One is through turgidity. this occurs before ground tissue ( collenchyma and sclerenchyma cells) become well developed to give structural support to the plant as it grows bigger. The xylem tissue (composed of rigid tissue) of the young plant render this support and also maintaining osmotic turgidity of the surrounding plant cells.
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.

I would say immigration only.
emigration would theoretically reduce the genetic variation as unique individuals leave, but immigration would bring unique traits into circulation in an ecosystem.
I'm not super great at biogy tho so this might not be right... :)
Histamines are chemicals released by the body as an allergic response.They help the body by reacting when their are "intruders" so when enters, histamine acts as a messenger and sends out a signal for the body to create a reaction helping to get rid of teh intruder through some type of reaction.
