Bacterial resistance arises through the simple process of natural selection. Bacteria divide rapidly, but DNA replication is imperfect. In the presence of antibiotics, while most bacteria are killed, a small number of resistant mutants may survive and take over.

Would the surface temperature of white dwarf stars be higher or lower than red supergiants?
Liula [17]
The surface temperature of white dwarf stars is higher than that of red super giants. White dwarf stars are extremely hot when they form, and they start cooling off as time goes by. Red supergiants, on the other hand, are enormous dying stars, and they are quite cool. So, having this in mind, white dwarves are hotter than red supergiants. Hope I helped! :) If it’s wrong then I’m sorry!

If an organism has a high biological fitness in one environment ,does that mean that it would also have high biological fitness
dsp73

The answer is NO. This is because different environments require different adaptations. A desirable trait in one environment may be inconsequential or detrimental in another environment. This is the reason also why evolution is continuous as natural selection acts on traits of a population to ensure desirable traits are retained with changes in the environment in a dynamic world.
