Bacteria

The presence of bacteria in dental unit waterlines was first reported in the late 1970s and early 1980s. Studies found that dental waterlines were contaminated with various microorganisms, including potentially pathogenic bacteria.

round cells are round discs with two large dimples at each side, and they are known as red blood cells. Their job is to carry oxygen to all your cells. The rounded shape gives extra surface area for picking up and carrying oxygen.

You will test it by before wiping the doorknob with the antibacterial wipe, use a cotton swab and wipe it around the door knob.... use agar and wipe the swab into a petri-dish with the agar. After wiping the doorknob using the antibacterial wipe, use another cotton swab to wipe the doorknob then wipe it into another petri-dishagar= helps grow

Yes, spirilla bacteria can get energy through various methods such as photosynthesis, chemosynthesis, or by breaking down organic matter through fermentation or respiration.

There are primarily four types of bacteria found in the reticulo-rumen of ruminants like cows and goats: cellulose-digesting, hemicellulose-digesting, starch-digesting and lactate-utilizing bacteria.

Neisseria gonorrhea is typically curable and causes no long-lasting effects is treated promptly. Antibiotic resistance is an increasing problem, so patients must follow instructions for treatment.

Bacteria reproduce rapidly, with some species able to double their population every 20 to 30 minutes under ideal conditions. This exponential growth results in a graph that shows a steep upward curve as the population increases over time.

Bacillus mesentericus is a bacterium commonly found in soil and the intestinal flora of animals. It is known for its ability to produce endospores that are resistant to harsh conditions, allowing the bacterium to survive in various environments. Some strains of B. mesentericus have been used in food fermentation processes, but it is important to note that not all strains are safe for consumption.

The simplest answer is that prokaryotic cells do not have a membrane-bound nucleus, and eukaryotic cells do. The nucleus is a compartment where the cell stores its genetic information (DNA). Prokaryotes' DNA is simply within the cytoplasm.

Another simple difference is that eukaryotes have membrane-bound organelles, whereas prokaryotes lack this feature.

3.5 Billion Years Ago. This is how old fossil stromatolites have been dated. You can find modern versions of these same formations growing now off the coast of Australia.
About 3,500 million years ago.

Bacteria are the most abundant organisms in the world. Scientists believe that bacteria helped create the earth's atmosphere. By producing so much life-producing oxygen, bacteria eventually made the atmosphere habitable for all creatures, including humans.

Bacteria are importnant to the planet as decomposers of dead organic matter, processors of nitrogen, and makers of medicine

No, amebiasis is not caused by bacteria. It is an infection caused by a parasite called Entamoeba histolytica.

Cyanobacteria can utilize sunlight through photosynthesis to produce energy, allowing them to live in environments lacking organic nutrients. They can also fix atmospheric nitrogen, enabling them to obtain essential nutrients for growth. Additionally, cyanobacteria can form symbiotic relationships with other organisms to obtain nutrients in nutrient-poor environments.

Yes, bacteria can be found in all three environments – air, soil, and the human body. In the air, bacteria can be carried by dust particles or released from soil or water sources. In soil, bacteria play essential roles in nutrient cycling and decomposition. In the human body, bacteria are present in various locations, such as our skin, gut, mouth, and other mucosal surfaces, where they can be beneficial or harmful depending on the specific species and context.

Halophiles disientergrate within themselves and produce chemicals like glucose to help them survive. Halophiles were discovered on eearth rouhly 2200 years ago and ancient scientists put salt into the cells to record the results. From then on the offspring of this Halophiles can live in salt. This means that the legacy of these scientists will live on for evermore.

their could be many different types of bacteria and no one knows for sure how many there is

Bacillus subtilis generally has a neutral smell. It doesn't have a distinct or strong odor.

Boils are generally caused by bacterial infections, most commonly by the Staphylococcus aureus bacteria. The bacteria usually enters the body through small cuts or hair follicles on the skin, causing an infection that leads to the development of a boil.

The three short chain fatty acids produced are acetate, propionate, and butyrate. These SCFAs play important roles in supporting digestive health, providing energy to colon cells, and influencing various physiological functions in the body.

Vent tubeworms provide a stable environment and chemical compounds for chemosynthetic bacteria to thrive while the bacteria convert chemicals from the hydrothermal vent into energy for the tubeworms. This symbiotic relationship allows both organisms to obtain essential nutrients and energy from an otherwise harsh environment.

When insulin was being commercially produced in genetically engineered bacteria and yeast, it was obtained from the pancreas of pigs and cows. This animal insulin was then purified and used as a template to create synthetic human insulin through genetic engineering processes.

Cyanobacteria is classified as monera, specifically within the kingdom Monera. They are prokaryotic organisms, lacking a true nucleus, and are commonly referred to as blue-green algae.

Staphylococcus aureus reproduces through asexual means, specifically through binary fission where a single cell divides into two identical daughter cells. There is no sexual reproduction involved in the life cycle of this bacterium.

Paramecia belong to the classification of protists known as ciliates. Ciliates are characterized by the presence of hair-like structures called cilia, which they use for movement and feeding.
