protista came from eubacteria whic came from archae bacteria whic has a prokharyotic cell this makes it multicellular and autotrophic and hetertrophic it was found from all of its small andcestors and was never found today. luckey it is still with us and we all aaws need bacteria
A safety precaution th researcher should take to avoid contact with bacteria?
Wearing appropriate personal protective equipment, such as gloves and a lab coat, can help prevent direct contact with bacteria. Additionally, ensuring proper ventilation in the laboratory and following established protocols for handling and disposing of bacterial cultures can further minimize the risk of exposure.
Explain the role of nitrifying bacteria in making nitrates available to plants?
Nitrifying bacteria convert ammonia, a form of nitrogen that plants cannot directly use, into nitrates through a two-step process. This conversion makes nitrates available for plants to take up and use as a nutrient for their growth and development. Nitrifying bacteria play a crucial role in the nitrogen cycle by facilitating the transformation of nitrogen into a form that plants can readily absorb.
What is the role of nitrifying bacteria in making nitrates available to plants?
Nitrifying bacteria convert ammonia (NH3) to nitrites (NO2-) and then to nitrates (NO3-), making nitrogen available in a form that plants can absorb and utilize for growth. This process is known as nitrification and is essential for the nitrogen cycle in soil, providing plants with a vital nutrient for their development.
Gonorrhea is a relatively common sexually transmitted infection (STI) worldwide. In the United States alone, there are approximately 1.7 million cases reported each year. However, the actual number of cases is likely higher due to underreporting and asymptomatic infections.
How do chemoautotrophic bacteria manufacture organic compounds without sunlight?
They oxidize inorganic compounds as a source of energy.
OR
Chemoautotrophic bacteria uses energy produced by oxidizing or reducing chemical substances. The energy released from oxidation or reduction is used to synthesize organic compounds. Hence they don't need sunlight.
This chemosynthesis does not and this is how it differs from photosynthesis.
Does bacteria algae plants or animals are the basic units of life?
Plants, animals, fungi, and protists are considered the basic units of life due to their complex cellular structure and ability to carry out life processes independently. Bacteria and algae are also living organisms, but they have simpler cell structures and are classified separately in the biological classification system.
Yes, Actinomyces is a Gram-positive bacteria commonly found in the oral cavity and gastrointestinal tract. It can cause infections in humans, particularly in the head and neck region.
Dormnat structures in bacteria formed in response to adverse conditions?
Bacterial endospores are dormant structures formed in response to adverse conditions such as nutrient depletion or extreme temperatures. They have a tough protective coat that allows bacteria to survive in harsh environments until conditions improve. Spores can germinate and resume growth when conditions become more favorable.
Is Chlamydia trachomatis considered an intracellular parasite?
Yes, Chlamydia trachomatis is considered an intracellular parasite because it lives and replicates within the cells of its host organism. It primarily infects epithelial cells and can cause a range of infections, including sexually transmitted infections and ocular infections.
Peas can be canned or frozen Which of these will contain living bacteria?
Peas that have been canned will not contain living bacteria, as the canning process involves high heat that kills any bacteria present. On the other hand, peas that have been frozen may still contain some living bacteria, as freezing does not fully eliminate all bacteria.
Can some bacteria exchange genetic material with each other using a thin tube to connect them?
Yes, this process is known as bacterial conjugation. During conjugation, a thin tube called a pilus allows the transfer of genetic material (such as plasmids) from one bacterium to another. This exchange of genetic material contributes to bacterial diversity and can lead to the spread of antibiotic resistance genes in bacterial populations.
Thrax holds a meeting with other bacteria and viruses in a club called what?
The club is called the Virus Vault.
Ture or false some bacteria can use the sun's energy to make their own food?
False. Bacteria are typically classified as heterotrophs, which means they cannot make their own food using the sun's energy through photosynthesis. Instead, they rely on consuming organic matter produced by other organisms.
What are the Factors that promote bacterial growth in foods?
The five conditions that bacteria loves to grow in is food left out for more than an hour or frozen food that has not been re-cooked to an even 165c in thickest part. Food can be contaminate making it harmful to eat at any time during growth, harvesting or slaughter, processing, storage, and shipping.
Who was the scientist who discovered the existence of Bacteria?
The scientist who is credited with discovering the existence of bacteria is Antonie van Leeuwenhoek. He used a microscope to observe microorganisms, including bacteria, for the first time in the 17th century.
How do you identify enterobacter gergoviae?
Enterobacter gergoviae can be identified through various laboratory tests such as biochemical tests, including API 20E or VITEK system. It typically does not ferment lactose and produces a characteristic pink-red pigment on certain media. Additionally, molecular techniques like PCR can be used to confirm the presence of specific genetic markers.
What foods do you find listeria monocytogenes?
Listeria monocytogenes can be found in ready-to-eat deli meats, unpasteurized dairy products, raw sprouts, and processed foods that have been contaminated during production or storage. It can also survive and grow in refrigerated temperatures. Ensuring proper food handling and cooking practices can help reduce the risk of listeria contamination.
How can you isolate Neisseria gonorrhea?
Neisseria gonorrhoeae can be isolated by collecting specimens from infected sites such as urethra, cervix, rectum or throat, and then culturing the organism on selective media like Thayer-Martin agar. Microscopic examination of the sample can also help identify the characteristic gram-negative diplococci. Molecular methods like PCR can also be used for detection and isolation.
If bacteria invaded the CNS tissue microglia would migrate to the area to engulf and destroy them?
Yes, microglia are specialized immune cells in the brain and spinal cord that respond to pathogens like bacteria by migrating to the affected area. They help to prevent infections and maintain the overall health and function of the central nervous system by engulfing and destroying invading microorganisms.
Which house hold item has the most bacteria?
Kitchen sponge typically has the most bacteria in a household due to its damp environment ideal for bacterial growth. Regularly disinfecting sponges or replacing them frequently can help reduce bacteria buildup.
Which bacterial agent is contagious person to person?
Bacteria such as Streptococcus pyogenes, Neisseria meningitidis, and Mycobacterium tuberculosis are examples of bacterial agents that can be transmitted from person to person through close contact, respiratory droplets, or bodily fluids.
What diseases are caused by mycobacterium smegmatis?
Mycobacterium smegmatis is not a major human pathogen and is considered non-pathogenic to humans. It is commonly used as a model organism in research due to its genetic similarity to other pathogenic mycobacteria.
Some bacteria are greenish in color and live on the surface of water These organisms are probably?
cyanobacteria, also known as blue-green algae. They are photosynthetic bacteria that can live on the surface of water and produce a greenish color due to their chlorophyll content.
