Answer: The correct answer is -

A: beneficial.

Mutation can be described as permanent change in the genetic material (DNA, deoxyribonucleic acid) of living organisms.

In certain genes of bacteria, mutation allows them to become resistant against powerful antibiotics.

Due to this, bacteria are no more sensitive to the action of antibiotics that is they can not be killed by the action of antibiotics.

Thus, such mutation is beneficial to the bacteria as it is increasing the rate of survival of bacteria.

Therefore, option A) is the right answer.

  • This was in the Miocene epoch which was about 6 million years ago.
  • Compared to the age of the earth, this time lapse is very small and not up to 1%.

Michelle drew a simple diagram to show how a hurricane forms. Which location on the diagram indicates a low-pressure area?
inysia [295]

Answer:

"Location 4" indicates a low-pressure area

Explanation:

A low-pressure area is defined as the region in which the pressure in the atmosphere is comparatively lesser than nearby surrounding areas. This region is a depression that is comprised of more winds, warmer air, and lifting of air mass takes place.

In a low-pressure zone, the warm air becomes less dense, due to higher temperature, as a result of which it rises up into the atmosphere. As it rises up into the atmosphere, it eventually cools and condensation starts taking place. After a definite period of time, rainfall occurs.

Thus, in the given image, location 4 shows the low pressure area.
