What has more bacteria toilet water or water fountain water?

User Avatar

Asked by Wiki User

Toilet water generally has more bacteria compared to water fountain water. This is because toilet water is often contaminated with fecal matter and can contain various pathogens. On the other hand, water fountain water is usually sourced from a clean water supply and is regularly monitored and maintained for cleanliness and safety.

What is a characteristic of bacteria that is key to keeping them under control?

User Avatar

Asked by Wiki User

One key characteristic of bacteria that helps to keep them under control is their susceptibility to antibiotics. Antibiotics are drugs that can kill or inhibit the growth of bacteria, making them an effective means of treatment. However, it is important to use antibiotics responsibly to prevent the development of antibiotic resistance.

What is a dead or altered viruses or bacteria that are used to stimulate the body to be on alert are called?

User Avatar

Asked by Ladygold5555

Dead or altered viruses or bacteria that are used to stimulate the body's immune response are called vaccines. Vaccines contain weakened or inactivated forms of the pathogen, or certain proteins or subunits of the pathogen, to trigger an immune response without causing the disease. This allows the body to recognize and fight the pathogen more effectively if encountered in the future.

What is the control center of a cell not found in bacteria?

User Avatar

Asked by Wiki User

The control center of a cell not found in bacteria is the nucleus. The nucleus contains the cell's genetic material, including DNA, and is responsible for regulating the cell's activities. Bacteria, on the other hand, do not have a nucleus; their genetic material is located in the cytoplasm.

When one bacterium split in the middle to form two bacteria what is it?

User Avatar

Asked by Wiki User

This process is called binary fission. Binary fission is a form of asexual reproduction in which a single bacterium divides into two identical daughter cells. It is the most common method of bacterial reproduction.

Configuration of the GFP inside bacterial cells?

User Avatar

Asked by Wiki User

Inside bacterial cells, the green fluorescent protein (GFP) is typically encoded by a gene that can be introduced into the bacterial genome or expressed on a plasmid. The gene consists of coding sequences that allow the production of the GFP protein, which fluoresces green when exposed to specific wavelengths of light. The gene is regulated by bacterial promoters and terminators to control its expression level. The GFP protein is then synthesized within the bacterial cell and can be visualized using fluorescence microscopy or other techniques.

Do bacteriophage means bacteria eater?

User Avatar

Asked by KyterriousJamesgp0050

Yes, the word "bacteriophage" literally means "bacteria eater" in Greek. Bacteriophages are viruses that specifically infect and replicate within bacteria, ultimately leading to their destruction. They are known for their ability to kill bacteria and are being investigated for their potential as an alternative treatment to antibiotics.

Do deodorants work by killing bacteria or disguising odor with fragrance?

User Avatar

Asked by Wiki User

Deodorants primarily work by disguising odor with fragrance. They contain chemicals that neutralize or mask the unpleasant smell produced by sweat. Antiperspirants, on the other hand, work by reducing sweat production and may also have antibacterial properties to decrease bacterial growth, which can contribute to odor.

Who created bacteria with artificial DNA molecule in 2010?

User Avatar

Asked by Wiki User

In 2010, scientists at the J. Craig Venter Institute, led by Craig Venter, created bacteria with an artificial DNA molecule. This breakthrough involved synthesizing the entire genome of the bacterium and transplanting it into a different bacterial cell, resulting in the creation of a new organism with the artificial DNA.

What are the end points of danger zone the temperature range at which bacteria multiply fastest?

User Avatar

Asked by Wiki User

The end points or temperature range of the danger zone, where bacteria multiply the fastest, are typically between 40°F (4°C) and 140°F (60°C). Bacteria multiply best in this temperature range, posing a higher risk of foodborne illness if food is left in this temperature range for too long. It is therefore crucial to keep perishable foods out of the danger zone and ensure proper food storage and handling.

How do bacteria show the characteristics of MRS GREN?

User Avatar

Asked by Wiki User

Bacteria show the characteristics of MRS GREN (Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition) by exhibiting the ability to move using their flagella or other appendages, cellular respiration that allows them to utilize energy, sensitivity to stimuli in their environment, growth through cell division, reproduction either asexually or sexually, excretion of waste products, and obtaining nutrition from their surroundings through various mechanisms such as absorption, photosynthesis, or chemosynthesis.

What is the kill time of alcohol antiseptics that kill microorganisms and how long should you wait before so that living bacteria are not carried into the body upon insertion of the needle?

User Avatar

Asked by Wiki User

The kill time of alcohol antiseptics can vary depending on the specific product and concentration. Generally, it takes about 30 seconds to 1 minute for alcohol antiseptics to effectively kill most microorganisms. It is important to allow sufficient drying time after applying the antiseptic before inserting a needle, typically around 30 seconds. This helps ensure that any living bacteria on the skin surface are eliminated, reducing the risk of introducing them into the body.
