What else can I help you with?
Would you expect to find thermoacidophilic bacteria and enteric bacteria living in the same environment?
It is unlikely to find thermoacidophilic bacteria and enteric bacteria in the same environment, as thermoacidophiles typically thrive in high-temperature, acidic conditions (such as hot springs), while enteric bacteria typically inhabit the gastrointestinal tracts of animals and humans. Their optimal growth conditions and habitats differ significantly.
What is the first step in identifying bacteria?
There are many ways to identify an unknown bacteria. The method to identify depends on tools available and setting. A medical setting has different identification process than an educational setting. Both places would usually begin with a gram stain. A gram positive bacteria would appear purple under a microscope, whereas gram negative would appear orange. Another way to identify bacteria would be to choose different agar plates to grow the bacteria. The presence of bacterial growth on different media helps to identify the unknown bacteria.
What bacteria do humans carry?
Humans carry a wide variety of bacterial species on their skin, in their mouth, gut, and other body sites. Some common bacteria found on or in humans include Staphylococcus aureus, Escherichia coli, and Bacteroides fragilis. These bacteria can have both beneficial and harmful effects on human health.
What is the characteristic of bacteria?
Bacteria are single-celled microorganisms that lack a nucleus and organelles. They have a cell wall and reproduce through binary fission. Bacteria can be beneficial or harmful to humans and other organisms.
What type of immune response would occur if bacteria invaded your lymph?
Since the bacteria has already invaded your body, the second stage of defense is required. The lymphocytes will engulf the bacteria and digest it using lysosomes. When the bacteria is gone, fragments of the bacteria are left behind by the lymphocyte to allow some T-cells to identify the bacteria's antigen.
What problems would bacteria have if humans didn't exist?
None.
What type of bacteria would you find in humans?

Which would evolve faster humans or bacteria?
Bacteria would evolve faster than humans due to their shorter generation times and larger population sizes, allowing for quicker adaptation to environmental changes and mutations to occur. Humans have longer generation times and smaller population sizes, slowing down the rate of evolution.

Why humans are considered to be a very successful species?
They are not, bacteria is the most important species - without them humans would not last more than a few hours.

Natural selection example?
A great example would be Antibiotics and Bacteria. When humans create an antibiotic, it wipes out a lot of the bacteria in your body. The ones that that don't get affected by it probably have a resistance to the antibiotic. As those bacteria multiply and grow, the others die out due to the antibioitic. Soon the anti-biotic resistant bacteria will take over the human body, and the humans would have to find another antibiotic to counter the new bacteria. The cycle goes on and on......
Why would humans be interested in introducing mutations into bacteria?
Introducing mutations into the bacteria is called "engineering" the bacteria. it allows bacteria to be developed that can be put to work for useful purposes (devouring oil spill gunk, as one example), and there are hundreds of other uses for engineered bacteria, too.

When is zoonosis hard to trace?
Sometimes the infection is fairly common among both humans and animals, and it is impossible to tell. Snakes may carry the bacteria Escherichia coli and Proteus vulgaris, but since these bacteria are common in humans, it would be difficult to trace.
