Effects of pollution might includea. inability to see the top of skyscrapers because of the smog.b. acid rain-induced destructio
poizon [28]

Answer:

e. all of these answers

Explanation:

Air pollution in addition to affecting people, animals, plants and goods, causes other problems related to the changes that occur in its composition, such as: climate change, acid rain and the destruction of the ozone layer phenomena that affect the planet globally and that it is necessary to stop urgently by taking the necessary measures.

Main effects of pollution:

- Effects on human health : It is difficult to determine the exact relationships between exposure to air pollution and diseases developed in humans, especially in the long term, they are not known exactly, but there is evidence that high concentrations of pollutants in the atmosphere are a danger for the human being.  it can also act as a vector to spread diseases

- Effects on the environment :

It is in the natural environment where the first signs of the harmful effects of air pollution were seen, plants and vegetation act as an indicator in this regard.

Some of the most common contaminants :

SO2 ; O3 ; Fluorides ;  HCL; Cl2; NO2

- Effect on materials :

Contaminants can affect materials by particle deposition or abrasion and also by chemical reactions between the contaminant and the material. For example : stone, iron and paintings

- SMOG:

SMOG is known as fog-type pollution that occurs in some cities when the combination of certain factors occurs, depending on weather conditions and certain pollutants.

Some of them are:

Industrial smog

Photochemical smog

This phenomenon (SMOG) occurs when the mixture of nitrogen oxides and volatile hydrocarbons emitted by cars and industries and atmospheric oxygen react with solar radiation and form ozone.

- Acid deposition.

It is a regional effect. It results from the transformation of atmospheric pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) into secondary pollutants such as sulfuric acid (H2SO4), ammonium nitrate (NH4NO3) and nitric acid (HNO3).

Therefore, air pollution caused by SOx and NOx affects water, soil and ecosystems.

- Water contamination

Pollution of the waters of a sick river and kill fish, but not only these, but all forms of aquatic life .

Pesticides and other toxic chemicals that are used in the domestic environment, farms and industrial production, and that are dumped into the water, cause fish death.

Which is not a component of the balanced and restorative justice model?
andrew11 [14]

Deconstructionism is not a component of balanced and restorative justice model.

Balanced and restorative justice is termed as the theoretical model and attempts to span tension between treatment and retribution. In this process victims takes an active role. Offenders take full responsibility for their actions.

Seize an opportunity to do right from wrong and redeem themselves before their community and before their eyes. Restorative justice focuses on helping offenders from future offences.

Which of the following statements is true?
Lelu [443]

Answer:

The true statement is: "Spring tides are the highest, while neap tides are the lowest."

Explanation:

  • The range of difference in the level of water between high and low tide is always larger in spring tide.
  • Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun)  balances the bulge of the ocean caused by the moon.
  • This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.

Pre-Lab Questions What are two ways that some prokaryotes are able to survive in extreme environments? Describe three ways that
il63 [147K]

What are two ways that some prokaryotes are able to survive in extreme environments?

Answer:

1. Presence of thick cell wall in prokaryotes help them to survive in hypo-osmotic and hyper-osmotic conditions.

2. Production of endospores by bacteria. Bacteria use these structures to produce off sprigs because these structures are heat and drought resistant. They germinate when the conditions became favorable for growth.

Describe three ways that microorganisms in soil contribute to the ecosystem as a whole.

Answer:

1. As decomposer return the nitrogen contents back to ecosystem.

2. Bacteria detoxify may harmful substances present in water bodies therefore some species of bacteria are used for bio-remediation of ecosystem.

3. Bacterial byproducts help plant to grow faster because these byproducts act as stimuli for plant growth.

Give two examples of genera that produce endospores, and explain why they are important in human health.

Answer:

Endospore Producing Genus:

Bacteria belongs to genus Bacillus and Clostridium produce endospores.  

Importance for humans.:

1. Bacillus species are used to produce antibiotics, metabolites, enzymes which help in curing human diseases.

2. While species of Clostridium cause food poisoning in human.

What are coliforms? Why are they important in assuring water quality?

Answer:

Coliforms are gram negative bacteria have road like shape found in spoiled water.  

Importance:

These bacteria are important indicator of polluted water therefore in water quality testing their presence tells us about the water quality that how much is this water polluted.

Why is E. coli the indicator bacterium for fecal contamination?

Answer:

E. Coli found in the intestine of humans. As E. Coli itself does not cause mild infections therefore its presence indicates the presence if other deadly pathogens which may cause dangerous diseases to human.
