I'm pretty sure the answer is true. Hope this helps!
Answer:
Novobiocin target DNA GYRASE of gram positive bacteria.
Explanation:
Novobiocin is a bacteriostatic(slow down bacteria growth) or bactericidal i.e it kills bacteria , narrow spectrum antibiotics that target DNA GYRASE of gram positive bacteria. It acts by inhibiting the bacteria DNA gyrase hydrolysis thereby by interfering with the metabolic activities of bacteria. It is also a weak catalytic inhibitor of mammalian. Novobiocin inhibit DNA gyrase and topoIV by binding to the ATP pocket of GyrB and ParE, respectively.The Streptomyces strain that produces Novobiocin and it is more effective on gram positive bacteria that gram negative bacteria because gram negative bacteria are resistant to it.
Answer:
predation
Explanation:
If the first coat color is black for example, the mice will be able to hide away in a dark area or corner, they will also be able to move around at night almost undetected. Changes in environment, such as development and introduction of street lighting may cause these mice to be easily seen by predators. These mice will quickly be eaten by predators now that they are accessible. On the other hand mice that have a different color such as white or grey will be able to blend in better with the new surroundings. These mice will pass along this trait to their progeny and the new coat color will proliferate.
Antibiotics only kill bacteria. Viruses aren't even alive to begin with.
Answer:
As convection currents reach the mantel, the heat causes a collision between the continental plate and the oceanic plate under water. The convection current continues to push the heated magma past the mantel level, reaching the crust of the Earth's surface and producing a lava spout.
