4. Estimate the size of the outlined (yellow) onion cell under high power (40x). Use the dFOV values calculated from question no. 3. 10 points
The following formula is useful to determine the size of the cell ⇒ Size of the object = FOV / Fit number = dFOV / Fit number. If you have this data, you can estimate the size of the onion cell. According to the values we used, the estimated size of this onion cell is 112 μm.
-----------------------------------------------
Cells are too small to measure their sizes, so to know their actual size, we can make mathematical estimations to know their sizes, or we can use software programs. In this case, we are estimating their size using the following formula,
Size of the object = FOV / Fit number = dFOV / Fit number
Size of the object = size of the cellFOV = eyepiece (mm)/objective magnification Fit number = The number of times the object -cell- fits in the field of viewTo answer this question, we will replace the terms in the given formula.
→ First, we will get the FOV value. From references, we can assume that
under 4X ⇒ FOV = 4.5 mmunder 10X ⇒ FOV = 1.8 mmunder 40X ⇒ FOV = 0.45 mmYou can also calculate the FOV by using a millimeter paper or rule.
Note: We will use these values to replace terms in the formula, but you can use the dFOV value calculated in question no. 3.
→ Second, we will count the number of cells that fit the field. We can see about four cells across the field of view.
→ Finally, we will replace the terms in the formula.
Size of the object = FOV / Fit number
Size of the object = 0.45 mm / 4
Size of the object = 0.112 mm
Since we generally use μm when referring to cell sizes, we need to multiply 0.112 x 1000 to get the size of the cell expressed in μm.
Size of the cell (μm) = 0.112 mm x 1000 = 112 μm

Land reform and land colonization can have negative effects on the environment and have controversial social ramifications.
Why are these strategies used, even when they have negative effects?
A. They are the cheapest way to increase productivity.
B. Their purpose is to increase the global food supply and reduce malnourishment.
C. If these strategies are not used, pest management will become a severe issue that will destroy many crops.
OD.Chey are needed to implement genetic modification of crops.
Answer:B. Their purpose is to increase the global food supply and reduce malnourishment.
Explanation:
The purpose of land reform and land colonization is to increase the global food supply and reduce malnourishment. So, the correct option is B.
What are land reforms?Land reforms mean the changes made or the changes that are needed to be made in order to ensure that agricultural land is fairly distributed. This is a change in the methods or rules of land ownership, management of owned land and how those methods further impact the public and economy in general.
This simply means the redistribution of agricultural land so that only a certain section of society cannot enjoy the benefits of land ownership.
This process has negatively impacted the environment as the unskilled settlers have been put in charge of managing agricultural land. They are unaware of the environmental impact that various activities can cause. For example burning of firewood, poor animal husbandry practices, land degradation etc.
Therefore, these reforms are used even when they have negative effects on the environment with the intent to increase the global food supply and reduce malnourishment.

Answer:
AlaskaWashingtonHawaiiCaliforniaOregonExplanation:
Eruptions along the western edge of the United States have formed the Cascades volcanic mountain range. Also, they develop island chains, such as the Aleutians in Alaska, which makes Alaska a potential volcanic eruption place. A prominent example of an eruption along the Ring of Fire was the dramatic eruption of Mount Saint Helens in Washington in 1980, which makes Washington a potential volcanic eruption state. Deep beneath Hawaii, there is a fixed source of abundant rising magma, called a hot spot, making Hawaii likely to be a volcanic eruption state. In 2018, they added Salton Buttes to the 2018 assessment, which is a high threat of a volcanic eruption. In other words, California is likely to be a volcanic eruption state. Eleven of the eighteen very high threat volcanoes are in Oregon, and few other states, where explosive and often snow- and ice-covered volcanoes can project dangerous long distances to densely populated and highly advanced areas.

Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that
influence life forms vary with location within ocean systems. Oceanographers divide the ocean into five broad
vertical zones as seen in the chart above. Compare the abiotic characteristics of the five zones.

forms found in the zones is supported by the information in the chart?
)
A)
Because of the severe abiotic conditions, there are no life forms found in
the hadalpelagic zone.
B)
The epipelagic zone is the only zone of the five zones where visible light
and algae can be found.
The mesopelagic zone hosts a diverse zooplankton community instead of a
phytoplankton or algae community and virtually no fish species.
Because there is no light in the abyssal zone, organisms feed on each other
or the dead organic material, detritus, that falls into the abyssal zone from
above.
D)
Answer:
B) The epipelagic zone is the only zone of the five zones where visible light and algae can be found.
Explanation:
A mesopelagic region has many different types of fish inhabit this twilight zone.
There are several organisms in the hadalpelagic zone.
The "abyssal zone" issue is meaningless because fish feed in all zones.

Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that
influence life forms vary with location within ocean systems. Oceanographers divide the ocean into five broad vertical
zones as seen in the chart above. Compare the characteristics of the five zones. The giant tube worms, Riftia
pachyptila, pictured here, have a red "plume at the tip of their free end which is an organ for exchanging compounds
with the environment. The tube worm does not have many predators. If threatened, the plume may be retracted into
the worm's protective tube. The plume provides essential nutrients to bacteria living inside the worm. Tube worms
have no digestive tract, but the bacteria, which may make up half of a worm's body weight, convert the oxygen,
hydrogen sulfide, carbon dioxide, taken in by the plume, into organic molecules on which their host worms feed.
Compare this information with the information in the chart. Where could these worms live?
A)
The tube worms can only live where there is no light: zones 3, 4, and 5.
B)
C)
Only in the top-most two zones so the bacteria can use the light for
photosynthesis.
In any zone in the ocean, provided it was not too cold and there is enough
oxygen in the water
They tube worms are suited to live in the halad zone only, where there is
no light and it is extremely cold.
D)
Answer:
D) They tube worms are suited to live in the halad zone only, where there is no light and it is extremely cold.
Explanation:
Although these tube worms reside in the trenches of the Halad zone at the lowest layer, they survive in darkness and freezing temperatures. Additionally, there are other species of starfish that inhabit this area, thus the starfish are also companions.
