write a report on storm around the world​

Answers

The U.S. central plains region -- nicknamed Tornado Alley -- suffers the highest frequency of tornadoes in the world [source: Tarbuck]. Many of these twisters leave death, injury and destruction in their wake, but one stands in a class by itself.

Sweeping out from southeastern Missouri on March 18, 1925, the Tri-State Tornado careened across the southern tip of Illinois before dissipating in lower Indiana. Remarkably, these three locales lie 219 miles (352 kilometers) apart, and the tornado traveled this distance in just three and a half hours [source: SEMP].
With up to 155-mph winds, Hurricane Iota smashed record books on Nov. 16 as the strongest hurricane ever recorded to make landfall in Nicaragua. Iota reached Category 5 strength before making landfall as a Category 4 storm near the town of Haulover, Nicaragua.

The onslaught of destructive winds and heavy rainfall was unfortunately familiar to a region that recently suffered another Category 4 landfalling storm – Hurricane Eta – just two weeks earlier. Eta was a Category 4 storm with 140-mph winds when it landed in Nicaragua on Nov. 3 before ripping a wide path of destruction through Honduras and Guatemala.

Heavy rainfall from these two storm systems brought widespread flooding to the region, triggered large and numerous landslides in Guatemala and Honduras, and was responsible for numerous casualties.

NASA’s Earth Applied Sciences Disasters Program supports disaster response and risk reduction efforts throughout the world — before, during, and after disasters strike – and is working to aid Central America with the impacts from these storms.

In the case of Eta and Iota, the Program is using imagery and data from Earth-observing satellites to provide scientific analysis to Guatemala’s National Coordinator for Disaster Reduction and is working with the Coordination Center for Disaster Prevention in Central America. The multi-agency collaboration is assisting local governments in Nicaragua, Honduras and Guatemala, El Salvador, Belize, Costa Rica, and Panama. The Program is also working with U.S. Southern Command to provide situational awareness for potential emergency humanitarian assistance.

Empty stomachs contract, causing both hunger pangs and the secretion of chemical messages that travel to the brain to serve as a signal to initiate feeding behavior. This is an example of ________. Group of answer choices

Answers

Answer:

How physiological mechanisms serve as the basis for hunger

Explanation:

Physiological mechanisms are able to provide explanations to body functions, events and outcomes. Such mechanisms could be altered voluntarily when there's the need to. Hunger is on example of such. When a person is hungry the muscles of the stomach contracts and messages are sent to the brain. This process is what tells the person thaat he needs to feed.

Organisms use glucose to store and transport energy.
True
False

Answers

Answer:

Glucose and ATP are used for energy by nearly all living things. Glucose is used to store and transport energy, and ATP is used to power life processes inside cells. Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose.

Explanation:

Most organisms use glucose and ATP for energy. ATP powers cells, and glucose stores and transports energy. Photosynthesis converts sunlight into glucose for many autotrophs.

What do organisms use to store and transport energy?

All living things use ATP and glucose as energy sources. Energy is stored and transported by glucose, and cellular life functions are powered by ATP. Through the process of photosynthesis, which converts solar light energy into chemical energy that is stored in glucose, many autotrophs produce food.

Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules. Glycogen is broken down to release glucose into the bloodstream, which is then used as fuel for the cells, when the body needs a sudden surge of energy or when the body isn't obtaining glucose from food.

How many capillary beds must a red blood cell pass through to move from an artery in the left arm to the left ventricle of the heart

Answers

Answer:

two capillary beds

Explanation:

Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.

Answers

Answer:

nucleus

Explanation:

The organelle would most likely be the nucleus.

The nucleus happens to be a membrane-bound organelle that is somehow round in shape. It houses most of the genetic components of the cell, including proteins and nucleic acids in the form of DNA.

Fungi themselves belong to the eukaryotic category of living organisms and as such, every fungus cell is expected to have a nucleus and other membrane bound organelles such as mitochondrion.

Hence, the organelle would most likely be the nucleus of the fungi cell.

What are the positive effects human activities on vegetation?​

Answers

Answer:

Vegetation cover is also significantly impacted by human activities. Changes in land use resulting from human activities such as urbanization and agriculture are important factors influencing the spatial pattern of vegetation.

Answer:

Vegetation plays a vital role in our natural ecosystem and also supports the biosphere in various ways; vegetation helps to regulate the flow of numerous biogeochemical cycles, most importantly those of water, carbon, and nitrogen; it also contributes in the local and global energy balances. With the continuous increase in the population, the negative impact of human activities on the ecological environment is also increasing, such as overgrazing caused by the rapid increase of livestock.

Genetic engineering can be used to create more productive strains of farm animals used for milk and meat production. By adding genes to an animal’s DNA, the animal can be made to be more resistant to common infections. This can reduce the need to administer large doses of antibiotics to the animals.

Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)

What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)

Answer:

Yes.

Explanation:

Yes, this type of genetic engineering should be pursued in order to avoid decrease in death through infections or diseases as well as increase the production of milk and meat of that animals. With this genetic engineering, organisms have high resistance to diseases which decrease the cost of antibiotics. The positive effect of this genetic engineering is the increase in the resistance that leads to good health as well as productivity of organism.
