What effect might antibacterial soaps have on the evolution of bacteria?
Provide a selective environment where those with resistance survive and replicate and those without die off. Gives rise to resistant bacteria.
How are bacteria essential for human life?
Bacteria is crucial to life on earth. The reason bacteria is crucial is because of their role in the ecosystems they live in. Some bacteria break down dead organic debris to decompose waste in the ecosystem. Other bacteria live inside of organisms to benefit the health of the living organism by eliminating harmful substances in the body.
What name is given to the chemicals that are added to plants in order to provide them with essential chemical elements?
your nan
What is a green pigment that absorbs light to provide energy for photosynthesis it is present in most plant and algae cells and some bacteria?
Oh Chlorophyll!
In a Science Experiment What does the word Control mean?
i love glenn in 5 grade hahahahahahah i love him i want to merry him ahahahahhahhahahahahahhahahhau r stupid control is a variable that doesnt deviate from its origin...okay in simpler terms ill provide an example. just say that you wanted to see if certain chemicals would make a plant grow in a different way or outrightly kill it. you would assemble three test tubes with a certain germinating plant. the first would be a controled state meaning you would just add water. second and third would be water as well as individual chemicals that you wanted to see what happened.
Describe two ways bacteria provide nutrients to humans?
Bacteria in our gut help break down indigestible fibers from food to produce short-chain fatty acids that provide energy to our cells. Certain bacteria also synthesize vitamins, such as vitamin K and certain B vitamins, that our bodies are unable to produce on their own.
Some bacteria produced chemicals that provide food with a certain taste name two such foods?
Two foods that are enhanced by chemicals produced by bacteria are yogurt and sauerkraut. In yogurt, lactic acid bacteria ferment lactose, producing lactic acid that gives it a tangy flavor. Similarly, in sauerkraut, fermentation by specific bacteria creates acids that contribute to its distinctive sour taste.
Why do certain bacteria such as tetanus and botulism coat themselves with wax-like outer shells?
Certain bacteria, like those causing tetanus and botulism, produce wax-like outer shells, or spores, as a survival mechanism. These spores provide protection against harsh environmental conditions, such as extreme temperatures, desiccation, and exposure to chemicals. By forming these resilient structures, the bacteria can remain dormant for long periods until they encounter favorable conditions for growth and reproduction. This adaptation enhances their survival and ability to cause disease when conditions permit.
What removes chemicals from vegetables?
Washing vegetables with water can help remove some chemicals, pesticides, and bacteria. Using a fruit and vegetable wash or a mixture of water and vinegar may provide added benefits in removing residue, though some chemicals may still be present as they can penetrate the skin of the produce. Organic produce generally has lower levels of chemical residues.
What happens to chemicals that come from the hydrothermal vents?
Chemicals from hydrothermal vents are released into the water and can provide energy for unique ecosystems through a process called chemosynthesis. Some chemicals are used by specialized bacteria to produce organic material, supporting a variety of organisms in the vent community. Others disperse into the deep ocean and may have far-reaching effects on marine life.
The relationship between Pompeii worms and thermophile bacteria?
Pompeii worms have a symbiotic relationship with thermophile bacteria that live in their tissues. The bacteria provide nutrients to the worms through chemosynthesis, converting chemicals from hydrothermal vents into usable energy. In return, the worms provide a habitat and protection for the bacteria.
How might the physical differences between gram positive and gram negative bacterica contribute to differences in chemical resistances?
Gram positive bacteria do not contain a protein sheath over their peptidoglycan membrane layer. Because of this, a gram negative bacteria's membrane (which contains a protein coating over the peptidoglycan) is more resistant to being penetrated by chemicals.
What elements are used to make orange firework?
The color orange in fireworks can be produced by using a combination of pyrotechnic chemicals such as calcium salts, including calcium chloride or calcium sulfates, mixed with a fuel such as charcoal or sulfur. These chemicals provide the orange color when they are burned and produce the characteristic orange flames in fireworks displays.
What ingredients in EMB agar contain carbon and nitrogen?
The peptones in EMB agar provide nitrogen for bacterial growth, while the lactose is a source of carbon. These ingredients support the growth of certain coliform bacteria, which ferment lactose to produce characteristic color changes on the agar.
What are autotropes?
Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis. They are able to convert inorganic compounds into organic compounds to provide the energy needed for growth and survival. Examples of autotrophs include plants, algae, and certain bacteria.
Plasmids are naturally found in some?
bacteria. They are small circular DNA molecules that can replicate independently from the bacterial chromosome. Plasmids often carry genes that provide bacteria with various advantages, such as antibiotic resistance or the ability to metabolize certain nutrients.
What do vent tubeworms and chemosynthetic bacteria get from there close relationship?
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.
