Answer:
A differential medium
Explanation:
Bacteria require nutrients for growth, and in order to culture (grow) them and study their characteristics, different types of media are used.
A selective media is used to grow a particular group of organism while suppressing another. So a selective media usually has an inhibitory agent, which will inhibit the growth of the undesired group. An antibiotic can be added to a medium to make it selective.
A general purpose medium as the name implies can be used to grow any group of bacteria. It has no inhibitory agent and indicator that differentiates between organisms. An example of general purpose media is nutrient agar
.
A non-synthetic media is made from natural ingredients.
A differential media differentiates between groups of organisms. Example of differential media is MacConkey agar and Mannitol Salt agar. On MacConkey agar, lactose fermenting bacteria turn pink while non-lactose fermenting bacteria are colorless.
On Mannitol Salt agar, mannitol fermenting bacteria turn yellow while non-mannitol fermenting bacteria are colorless. Mannitol Salt agar is also a selective medium. It has a high salt concentration which inhibits certain organisms.
The answer is <span>-Only the few bacteria that were immune to the antibiotic survived and reproduced, making all their offspring immune to it as well.
Bacteria (or any other organism) are not able to make changes to their DNA in order to protect themselves or to learn to remove the receptors on their cell surfaces. If they were able to produce toxins against the antibiotics, they would all survive.
These leave the second choice as the correct answer. This is the real situation, and is a good example of natural selection.</span>
Answer:
Well , I think the answer is B
This represents a closed system,and one benifit is that the risk of passing disease between other species is lower than in open system
But still I prefer you to check it out in your book
I was able to find 10 endangered species. And they are:
Kings Gold its a plant.
Delta Smelt its a fish
Amargosa vole it is a critter either a rat or a mouse.
Tricolored blackbird it is a type of a song bird.
Buena Vista Lake ornate shrew it is a type of mouse or rat
Desert Slender Salamande it is a reptile. type of lizard
Lange's metalmark butterfly
Sacramento river winter-run Chinook salmon it is a type of fish
California condor it is a type of bird
Gray wolf
Hope this helped
