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.

text to support your answer.
Answer:
The earth’s core affects the shape of the ground we
walk on.
Explanation: The earth’s core is responsible for
not only the Rocky Mountains, but the formation of cities and societies that have lived there for
generations, such as Rocky Mountain National Park. It’s responsible for mountains that serve as barriers,
bringing to life divisions in culture unique to each side, while also posing a challenge to be crossed and
burrowed into, spurring on scientific innovation in the process.
The Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.
What do you mean by the Earth's core?The Earth's core may be defined as the innermost layer of the Earth which is very hot and dense.
The Earth's core is responsible for any geographical locations like mountains, deserts, biodiversity hotspots, rivers, etc. It gives a structural appearance to the Earth. Human life is widely impacted and depends on all of these locations for their needs. All these geographical locations determine the climate of that particular area which is responsible for those people who are living at that location. Human life takes all its requirements from this core surface only.
Therefore, the Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.

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.

Cells are capable of reproducing themselves by cell division. For single celled organisms, cell division is essentially reproduction. For multicellular organisms, division is necessary for growth and renewal. Even though cell division is natural and necessary, what happens when the rate of cell division becomes too rapid and out of control? How can we get rid of such rapidly dividing cells in the human body?
Answer:
Here are 5 important things you should know about cancer cells:
1. Everyone has cancer cells in their body. These cells are not detected in routine tests until they have multiplied and grown to billions of cells.
2. Cancer cells are present in the body about 6-10 times in a person's lifetime.
3. When the immune system is healthy, cancer cells will be destroyed, preventing tumor growth and formation.
4. When a person has cancer, it means that he or she may be suffering from severe nutritional deficiencies or due to toxic environmental factors, unhealthy lifestyles and diets.
5. An effective way to fight cancer is to starve cancer cells by not providing them with the food they need to proliferate and grow.
"3 golden rules" help kill cancer cells:
1. Diet to prevent cancer
It can be said with certainty that there is no better way to keep your immune system healthy than with a reasonable and scientific diet. So ask yourself the question "Do you really have a reasonable diet to prevent cancer?". And here are the essential suggestions.
- Increase your diet with fresh vegetables, fruits, whole grains and foods high in fiber.
Eat more antioxidant foods: The fruits below are rich in antioxidants.
In addition, all vegetables and fruits contain a lot of vitamin A (carrot, papaya, tomato, sweet potato, pumpkin), vitamin C (orange, cherry, kiwi, strawberry), vitamin E (avocado, papaya). , cashews, peanuts, sunflower seeds, almonds...) are also foods with strong antioxidant capacity to help prevent cancer.
- Increase vitamin D supplementation.
Vitamin D is a special vitamin that is more important than all other vitamins because of its "universal" effect on the body's immune system. Its biological effects are related to the expression of more than 3000 genes in the body.
In addition to the extremely important role for the musculoskeletal system, the role of vitamin D in the prevention of many cancers and infectious diseases has been scientifically proven.
More than 90% of vitamin D in the body is synthesized in the skin under sunlight. Very little is absorbed from the diet, so the daily diet cannot guarantee the full amount of vitamin D needed by the body.
A recent study by a joint research team between the 108 Central Military Hospital and the University of Tuebingen (Germany) published in the journal BMC Infectious diseases showed that about 90% of healthy people are deficient in this vitamin. plasma vitamin D concentration <30 ng/ml).
Research also shows that there is a strong association between vitamin D deficiency and liver cancer in patients infected with hepatitis B. So the simplest way to ensure that you do not have a deficiency is to take vitamin D supplements. daily dose of 10-20 (µg/day) for all ages.
- Do not eat a lot of sugar and sweets because this is a food source that helps tumor growth. Sugar, not protein, is what tumors need to grow, so people with cancer still need the protein found in meat to boost their health against cancer. However, it should be noted that you should not eat a lot of red meat but should eat chicken and fish instead of beef and pork.
2. Increase physical activity
This is the most important principle of strengthening the immune system that anyone can do. The largest study conducted by the National Cancer Institute (USA) on more than 1.4 million people found that regular physical activity reduces the risk of 13 common types of cancer in humans.
The link between physical activity and reduced risk of many types of cancer can be explained by several key mechanisms:
- Strengthen the immune system, prevent the growth and spread of infectious agents.
- Physical activities help increase metabolism, improve circulation and help transport oxygen to all organs. Cancer cells must not grow in an oxygen-rich environment because oxygen can kill cancer cells.
Lowering levels of hormones such as insulin, estrogen and growth factors are thought to be closely related to cancer formation and development.
- Control weight, prevent obesity: Obesity is a leading risk factor for many types of cancer, metabolic disorders, cardiovascular diseases... It is estimated that more than 500,000 cancers are diagnosed each year. obesity-related diagnoses.
Increased blood flow to organs such as the liver, kidneys and intestines enhances the efficient elimination of waste products and toxins that can be potential causes of cancer from the body.
How do cells affect the size of an organism?
As animals grow in size, they produce more cells.
As cells expand or shrink, the size of an organism can change.
More cells can produce more chemical energy, allowing animals to get larger.
Larger cells produce larger-sized organisms.

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

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?
BiomeCommunityEcosystemHabitatWhich came first on planet earth, plants or animals
Answer:
We do not know entirely for sure
Explanation:
The vast majority of evidence points towards complex multicellular plants and animals evolving around the same time 500 million years ago during the Cambrian period. However, simple single-celled prokaryotic bacteria has been around for nearly a billion years. Personally I think it is more likely for plants to have come first as they are simpler and there seems to be a bit for evidence for them being first, like the discovery of multicellular algae that could be up to 1 billion years old (algae is generally considered to be bacteria)
It may be analyzed that land plants first appeared about 500 million years ago. It was the time of the Cambrian period. At this time, the development of multicellular animals does not begin at a systematic level.
When did the first prokaryotic cell was formed?The first prokaryotic cell was formed about 3.5 billion years ago. It was the time when no oxygen was present (anaerobic), the atmosphere was reduced, and the mode of nutrition was hetero chemotrophic.
The first eukaryotic cell was formed about 1.5 billion years ago which leads to the foundation of animal origination. It stimulates numerous changes with respect to the prokaryotic cell. But prior to that some land plants and fungi are already present which deliver the source of food to the developing living entities.
Therefore, according to researchers and scientists, it may be analyzed that the land plants exist before the animals through the help of the earliest fossils.
