This weakens the cell wall, causing the bacteria to burst and die.

Do bacteria require ATP for their survival and functioning?
Yes, bacteria require ATP for their survival and functioning. ATP is a molecule that provides energy for various cellular processes, including metabolism and growth, which are essential for the survival of bacteria.
Why do organisms need plants algae and bacteria for survival?
The organisms need plants, algae and bacteria for their nourishment. This ensures their survival.
How is antibiotic resistance bacteria an example of natural selection?
When a population of bacteria is bombarded with antibiotics, the 'weak' ones will die. The ones with some resistance built in will survive, and divide to form a new population of copies of themselves, or a resistant population. This in itself is survival of the fittest in a very pure form.
Why the frequency of pencillin resistant bacteria can change over time within the population?
Due to bacteria reproducing quickly, their enormous numbers and the rapid transfer of genetic data there is great scope for mutation to occur. These newly formed bacteria are often non-sensitive to existing antibiotics.
Do bacteria prefer acidic or alkaline environments for growth and survival?
Bacteria generally prefer neutral to slightly acidic environments for growth and survival.
Do bacteria require oxygen for their survival?
Yes, some bacteria require oxygen for survival, while others can survive in environments without oxygen.
Why is cell division important to single-celled bacteria?
Cell division is vital for single-celled bacteria as it allows them to grow in size, reproduce, and pass on their genetic material to future generations. This process ensures the survival and proliferation of the bacteria population.
What is penecillim made of?
Penicillin is made of of the Penicillium fungi which produces penicillin that causes cell wall destruction which in turn causes cell lysis.
