C  Bacteria evolve and become resistant to antibiotics.

Explanation:

Bacteria are small micro-organisms found in nature. They are useful to all life and the same time can be harmful.

Bacteria can evolve and become resistant to antibiotics thereby causing serious health problems.

  • Bacteria in living cells can develop resistant strains which prevents antibiotics from acting on them.
  • With the passage of time, the bacteria can change their structure into that of a more resistant strain.
  • This can prevent antibiotics from acting on them and by so inflict serious damage to life.

What is the molarity of a solution which has a volume of 3 litres and contains 5.1 moles of Br2?
katrin [286]

Answer:

The molarity of the solution is 1.7 \frac{moles}{liter}.

Explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

Molarity=\frac{moles of solute}{volume of the solute}

Molarity is expressed in units \frac{moles}{liter}.

In this case, you know:

  • moles of solute= 5.1
  • volume= 3 L

Replacing:

Molarity=\frac{5.1 moles}{3 L}

Solving:

Molarity= 1.7 \frac{moles}{liter}

<u><em>The molarity of the solution is 1.7 </em></u>\frac{moles}{liter}<u><em>.</em></u>

According to Darwin’s theory if evolution, which organism are Best able to survive in nature
Arlecino [84]

Answer:

Organism best adapted to the environment are able to survive in nature!

Explanation:

Suppose there was a green forest but after a volcano eruption all the green colored vegetation is lost and the area turns black . Now some organisms did survive...you have a black rat, and a white rat. You also have vultures flying in sky looking for prey. Overtime, the organism best adapted to environment can reproduce more and survive in nature. In our example, the black rats are the best adapted because their color matches with the environment so the eagles or vultures would have a hard time spotting them, whereas, a white rat in a black environment can be easily spotted so it has less adaptation to the nature.
