Question

22 multiple choice 4 points what is the primary health impact of exposure to particulate matter (pm) as a primary air pollutant? gastrointestinal problems and food poisoning skin rashes and eye irritation respiratory irritation and lung cancer cardiovascular diseases and obesity 23 multiple choice 4 points what ocean does enso happen in? atlantic pacific indian arctic 24 multiple choice 4 points which renewable energy source involves converting sunlight into electricity? biomass energy solar power tidal power geothermal energy

Explanation:

• For question 22: Particulate matter (PM) is inhaled, so it primarily affects the respiratory system. Respiratory irritation and increased risk of lung cancer are well - known impacts. Gastrointestinal issues (from ingestion), skin/eye irritation (from contact, less common for PM as a primary effect), and obesity (not directly related to PM inhalation) are less relevant.
• For question 23: ENSO (El Niño - Southern Oscillation) occurs in the Pacific Ocean. It is a climate pattern characterized by variations in sea surface temperatures and atmospheric pressure in the tropical Pacific.
• For question 24: Solar power directly converts sunlight (solar radiation) into electricity, for example, through photovoltaic cells. Biomass uses organic matter, tidal uses ocean tides, and geothermal uses heat from the Earth's interior.

Answer:

1. Respiratory irritation and lung cancer
2. Pacific
3. Solar power
