Answer:

Biodiversity: Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. Biologists estimate that tropical rainforests contain about 50% of the world's terrestrial plant and animal species, yet they encompass only about 6% of the world's land area.

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

What is the probability of a pea plant with genotype rryy producing a gamete with genotype ry?
andrew-mc [135]

The probability of a pea plant with genotype rryy producing a gamete with genotype ry is 1.

<h3>What would be the probability of a pea plant producing genotype ry from the genotype rryy?</h3>

  • Probability is a measurement used in genetics to forecast the likelihood that a desired trait will be acquired by a child. The most easiest way to calculate the probabilities is to make a punnet square.
  • The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram. It bears Reginald C. Punnett's name, who developed the method in 1905. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
  • If we employ a punnet square for the genotype rryy producing a gamete with genotype ry the probability would be 1. You can refer the diagram for the understanding of the punnet square.
  • F1 genotype: rryy
  • F2 genotype: ry ry ry ry
  • Thus the probability would be 1.
