What has happened to Earth due to the pollution?
Answer:
OCEAN LITTER
Litter in the world’s oceans comes from many sources, including containers that fall off ships during storms, trash that washes off city streets into rivers that lead into the sea, and waste from landfills that blows into streams or directly into the ocean. Once in the ocean, this debris may degrade slowly and persist for years, traveling the currents, accumulating in large patches and washing up on beaches.
PESTICIDES AND FERTILIZERS
Use of pesticides and fertilizers on farms has increased by 26-fold over the past 50 years, fueling increases in crop production globally. But there have been serious environmental consequences. Indiscriminate pesticide and fertilizer application may pollute nearby land and water, and chemicals may wash into nearby streams, waterways and groundwater when it rains. Pesticides can kill non-target organisms, including beneficial insects, soil bacteria and fish. Fertilizers are not directly toxic, but their presence can alter the nutrient system in freshwater and marine areas. This alteration can result in an explosive growth of algae due to excess nutrients. As a result, the water is depleted of dissolved oxygen, and fish and other aquatic life may be killed
AIR POLLUTION
Air pollution brings to mind visions of smokestacks billowing black clouds into the sky, but this pollution comes in many forms. The burning of fossil fuels, in both energy plants and vehicles, releases massive amounts of carbon dioxide into the atmosphere, causing climate change. Industrial processes also emit particulate matter, such as sulfur dioxide, carbon monoxide and other noxious gases. Indoor areas can become polluted by emissions from smoking and cooking. Some of these chemicals, when released into the air, contribute to smog and acid rain. Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease. Long-term exposures also can lead to significant climatic changes that can have far reaching negative impacts on food, water and ecosystems.
NOISE AND LIGHT POLLUTION
Artificial light and noise often drown out natural landscapes. In the Arctic, the sounds of oil and gas explorations are so loud that belugas, bowhead whales and other sea life have had difficulty feeding and breeding. Light pollution disrupts circadian rhythms for both humans and animals alike and may even contribute to the development of cancer. Light pollution also can impact sea turtles. Adult and hatchling sea turtles are drawn toward lights along the beach, thinking they are heading toward the moon. Coastal developments, therefore, are encouraged to turn off their lights or cover them at night

The Haunted Forest
Once upon a time there was a family, made up of two young ones and their parents, traveling by road to road. One day the car broke down in the forest. The parents went out to get help, and so the children would not get bored, they left them with the radio on. It turned night time and the parents still did not return. Then suddenly they heard the disturbing news go on in the radio: A very dangerous killer had escaped from a prison near the forest. Hours passed and the children's parents did not come back. Suddenly, they began to hear something really loud. ¨Bang, Bang, Bang¨. They heard that which seemed to come from something hitting the top of the car. Then, the sound became louder and louder every time. ¨BANG, BANG, BANG¨. The terrified children could no longer resist. They opened the door and ran in a hurry. Only the eldest of the children dared to turn his head to see what caused the loud noise. He should have not done it though, there was a large and scary man on top of the car, who hit the top of the vehicle with something on his hands, they were the heads of his parents! The children began to run even faster and the large man began to run towards them. The children ran into the forest and so did the large man. After that day no one ever saw those children ever again, and who knows, they may appear mysteriously next to you.
Hope you enjoyed!! ;)

Explanation:
Which best describes the way a sound wave is sent through the radio?
sound wave → radio wave
radio wave → sound wave
radio wave → sound wave → electrical signal → sound wave
sound wave → electrical signal → radio wave → sound wave
Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.
What is a sound wave?A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.
The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.
These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.
Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

What is the relationship between capillaries and lymph vessels
Answer Blood vessels deliver oxygen and nutrients to virtually all cells in developing mammalian embryos and adults, whereas lymphatic vessels drain the interstitial fluid that collects in tissues, and serve as a conduit for immune cell trafficking and fat absorption.
: Lymphatic capillaries collect lymph fluid from the tissues, which allows them to regulate the pressure of interstitial fluid. This fluid is essentially plasma that leaks out of cardiovascular capillaries into the tissues due to the forces of hydrostatic or oncotic pressure.

Just as slow-moving water loses sediment, fast-moving water can pick up new sediment to carry. Which part of the river
bend will experience the greatest amount of new erosion? How will this erosion affect the shape of the river?
Answer:
The part of a riverbend that will experience the most erosion is the inside corner, this is because the water will be hitting it on two sides, the erosion will likely curve the inside corner more.
The water flowing at the maximum velocity and with the greatest ability to erode is on the outside of the curve, rivers that meander erode in both directions.
What factors affect the river?Cut bank erosion occurs when the edge of a stream channel bends, and it increases the loop of the meander, water that moves more quickly has greater kinetic energy.
It can therefore transport bigger particles, more articles may also be carried by it, and bigger and larger particles can be carried by a stream as it moves more quickly. The capacity of a stream increases with the size of the particles it can transport.
Therefore, a stream will have a quicker velocity if it has a steep slope or gradient, which implies it may transport heavier items in suspension.

Some of the key factors that make North Carolina attractive for the biotechnology industry include:
the presence of the pioneering North Carolina Biotechnology Center and Research Triangle Park have lead to financial incentives the state government has provided to companies such as Merck and Quintiles; and the educational programs developed at both the community college and university level to help firms fill openings with qualified local employees with knowledge and training in biotechnology.
Tax revenues increase because of the large number of developing careers in the field of biotechnology in North Carolina.
Biotechnology affects us in every area of our lives, our food, water, medicine and shelter, improving quality of life. When it comes to Biotechnology, nothing could be finer than to live in North Carolina!
Answer:
look at Explanation
Explanation:
North Carolina’s biotech industry is quickly expanding.
Within the state, there are more than 600 life science companies employing 61,000 people at an average salary exceeding $81,000 a year – which is nearly twice the state’s overall private sector wage, according to the North Carolina Biotechnology Center.
In total, life science companies and institutions in North Carolina generate $73 billion in economic activity, which is an increase of 23 percent in two years, and account for 228,259 direct and indirect jobs, says North Carolina Biotechnology Center.
Furthermore, while employment in the nation’s life science industry rose by 7.4 percent from 2001 to 2012, North Carolina’s grew at a surprising 31 percent, even with setbacks from the Great Recession of 2008.
Following closely behind California, North Carolina outpaced life science industry growth in other states, including Texas, New York, Massachusetts and Florida, between 2009-2012, according to the U.S. Bureau of Labor Statistics. In the chart below, North Carolina's life science industry grew 5.2% from 2009 to 2012. While California's life sciences industry increased even more at 5.5% during the same time period, other states such as Pennsylvania and New Jersey actually saw their life sciences sectors shrink by 7% and 7.3%, respectively.
