Answer:
Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.
Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.
Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.
"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

Which of the following might be an adaptation for a predator? AS SOON AS POSSIBLE NEED HELP PLS THX
Answer:
we need the answers
Explanation:
Answer:
Many predators have adaptations that help them survive in the wild. For example, the snake shown below has camoflauge coloring to look like its surroundings. This gives it the element of surprise when going to attack its prey. These adaptations help the predator in hunting for food. Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws. The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

What happens to the chromosomes when a cell divides to make a copy of itself?
Answer:
the cell copies or replicates its chromosomes and then splits the copied chromosomes equally to make sure each daughter cell has a full set.
Answer:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies or "replicates" it's chromosomes and then splits the copied chromosomes equally to make sure that each. daughter cell has a full set.

How are humans changing the carbon der
Lesson 1.10
all of the choices
Answer:
Human activities affect the carbon cycle through emissions of carbon dioxide (sources) and removal of carbon dioxide (sinks). The carbon cycle can be affected when carbon dioxide is either released into the atmosphere or removed from the atmosphere.

High cholesterol and triglycerides may indicate cardiovascular disease. What happens when cholesterol and other lipids are deposited in artery walls?
Answer:
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
plants experience _______ gravitropism when their stems move upward.
A. positive
B. negative
Answer:
Negative
Explanation:
Gravitropisms. Phototropism is a response to the stimulus of light, whereas gravitropism (also called geotropism) is a response to the stimulus of gravity . When the stem grows against the force of gravity (upwards), this is known as a negative gravitropism.
Answer:
negative
Explanation:
this is because negative gravitropism is when a plant grows away from gravity (like moving upwards). then, positive gravitropism is when the roots of a plant move grow downwards.

Contrast the terms “parasitism” and “mutualism” in a sentence
Answer:
Explanation:
Mutualism is the interaction between two or more organisms where both organisms can benefit from the interaction while Parasitism is the interaction between two species where only one benefits from the other organism and the other is harmed in return
Answer:
When both the partners or organisms get benefits from one another by living together is known mutualism. When only one partner or organism gets benefits without any effect on the other is commensalism. When one partner or organism gets benefits while the other is harmed is known as parasitism.
Identify how scientists use radioactive isotopes by selecting the best answers from the drop-down menus.
Archaeologists use radioactive isotopes to
.
Scientists use radioactive isotopes in agriculture to
.
Geologists use radioactive isotopes to
.
Answer:
1. Archaeologist use radioactive isotopes to determine the ages of various objects, rocks and materials. This is called radioactive dating. Radioactive isotope Carbon-14 is widely used for this dating process.
2. Scientists use radioactive isotopes in agriculture to monitor or study the uptake and use of essential nutrients by plants from the soil. This helps to determine viability, productivity and nutritious ability of the plants on a piece of land.
3. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events. ... Atoms of the same element but with different number of neutrons are called isotopes of that element.
Answer:C: Determine the age of ancient artifacts.A: Understand the biological and chemical processes in plants.B: Determine the age of rocks and fossils.

Explain how scientists use geologic time to determine the age of landforms.
geologic time use the layer of Rock to describe relationship of events and their sequence chronological order over the history of Earth the layering is a result of the buildingup tiny beats of rocks sediments or Lava cooling at the surface of many years think think of it like a stock of pancakes-the bottom layer is the one that was placed first and therefore is the oldest. the sediments that create the layer of the earth as said one or top of the other
which statement correctly describes greenhouse gases in the atmosphere?
Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Explanation:
Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.

How do you think that wearing personal protective equipment helps to protect us from contracting airborne diseases?
Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.
