1. What is the total magnification of an object if the ocular lens magnification is 20x and the objective lens magnification is

V125BC [204]

1. Answer: 900x

A typical microscope has two lens: ocular lens which located near the eye, and objective lens which located near the object. The image will undergo magnification of both lens. The total magnification of the object would be the product of both lens multiplication, not the sum. The multiplication will be: 20x * 45x= 900x

total mag= ocular * object

total mag= 20x * 45x

total mag= 900x

2. Answer: 100x

The total magnification of the object would be the product of both lens multiplication. If the total magnification 1000x, that mean it was the product of ocular lens and objective lens. If ocular lens magnification is 10x, objective lens magnification would be:

total mag= ocular * object

1000x= 10x*object

object=1000x/ 10x=

object=100x

3. Answer: 0.2 mm

The area of the microscope that can be viewed by the eye should be the same. But since the magnification is different, the actual area that it represent will be different. Microscope with bigger magnification will have smaller diameter of the field of view(DFV). Remember that micrometer(μm) is 1/1000 of millimeter(mm). The DFV would be:500 μm/ ( 1000x/400x)= 200μm= 0.2 mm

4. Answer: 750μm

This question is similar to number 3 question. Remember that 1 millimeter(mm) equal to 1000 micrometer(μm) .

The DFV of a 10x objective lens is 3 mm. Then the DFV of 40x lens would be:

DFV2= DFV1/ (mag1/mag2)

DFV2= 3mm/ ( 40x/10x)= 0.75 mm= 750μm

5. Answer: 125μm x 37.5μm

The lens DFV of microscope from question 4 is 750μm, so the width and length of the area would be 750μm.

If 6 organisms could fit across the DFV if they were laid end-to-end, the length would be: 750μm/ 6 organism= 125μm

If 20 organism could fit is stacked side by-side, then the width would be: 750μm/ 20 organism= 37.5μm

6. Answer: 6mm

This question is similar to number 3 and number 4 question. Remember that 1 millimeter(mm) equal to 1000 micrometer(μm).

The DFV of a 100x objective lens is 1.5 mm. Then the DFV of 25x lens would be:

DFV2= DFV1/ (mag1/mag2)

DFV2= 1.5mm/ (100x/25x)= 6 mm

7.Using the 100x objective lens from question 6, you estimate 12 organisms could fit across the DFV if they were laid end-to-end and 30 could fit is stacked side-by-side. What is the length and width of this organism (in microns)?

Answer: 0.5mm x 0.2mm or 500μm x 200μm

The lens DFV of microscope from question 6 is 6 mm, so the width and length of the area would be 6 mm.

If 12 organisms could fit across the DFV if they were laid end-to-end, the length would be: 6mm/ 12 organism=0.5mm

If 30 organism could fit is stacked side by-side, then the width would be: 6mm/ 30 organism= 0.2mm

How do sulfur and phosphorus move from the biotic to the abiotic pools during their cycles? A) Primary consumers eat producers.

worty [1.4K]

Answer:D) Decomposers break down the remains of producers and consumers

Explanation:A biotic pool is a tidal pool with diverse and changing habitats of living factors. We can say they are important mini ecosystems within the larger ecosystem.

The abiotic pool involves the elemental phases of nature,the non living parts of the ecosystem. Decomposition (break down) of elements/organic compounds is the characteristic bridge between both pools into what is known as nutrients.

This tell us that the ultimate dead part of producers and consumers are used up in this process.

Some of the nutrients released in the biogeochemical cyclic process includes sulfur and phosphorus and they move through the ecosystem.

Note: The biogeochemical cycle is a pathway of movement for chemical elements.

The chemical elements in nature moves through both biotic and abiotic components via abiotic and biotic interaction in the ecosystem

Few abiotic factors includes rocks, air, water, and chemicals while biotic factors includes living organisms activities.

All living and non living elements of nature play vital roles in the great biogeochemical cycle.

What is one way a plain can form?

ryzh [129]

Answer:

A. Erosion from wind, water, or ice removes crustal material.

Explanation:

Plain formation can occur in many different ways some plates some planes can form as wind, water and ice erode wear away or remove dirt and rocks on higher land.

Wind picks up and carries along small particles which can be abrasive against surfaces, slowly wearing them away to form more particles. The water and ice transport the fragments of rock and dirt as sediment down hillsides, where it is eventually deposited. This occurs until several layers of sediment are accumulated. Plains can also form at the bases of mountains where water carries a flow of sentiments downhill to flat areas where it further spreads out to deposit the sediment in a fan shape -this is called an alluvial plain.
