Explanation:
Question 1
Air pollution is the introduction of harmful gases and substances into the atmosphere that renders it unfit for use for life. Some of these toxic gases and particulates are:
- Carbon monoxide
- Carbon dioxide
- Nitrogen oxides
- Smoke
- Dust particles
- Soot
Question 2
Natural forms are the original nature or outlook of a substance. Examples of natural forms are:
- Flowers
- Leaves
- Animals
- Rocks
- Shells
- Corals
Question 3
Anthropogenic cause of pollution are human causes of pollution. Some of these are:
- Combustion of fossil fuels in internal combustion engines release harmful and toxic gases into the atmosphere and causes hair pollution.
- Improper disposal of waste can produce effluent that reaches the ground water system and other fresh water sources.
- Noise pollution from airports is very harmful to ear.
- Mining activities degrades soil and removes rich fertile soils that should be used for agriculture.
- Mining wastes can lead to contamination of water bodies around.
Question 4
Fossil fuels are fuel types that forms from natural process in which organisms are decomposed anaerobically to preserve their energy components. Some of these fuels are:
Question 5
- Heart diseases ; ischaemic heart diseases can lead to failure of the heart when it does not receive enough oxygen from the environment. Air pollution contaminates available oxygen in the atmosphere and this is very dangerous to life.
- Lung cancer: poor air quality can lead to the development of cancerous tumor in the lungs.
- Asthma: air pollution is one of the leading cause of asthma.
Other notable mentions are bronchitis, pulmonary diseases, stroke
Question 6
_7 million____ people die each year from air pollution according to the world health organization
Question 7
Air Quality Index(AQI) is an indicator used to express the quality of air in particular area. The AQI can tell the present air quality condition. It can also be used to forecast future air quality in years to come.
It shows how clean and polluted the air is.
Question 8
The air quality index uses different colors to alert people about the quality of air. Each color represents different health implication of air quality:
Attached image shows the different colors used to alert people of about the air quality.
Question 9
- About 7 million people die annually as a result of air pollution
- Beijing cough is new disease that emanates from the rising air pollution in Beijing
- Asia has the fastest rising cases of air pollution problems.
- The best way to reduce air pollution is by riding bicycles and walking more.

The correct answer is - a front.
On this image, the lines are representing a front, and since the signs are marked with blue color, it means that it is a cold front. The fronts are advancing masses of air. In this case, we have a cold front, thus we have advancing cold air masses in the western part of the US, and in the Great Lakes region and the northeastern part of the country. This means that these areas will be affected by colder air masses, that will bring in higher air pressure, colder weather, and cold winds from the direction from which these cold fronts are coming.
Answer:
Due to presence at early days of the planet.
Explanation:
We only find the remains of single celled organisms in the oldest fossils because the single celled organisms are the organisms that were present in the early days of this planet. These single celled microbes were present about 3.7 billion years ago while on the other hand, the oldest rocks are only a little older i. e. 3.8 billion years so these single celled organisms are considered as oldest fossils on this planet.
It is known as a transgenic organism. This procedure is otherwise called "genetic engineering." Genes of one species can be altered, or qualities can be transplanted starting with one animal types then onto the next. Genetic engineering is made conceivable by recombinant DNA innovation. Living beings that have modified genomes are known as transgenic.
<span>Bone marrow which is located <span>within the spongy or cancellous portions of bones is the essential site of new blood cell production or hematopoiesis. Bone marrow contains stem cells which able to differentiate into specialized cell types. People with diseases like blood cancers, such as leukaemia and lymphoma, sickle cell anaemia, and other rely on bone marrow transplantation to survive.</span></span>
