El Niños tend to result in drier conditions across Australia. Which of these is likely to occur in Australia during La Niña?
N76 [4]
Since Australia is located in the Pacific ocean, extremes of weather and climate happen throughout a season. El Niño is traditionally defined as a dry climate with reduced rainfall; in this happens to be more extreme in Australia because of its location. La Niña on the other hand is traditionally defined as a wet or cool climate with lots of rainfall; and this is indifferent as La Niña in Australia tend to be more extreme too.

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statemen
podryga [215]

Answer:

<u>Light microscope</u>:

  • use a beam of light to produce magnified images
  • can be used to examine living cells and tissues

<u>Scanning electron microscope</u>:

  • use a beam of electrons to produce magnified images
  • can be used to examine DNA
  • can be used to examine cells

<u>Transmission electron microscope</u>:

  • use a beam of electrons to produce magnified images
  • can be used to examine DNA
  • can be used to examine cells

Explanation:

Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.

Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:

  1. <u>Scanning electron microscope(SEM): </u>an electron beam passes over the specimen's surface and displaces electrons which are then focused on  a screen to form an image. Images appear in 3-D
  2. <u>Transmission electron microscope: </u>electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D
