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

Answers

Answer 1

Answer:

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.

In 1831, Charles Darwin visited the Galapagos Islands. While observing the giant land tortoises that lived on these islands, Darwin noted that the shape of the tortoise shell varied depending on which island the tortoise lived. Tortoises on one island had round shells, for example, whereas tortoises on a neighboring island had more flattened, saddle-shaped shells. Which statement BEST summarizes Darwin's explanation for these differences?A) Random mutations caused the shape of the shells to fluctuate periodically.
B) The shape of the tortoise shell varied because the predators on the islands were different.
C) The particular shape of the shell was best suited for the island on which the tortoise was living.
D) Tortoises who used their shells in special ways caused the shells to become larger, rounder, or flatter.

Answers

B) The shape of the tortoise shell varied because the predators on the islands were different.

Natural Selection is a process where “survival of the fittest” is based from. Because the environment cannot support all organisms borne, those organisms must compete with each other for food, shelter and protection. Organisms may die due to accidents but majority of the organisms die due to their inability to survive stiff competition.

Darwin’s theory of evolution
1)      Variation exists among individuals within species.
2)      Organisms produce more offspring than the environment can support
3)      Competition exists among individuals.
4)      The organisms whose variations best fit them to the environment are the ones who most likely to survive, reproduce, and pass those desirable variations on to the next generation.

Multiple alleles _____. a. can interact and influence a trait such as eye color, b. cannot interact to influence traitsc. that interact are always sex linked
d.are made of RNA

Answers

Answer:

The correct answer would be option A. It can interact and influence a trait such as eye color.

Explanation:

Three or more alternative alleles of a gene that can occupy the same locus known as multiple allele condition. However, only two of the alleles can be present.

The ABO blood group system and human eye color are examples of the multiple allele condition.

Eye color is determined by multiple genes. OCA2 and HERC2 Both are located on human chromosome 15. A common polymorphism in the HERC2 gene is accountable for the blue eye. A person with homozygous TT predicts likely to have brown eyes, while a person with 2 copies of C allele at HERC2 rs1293832 will have blue eyes.

Thus, the correct answer would be option A.

What is a possible cost of habitat destruction?Non-sustainable energy
Fewer landfills
Less biodiversity
Fossil fuel decreases

Answers

A possible consequence of habitat destruction is less biodiversity. The variety of life forms that reside in a habitat are highly dependent upon that particular environment. Often, when a habitat is destroyed the life within is destroyed as well, or at the vary least has difficulty finding a new habitat and may have to adapt themselves in ways that make them similar to the life that already exists in the new habitat, leading to less biodiversity.

Habitat destruction leads to loss of biodiversity because many organism are killed in the process of habitat destruction.

What is a habitat?

A habitat is the place where an organism lives. It is the abode of an organism. One of the serious environmental disasters in recent time is habitat destruction.

A student is drawing a model of the carbon cycle. Which caption should he include to explain how herbivores contribute to the carbon cycle from the food they eat?

Answers

Answer:

Cellular respiration

Explanation:

Herbivores are organisms that feed on plant materials solely. They are usually animals like sheep, cattle, goats with four stomach compartments. They are part of the global carbon cycle which shows how carbon is circulated in nature.

Plant matter is broken down by herbivores through a series of metabolic steps.
The final product is a glucose laden material which is the raw material needed for cellular respiration.
When oxygen combines with the glucose, energy is liberated, and carbon dioxide, a waste product is released into the atmosphere.
This way, carbon is cycled in the ecosystem.

Answer:

Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.

A tree grows about one-foot each year. you carve your initials into the trunk of a tree that is 15 feet tall. your initials are four feet above the ground today. How far above the ground will they be in 10 years? why?

Answers

The initials will still be 4 feet above the ground.

Trees do not grow from the bottom up. At the branch tips there is meristem tissue, so called the apical meristem. Trees grow in height from these apical meristems, so trees grow from the top and the initials on the bottom of the tree will stay at the same height above the ground.
