why it is important to know the speed of earthquake waves, the strength of the waves and how do we determine the location of the epicenter of an earthquake. ?

Answers

Answer 1
Answer:

Answer: As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

Frank Lloyd Wright’s Fallingwater house is best described as an example _______. a. of a private residence becoming publicly important b. of modern houses and architecture c. of a private residence d. of waterfalls and natural scenery

Answers

Answer;

A. of a private residence becoming publicly important

Frank Lloyd Wright's Fallingwater house is best described as an example of a private residence becoming publicly important.

Explanation;

Frank Lloyd Wright first became known for his Prairie Style of architecture which incorporated low pitched roofs, overhanging eaves, a central chimney, and open floor plans which, he believed was the antidote to the confined, closed-in architecture of the Victorian era.

Falling water is a house designed by architect Frank Lloyd Wright in 1935 in rural southwestern Pennsylvania. The house was designated a National Historic Landmark in 1966.

Answer:

A. of a private residence becoming publicly important

In a food web, each ____________ depends on the trophic level below it for energyA) Consumer
B) Decomposer
C) Detritivore
D) Producer

Answers

Answer:

The correct answer would be A) consumers.

Consumers are the organisms which depend on other organisms for their energy needs.

In a food chain, the consumer consumes other organisms present on lower trophic level.

For example, cow, deer, et cetera (herbivore) are the primary consumers which consume autotrophs or green plants which are present on lowest trophic level.

Similarly, lion, tiger, et cetera are the highest consumers which feed on organisms present on lower trophic levels such as cow, deer, giraffe et cetera.

A) Consumer

The consumer relies on the 
trophic level below it for energy to survive.

1. An advantage of light microscopes compared to electron microscopes is that light microscopes A)allow you to view living cells, while electron microscopes do not. B)allow you to view the surface of cells in greater detail than electron microscopes. C)have a higher magnification capability because they use natural light. D)have a greater resolution available because they use white light. 2. To study the details of protein molecules on the surface of a cell, a biologist would likely use a A) compound light microscope. B) dissecting microscope. C) scanning electron microscope. D) transmission electron microscope. 3. What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x? (2 points) 40x 50x 400x 500x

Answers

Answer:

1. The correct answer would be  A) allow you to view living cells, while electron microscopes do not.  

There are many advantages of light microscope over electron microscope such as:

  • It is easy to use as compared to the electron microscope.
  • It enables us to view both alive as well as dead specimen whereas electron microscope can be used to view dead specimen only.
  • Light microscopes are much cheaper and have much lower maintenance cost as compared to the electron microscope.

2. The correct answer would be C) scanning electron microscope

Scanning electron microscope or SEM is a type of electron microscope which is used to observe surface topography and composition of the specimen. It can achieve resolution of up to 1 nanometer.

3. The correct answer would be 400x

The total magnification of the microscope can be calculated by multiplying the powers of the objective lens and that of the eye lens.

Thus, the magnification of the specimen would be 40*10 = 400x.

1. The correct answer is A) allow you to view living cells, while electron microscopes do not. Light microscopes use visible light to illuminate specimens, which is less damaging to living cells compared to the electron beams used in electron microscopes.

The electron microscope

2. The correct answer is C) scanning electron microscope. Scanning electron microscopes (SEMs) are commonly used to study the details of protein molecules on the surface of cells. SEMs provide high-resolution images of the surface topography by scanning the specimen with a focused beam of electrons.

3. To calculate the total magnification of a compound light microscope, you multiply the magnification of the objective lens by the magnification of the ocular lens. In this case, the objective power is 40x, and the ocular lens power is 10x. Therefore, the magnification of the specimen viewed with this compound light microscope would be 40x * 10x = 400x. So, the correct answer is C) 400x.
