Bacteria

Yes, most bacteria are too small to be seen with an ordinary light microscope. Bacteria are generally between 0.5 to 5 micrometers in size, which is below the resolution limit of a light microscope which is about 200 nanometers.

Treponema pallidum is a spiral-shaped bacterium known as a spirochete. It has a long, thin, coiled shape that allows it to move effectively within its host's tissues.

Bacteria, such as Lactobacillus, play a crucial role in making curd by fermenting the milk sugars into lactic acid, which gives curd its tangy taste and thick texture. These bacteria also help in breaking down proteins in milk, resulting in the coagulation and solidification of curd. Additionally, these beneficial bacteria help inhibit the growth of harmful bacteria, contributing to the preservation and safety of curd.

Yes, some strains of Micrococcus can produce a yellow pigment called "micrococcin." This pigment is often seen in cultures of Micrococcus luteus, a common species of the genus.

Bacteria are typically viewed with a light microscope, which allows for visualization of their general shape and structure. Electron microscopes are used for higher-resolution imaging of bacteria, providing more detailed information about their cellular components and ultrastructure.

Bacteria can protect themselves from a hypotonic environment by having a thick peptidoglycan cell wall. This wall helps prevent the cell from bursting due to the influx of water. Additionally, some bacteria have a protective outer membrane that provides extra stability in hypotonic conditions.

Contamination of bacteria in tuna can occur during processing and handling, especially if proper hygiene practices are not followed. Bacteria can also enter the tuna during harvesting and transportation if the fish is not properly handled and stored at appropriate temperatures. Inadequate cooking or storage of tuna can also contribute to bacterial contamination.

Streptococcus is a type of bacteria that are typically found in the throat and on the skin. They can cause various infections, including strep throat and skin infections. Streptococcus bacteria reproduce by dividing in two during a process called binary fission.

Comma bacteria, also known as Campylobacter, are a type of bacteria commonly found in the intestines of animals and birds. They can cause gastrointestinal infections in humans, often leading to symptoms such as diarrhea, stomach cramps, and fever. Proper food safety practices, like cooking meat thoroughly and avoiding cross-contamination, can help prevent infection.

To kill bacteria on clothing, it is recommended to wash them at a temperature of at least 140°F (60°C). This high temperature helps to break down and remove bacteria effectively during the washing process. It is important to also follow the care instructions on the clothing label to avoid damaging the fabric.

It is possible for a person to get reinfected with the same bacterial strain if they come into contact with the person who initially infected them, especially if the person is still carrying the bacteria. Practice good hygiene and take necessary precautions to prevent reinfection.

Bacteria responsible for ammonification, such as nitrosomonas, are attracted to sources of ammonia and organic matter, which serve as their energy and nutrient sources. These bacteria are also attracted to environments with favorable oxygen and pH levels to carry out the ammonification process effectively.

Bacteria responsible for ammonification include various species of decomposers such as Bacillus and Clostridium, as well as certain species of Proteobacteria. These bacteria break down organic nitrogen compounds into ammonia through the process of ammonification, which is an important step in the nitrogen cycle.

Paramecia cells are organism and can survive on their own. Sheep cells are not organisms- just cells and can't survive on their own. They are made up of the same things like a nucleus and ribosomes, ETC.

No, slime capsules are not found in animal cells; they are typically found in certain types of bacteria. Animal cells do not produce slime capsules as a means of protection or survival within their environment.

Prolonged heating of the slide can cause the slide to shatter.

Bacteria need to be motile in order to find food, escape harmful environments, and locate optimal conditions for growth and reproduction. Motility allows bacteria to move towards nutrients and other favorable conditions, ultimately increasing their chances of survival and proliferation.

Streptococcus pyogenes is a bacterium responsible for causing infections such as strep throat, skin infections, and in severe cases, invasive and life-threatening diseases. It is commonly known as the group A streptococcus bacteria. Treatment typically involves antibiotics to help clear the infection.

Our immune system fights invading bacteria through a variety of mechanisms, including phagocytosis by white blood cells, release of antimicrobial chemicals such as cytokines, and production of antibodies to mark bacteria for destruction. These processes help to slow down bacterial multiplication and ultimately eliminate the invading pathogens.

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.

Campylobacter moves by using flagella, which are whip-like tail structures that rotate and propel the bacteria through liquid environments. This allows Campylobacter to swim towards nutrients or away from harmful substances in its environment.

No. Antibiotics do not help viral infections such as the cold or flu. Antibiotics are specifically for helping with treatment of bacterial infections or for preventing bacterial infections and do nothing to an inanimate virus.

Gram-negative bacteria have an outer membrane made of lipopolysaccharide and proteins, which the Gram-positive bacteria are lacking. More multi-drug resistance is being recognized in this class of bacteria than previously, and they are becoming a formidable foe in the environment because of the lack of new antibiotics to treat infections.

No, bacteria cannot grow forever. They follow a typical growth curve consisting of lag, log, stationary, and death phases. Factors such as nutrient availability, space, and waste accumulation ultimately limit their growth.

Some methanogenic bacteria (which are anaerobic) do have flagella.
