Can inhalation of natural gas cause bronchitis?
Inhalation of natural gas can lead to respiratory symptoms such as coughing and shortness of breath, but it is unlikely to directly cause bronchitis. However, exposure to natural gas can irritate the respiratory tract and worsen existing conditions like bronchitis. It is important to seek medical advice if you have concerns about respiratory symptoms related to natural gas exposure.
Are Antibiotic resistance evolved through the process of natural selection acting upon random mutation?
Yes, antibiotic resistance typically arises through a combination of random mutations in bacteria's genetic material and natural selection favoring those bacteria that have mutations conferring resistance to antibiotics. Over time, these resistant bacteria survive and multiply, leading to the emergence of antibiotic-resistant strains.
An antibiotic is effective in killing 95 percent of a population of bacteria that reproduce by the process shown below which statement best describes future generations of these bacteria?
Future generations of these bacteria are likely to have a higher proportion of individuals that are resistant to the antibiotic due to natural selection. Over time, the resistant bacteria will survive and reproduce, potentially leading to the evolution of a population that is largely resistant to the antibiotic.
What is source of wax?
Wax is a natural substance secreted by bees to build their honeycombs. It can also be derived from plants, such as carnauba wax from the leaves of the carnauba palm, or produced synthetically from petroleum.
Skin cells secrete a natural antibiotic called what?
They're called Langerhans cell. On infection of an area of skin, the local Langerhans' cells will take up and process microbial antigens to become fully-functional antigen-presenting cells. http://en.wikipedia.org/wiki/Langerhans_cell
Is turmeric a natural antibiotic?
yes
Resinous substance secreted by an insect?
Resinous substance secreted by an insect is called "lac." Lac is a sticky, water-resistant material used for making shellac, a type of varnish, or for producing natural red dye.
Explain how natural selection can give rive to a population of antibiotic resistant bacteria?
Consider the following scenario: An antibiotic is applied to a petri dish of bacteria. The antibiotic will kill of most of the bacteria, but some will remain that are immune to the antibiotic. Therefore, only the immune bacteria will reproduce. Soon, the whole petri dish will be full of bacteria that is immune to the antibiotic. Nature "selects" the immune bacteria for survival.
Why the human respiratory system can be thought as a natural pneumatic system?
human respiratory uses air pressure like pneumatic system does
What role does antibiotic have in yeast infections of the urinary tract?
Antibiotic treatment for bacterial infections can produce yeast infections. Yeast infections due to antibiotic treatment are caused by the destruction of good and bad bacteria, and disrupts the vaginal flora.
How does tetracycline act as an agent for natural selction?
as the bacteria it was exposed to, eventually one strain mutated and this lead to a resistance to the antibiotic, and therefore the bacteria with the mutation was able to reproduce, where as the other bacteria would have been killed off by the antibiotic. Thus natural selection is achieved, yipee!(not for us)
Red sweat hippos?
The red sweat is a natural antibiotic sunscreen to protect them from the heat and sun.
What is the Russian penicillin?
it's garlic, it contains alicin a powerfull natural antibiotic which does not atack healthy bacteria in your gut.
Is ampicillin natural or synthetic?
Ampicillin is a semi-synthetic antibiotic, meaning that it is derived from a natural source (penicillin) but has been chemically modified to enhance its effectiveness.
What is the example of a microevolution?
An example of microevolution is the development of antibiotic resistance in bacteria due to natural selection. Over time, bacteria that are resistant to antibiotics survive and reproduce, leading to a population of bacteria that is predominantly resistant to that antibiotic.
How do antibiotic resistant bacteria come about?
This term is misleading. The antibiotic "selects" bacteria that are not affected by it. If a person will grow bacteria on a petri dish and add an antibiotic to it, some bacteria may live and grow. This is actually a form of natural selection. The ones that will grow are resistance to the antibiotic. They have some way of not being affected. If a person takes a colony from the plate that has this resistance and grows it on another plate and add the antibiotic, all on the plate will be resistant.
Which form of respiratory therapy is used temporarily to replace a patients natural breathing?
ventilator
