What are similarities and differences between compound light microscopes and electron microscopes?

Answers

The similarities between compound light microscopes and electron microscopes are as follows:

  • Both types of microscopes utilize radiation to construct a larger and more detailed image of objects.
  • Both types of instruments are used for the visualization of small objects like biological specimens, crystal structures, etc.

What is an Electron microscope?

An electron microscope may be defined as a technical instrument that is significantly utilized in order to obtain a high-resolution image of biological and non-biological specimens with the help of a beam of accelerated electrons.

The differences between compound light microscopes and electron microscopes are as follows:

  • A Light microscope uses light radiation to form an enlarged image, while an electron microscope uses a beam of accelerated electrons for the same.
  • An Electron microscope uses a much shorter wavelength as compared to visible light and thus forms a high-resolution image than that of a light microscope.

Therefore, the similarities and differences between light and electron microscopes are distinctly explained.

1. A flexible, supporting structure found only in chordates is the A. nerve net
B. notochord
C. pharyngeal slits
D. dorsal fin.

2. Ancient chordates are thought to be most closely related to which of the following species?
A. spiders
B. earthworms
C. octopi
D. sea stars

Answers

A flexible, supporting structure found only in chordates is the notochord. The correct option among all the options that are given in the question is the second option or option "B".

Ancient chordates are thought to be most closely related to sea stars. The correct option among all the options that are given in the question is the last option or option "D".

The notochord is a flexible, supporting structure found only in chordates. Ancient chordates are most closely related to octopi.

The correct answer for the first question is B. notochord. The notochord is a flexible, supporting structure found only in chordates.

It provides support to the body and serves as a precursor to the vertebral column in vertebrates. Examples of chordates include fish, birds, and mammals.

The correct answer for the second question is C. octopi. Ancient chordates are thought to be most closely related to cephalopods like octopi.

Both groups share certain characteristics in their body structure and development.

Answer:

they will all be brown horses but only two will have both dominant alleles, the other two will each have one recessive

A textile company has started a program to recycle textiles so they are not added to a nearby landfill as part of the waste stream. The company collects old T-shirts, sorts them by color, breaksdown the fibers, and respins the fibers into yarn which is used to make new shirts. The recycling process is different from traditional manufacturing because it does not use dyes and it reduces
the amount of water used in the manufacturing process to make new shirts
(a) One drawback of traditional textile manufacturing is that it can release dyes into nearby rivers
( Identify an ecosystem service provided by rivers.
(1) Assuming the dyes are dark in color, describe how photosynthetic algae living in the water would be affected by the release of dyes into rivers.
(18) Textile dyes often contain heavy metals such as lead, chromium, and cadmium Describe how heavy metals in nearby rivers could affect predators at the top of the food chain

Answers

Answer:

i. An ecosystem service provided by river include water for irrigation and drinking.

ii. Photosynthetic algae living in the water would be affected by the release of dyes into the rivers because dyes can block sunlight and prevent photosynthesis. Algae is the base of most river ecosystem so without direct sunlight due to the dye in the water, the entire ecosystem would be in jeopardy.

iii. Heavy metals in nearby rivers could affect predators at the top of the food chain because the metals consumed by primary and secondary consumers would be digested by the predators on top. The toxins from the heavy metal build up the higher in the food chain.

Explanation:

The human body uses specialized biomolecules to speed up chemical reactions. These are called enzymes. Without enzymes, the reaction in the body would happen too slowly to keep you alive. Which biomolecule do enzymes belong to?
A. Proteins
B. Lipids
C. Nucleic acids
D. Carbohydrates ​

Answers

Final answer:

Enzymes are biomolecules that belong to proteins. They are vital for speeding up chemical reactions in the human body to ensure healthy living.

Explanation:

Enzymes are specialized biomolecules that play a fundamental role in the human body, primarily by speeding up chemical reactions critical for life. These biomolecules belong to the category of Proteins. This is because enzymes are composed of sequences of amino acids, which are the building blocks of proteins.

Unlike lipids, nucleic acids, and carbohydrates, proteins possess the unique ability to function as biological catalysts, reducing the amount of energy required for a reaction and thereby accelerating its rate.
