What bacteria live in deep thermal vents?
Bacteria found in deep thermal vents include thermophiles and hyperthermophiles, such as species of bacteria from the genera Thermococcus, Methanococcus, and Methanopyrus. These bacteria are adapted to survive in extreme heat and pressure conditions typically found in deep sea hydrothermal vents. They play a key role in the ecosystem by converting chemicals like hydrogen sulfide and methane into energy through a process called chemosynthesis.
What is example of chemosynthesis?
Chemosynthesis is the conversion of carbon molecule(s) and nutrients into organic matter. An example of this is hydrogen sulfide chemosynthesis. This is a process used by giant tube worms, and produces sulfur.
Bacteria and debris are actively removed from the lymph by?
specialized cells called macrophages. These cells engulf and digest bacteria, debris, and other foreign particles present in the lymphatic fluid as it passes through lymph nodes. This process helps to protect the body from infections and maintain the integrity of the immune system.
Does dry seeds respire?
Yes, dry seeds can respire at a low rate through a process known as internal respiration. However, this respiration is minimal as the seeds are in a dormant state and not actively metabolizing. Once the seeds are exposed to water and conditions suitable for germination, respiration rates increase as cellular processes resume.
The process by which one strain of bacteria is apparently changed into another strain is called what?
The process by which one strain of bacteria is apparently changed into another strain is called bacterial transformation. This process involves the uptake and expression of foreign DNA by bacteria, leading to genetic changes.
What bacteria live in deep thermal vents?
Bacteria found in deep thermal vents include thermophiles and hyperthermophiles, such as species of bacteria from the genera Thermococcus, Methanococcus, and Methanopyrus. These bacteria are adapted to survive in extreme heat and pressure conditions typically found in deep sea hydrothermal vents. They play a key role in the ecosystem by converting chemicals like hydrogen sulfide and methane into energy through a process called chemosynthesis.
What bacteria obtain energy by stripping hydrogen and electrons from ammonium ions?
Nitrosomonas is a bacteria that obtains energy by oxidizing ammonia and stripping hydrogen and electrons from ammonium ions in a process called nitrification.
What do chemosynthesis bacteria do with hydrogen sulfide?
Chemosynthesis bacteria use hydrogen sulfide as an energy source to convert carbon dioxide into organic compounds in the absence of sunlight. This process allows these bacteria to survive in extreme environments such as hydrothermal vents or deep-sea thermal vents.
Why do photosynthetic sulfur bacteria use hydrogen sulfide?
Photosynthetic sulfur bacteria use hydrogen sulfide because it can serve as an electron donor in the process of photosynthesis. They can use the energy from oxidizing hydrogen sulfide to convert carbon dioxide into organic compounds, similar to how plants use sunlight. This process allows them to thrive in anaerobic environments where other energy sources may be limited.
In the nitrogen cycle bacteria combine nitrogen gas with hydrogen to form ammonia in a process called what?
You think probable to bacterial conversion.

You think probable to bacterial conversion.
Is hydrogen evolved in puterfaction?
Yes, hydrogen is evolved during putrefaction, which is the decomposition of organic matter by bacteria and fungi. This process produces various gases, including hydrogen, methane, and carbon dioxide, as byproducts of the breakdown of organic materials.
What body chemical kills bacteria without harming cells?
White blood cells produce hydrogen peroxide to kill bacteria without harming human cells. This process is known as oxidative burst, where the white blood cells create reactive oxygen species to target and destroy invading bacteria.
Which bacteria use inorganic substances instead of sunlight to make carbohydrates are?
Chemoautotrophic bacteria utilize inorganic substances, such as hydrogen sulfide, ammonia, or iron, instead of sunlight for the process of chemosynthesis to produce carbohydrates. Examples include sulfur-oxidizing bacteria and nitrifying bacteria.
How do some deep water bacteria in the ocean make food?
Some deep water bacteria in the ocean use a process called chemosynthesis to make food. These bacteria can convert chemicals, such as hydrogen sulfide or methane, into energy that they use to produce organic molecules. This process does not require sunlight and is essential for supporting life in deep ocean ecosystems.
What does bacteria that are adapted to live without oxygen combine carbon dioxide and hydrogen to produce?
Bacteria that are adapted to live without oxygen can combine carbon dioxide and hydrogen to produce methane gas through a process called methanogenesis. This type of bacteria are known as methanogens and they are typically found in anaerobic environments such as swamps, marshes, and the digestive tracts of animals.
What process is used by. Some Protista to actively ingest food particles?
Some protists use a process called phagocytosis to actively ingest food particles. During this process, the protist engulfs the food by extending its cell membrane around the particle, forming a food vacuole. Enzymes are then secreted into the vacuole to digest the food. This method allows protists to consume bacteria, organic matter, and other small particles from their environment.
