1. Simple optical microscope. One lens.
Disadvantage: Only Van Leeuwenhoek made them, and he's dead.
Advantage: Worked pretty well. With them, Van Leeuwenhoek discovered protozoa and bacteria.

2. Compound optical microscope. Has both an ocular and objective lens.
Disadvantage: limited resolution. Can resolve bacteria, but not smaller things like viruses.
Advantage: can be used with live specimens (using phase contrast or polarized or other special illumination).

3. Binocular dissecting microscope (optic). Has a pair of ocular and objective lenses, and supposedly presents a "3D" view of the specimen to the viewer (I was never able to see in 3D using these darn things).
Disadvantage: Limited magnification
Advantage: Can be used to perform surgery on small but not microscopic specimens, such as fruit flies. Is used in "microsurgery" in hospitals too.

Hope this helps buddy!

Answer:

The three types of specimens a dissecting microscope are as follows:

  1. Optical Microscopes.
  2. Electron Microscopes.
  3. Scanning Probe Microscopes.
  • Optical microscopes are the oldest and the simplest microscope it uses a single convex lens to enlarges the image placed under its focus.
  • Electron Microscope is used by scientists to study cell, this microscope fire beams of electrons on the subject which is held in the vacuum-sealed tubes.
  • Scanning probe microscopy is a powerful microscope, it can detect matters smaller than the nano-meter however its images have no color because it uses probe measure things other than visible light.

<h3><u>Answer;</u></h3>

absorbed by Earth’s core

When energy from the sun reaches Earth, it is not <em><u>absorbed by Earth's core.</u></em>

<h3><u>Explanation;</u></h3>
  • <em><u>The energy from the sun reaches the earth, such that 23 percent of the incoming solar radiation is absorbed by the atmosphere by water vapor, dust and ozone. </u></em>
  • <em><u>48 percent of the solar energy is absorbed by the earth's surface, this translates to 71 percent of the energy which is absorbed by the systems of the Earth.</u></em>
  • <em><u>The remaining 29 percent is reflected back to space by clouds, atmospheric particles etc. </u></em>

Explain why flask #2 (yeast with glucose) produced more CO2 than flask #5 (yeast with flour). AND how did you know it produced m
Agata [3.3K]

Answer: Glucose

Explanation:

The carbon dioxide produced in the experiment can be directly related to the energy generated after the fermentation process. The carbon dioxide is the byproduct of the chemical reactions in the ethanolic fermentation. Glucose substrate will yield the highest energy along with the highest producer of the carbon dioxide after the fermentation process conducted by yeast as compared to the fermentation process that was conducted by yeast with flour. The flour will offer a source of carbohydrates including starch and sugars. The yeast will find out sugar in the flour and ferment it. Glucose is readily available sugar for the action of yeast so more production of carbon dioxide is expected from glucose substrate.

What are the differences between flow of matter and energy in an ecosystem? Why?
My name is Ann [436]
The key difference between energy flow and matter cycling is that energy flow shows the energy transmission from one trophic level to next trophic level in food chains while matter cycling shows the flow or cycling of elements through the living and nonliving parts of ecosystems
