How does bacteria survive?

By only inhabiting areas where the conditions remain constant and their environment isn't subject to frequent change.

Comfortable temperature for heat-loving bacteria?

Between 5 and 63 Celsius. That's why we keep food in a fridge below 5 Celsius and cook at over 63 Celsius. The temperature bacteria grow fastest at is 37 Celsius which is also human body temperature.

Does garlic kill bacteria?

Yes, vinegar DOES kill many bacteria and viruses, including many very dangerous ones that can be in food such as E. Coli O157:H7. It is probably good to use in the kitchen and other places that you may be worried about harsher chemicals like bleach getting into food.

Usefulness of microorganisms?

Well...
They digest your food and manufacture some of the vitamins you need. (like Vit. K)
They make bread rise and turn grapes into wine.
They make yogurt and cheese.
They break down organisms that have died (animals and plants) and turn them into fertile soil.
Many plants need them to fix nitrogen from the air (and we need the fixed nitrogen from those plants)
They feed a lot of animals (like whales)
We can use them to grow drugs (like insulin)
We use them to treat illness (like penicillin)
Algae produce a significant amount of the oxygen

There are thousands of reasons that we need microorganisms, these are just a few. :)

Why is a bacteria a prokaryote?

Bacteria are classified as prokaryotes because they lack a true nucleus and membrane-bound organelles. Their genetic material is located in a single loop of DNA within the cytoplasm, rather than being enclosed in a membrane-bound nucleus like eukaryotic cells.

What is citrobacter freundii complex?

Citrobacter freundii complex refers to 8 related species of bacteria from the Genus Citrobacter, including Citrobacter braaki, Citrobacter freundii, Citrobacter gillenii, Citrobacter murliniae, Citrobacter rodenticum, Citrobacter sedlakii and Citrobacter werkmenii. These species all have similar phenotypic and genotypic characteristics, and in most cases cannot be reliably identified using the standard phenotypic methods employed in the laboratory. Therefore the identification for any one of the above species is most accurately reported as "Citrobacter freundii complex" Please see the article entitled "What's in a Name? The Genus Citrobacter" in the related web link. The Genus Citrobacter are part of the family Enterobacteriaceae, which are gram negative enteric (found in the intestinal tract) organisms.

What is cause of Paralysis of Human Body?

Spinal cord injuries are caused when delicate spinal cord tissue is bruised, torn, or crushed. Spinal cord injuries can be caused by accidents, but can also be caused by diseases or disorders.

As many as 400,000 Americans are living with spinal cord injuries. Most spinal cord injuries occur between the ages of 16 and 30, and about 82 percent of those who experience spinal cord injuries are male. Motor vehicle accidents account for approximately 44 percent of all spinal cord injuries. Other common causes include: • Acts of violence, including those that cause knife and gunshot wounds

• Slips and falls

• Sports-related injuries, mostly diving accidents

• Trampoline accidents Results of Spinal Cord InjuryAfter the spinal cord has been injured, messages no longer flow through the damaged area, essentially cutting off information between the brain and certain parts of the body. Generally, the functions of the body located above the point of injury will continue to work with no loss of function, while the areas of the body located below the point of injury will be impaired. Impairment can include the following: • Motor deficit

• Sensory deficit

• Breathing difficulty

• Bowel and/or bladder dysfunction Spinal Cord Injury

Does common pund scum belong to kingdom plantae?

Its position in the systemic classification is : Class : Chlorophyceae Order : Conjugales Family : Zygnemataceae The genus Spirogyra includes about 300 species.

What are chlamydiae?

Chlamydiae are a phylum of bacteria that are obligate intracellular parasites. One of these is Chlamydia trachomatis, which causes the STD chlamydia (See related question "What is chlamydia?" for information on the STD.)

Bacteria in the chlamydia family that causes disease include C. trachomatis, C. psittaci, and C. pneumonia. There are other chlamdyia species that cause diseases in other animals, as well as species that cause no illness.

What do helpful bacteria do?

Helpful bacteria play a crucial role in maintaining a healthy microbiome in the gut and other parts of the body. These bacteria assist in digesting food, synthesizing essential nutrients, supporting the immune system, and preventing the growth of harmful pathogens. They contribute to overall health and well-being.

Some bacteria produce harmfull posions called?

Some bacteria produce harmful toxins called exotoxins, which are released by the bacteria into the surrounding environment. These exotoxins can cause a variety of harmful effects on the host organism, such as tissue damage or interference with cellular processes. It is important to be aware of the presence of these toxins when dealing with bacterial infections.

How much does the population in Africa decrease and increase each year?

The population in Africa increases by approximately 2.5% per year, which accounts for natural growth (births minus deaths) and migration. The rate of decrease is minimal and varies by country, often influenced by factors such as disease outbreaks, conflict, and emigration.

What causes haemophilus influenza?

Haemophilus influenzae can cause pneumonia, but it is not what causes influenza. Influenza is a disease that is caused by a virus. Haemophilus influenzae is the name of a bacterium. It was originally thought to be the cause of influenza before they had discovered viruses, that is how a bacterium got the name with "influenzae" in it. This type of bacteria also can cause meningitis, septic arthritis, and many other infections, commonly in children under 5 who have immature immune systems. It is a bacterium that can be present without causing illness, unless the person has a suppressed immune system.
when does influenza useally start

Can you get a staph infection from dirty haircutting implements?

Yes, it is possible to get a staph infection from dirty haircutting implements if they are not properly sterilized between uses. Staphylococcus bacteria can thrive on unclean tools and be transmitted to the skin during a haircut, leading to an infection. It is important for barbers and hairstylists to maintain proper hygiene practices to prevent the spread of infections.

What are three thing that make bacteria grow?

Three things that make bacteria grow are a suitable environment (temperature, pH, and nutrients), water for metabolic processes, and time for cell division and proliferation.

What eats bacteria?

Bacteria are consumed by various organisms including protists, fungi, and other bacteria. Predatory bacteria such as Bdellovibrio and Vampirococcus also feed on other bacteria by invading and using them as a food source. Additionally, bacteriophages, which are viruses that infect bacteria, can also help control bacterial populations.

How many identified species of bacteria are there?

4000 species known, but over 3million presumed to be living on the earth 4000 species known, but over 3million presumed to be living on the earth

What is bordetella avium?

How do you stop under arm bad smell?

Answer: Women are ahead of men on under-arm maintenance....eg. they know there is a relationship between smell and pit-hair. The hair has bacteria that outgases. Sometime look up a doctors sleeve ... many shave(per class study)....getting rid of the source of body odor. Deoderant is mostly a coverup.

What is the best condition for bacteria to grow in?

Bacteria grow best in warm, moist, nutrient-rich environments with a neutral pH level. The optimal temperature for bacterial growth is typically between 30-37 degrees Celsius. It is also important for bacteria to have access to oxygen, although some types of bacteria can thrive in anaerobic conditions.

What are the three different growth patterns of bacteria?

Diplo- is a prefix that refers to a paired arrangement of cell growth. The prefix Staphylo- describes an arrangement of cells that resemble grapes. Strepto- is a prefix that refers to an arrangement of chains of cells. ( hope this helps)

What do biologists study?

A biologist is a scientist devoted to and producing results in biology through the study of life. Typically biologists study organisms and their relationship to their environment. Biologists involved in basic research attempt to discover underlying mechanisms that govern how organisms work. Biologists involved in applied research attempt to develop or improve medical, industrial or agricultural processes.

What chemical is produced by fungi that prevents bacteria from growing?

Fungi produce compounds called antibiotics to prevent the growth of bacteria. One example is penicillin, which is produced by the fungus Penicillium. These antibiotics inhibit the growth of bacteria by interfering with their cell wall formation or protein synthesis.
