D Correct answer
Explanation

Ozone depletion can lead to an increased risk of skin cancer, eye damage, and a weakened immune system due to the increased exposure to UV radiation.

Multiple choice

Which of the following is NOT a potential health impact of air pollution in rural areas?

  1. Respiratory problems

  2. Cardiovascular disease

  3. Cancer

  4. Heat-related illnesses
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Heat-related illnesses are typically associated with urban areas, where the urban heat island effect can lead to higher temperatures. In rural areas, air pollution is more likely to cause respiratory problems, cardiovascular disease, and cancer.

  1. Respiratory problems

  2. Cardiovascular diseases

  3. Cancer

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Air pollution from mining and quarrying can cause a range of health problems, including respiratory problems such as asthma and bronchitis, cardiovascular diseases such as heart attacks and strokes, and cancer. Exposure to air pollution can also increase the risk of premature death.

Multiple choice

What is the primary mechanism of ototoxicity caused by cisplatin?

  1. Interference with neurotransmitter release

  2. Inhibition of protein synthesis

  3. Damage to hair cells in the inner ear

  4. Blockage of ion channels in the cochlea
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cisplatin primarily causes ototoxicity by damaging the hair cells in the inner ear, which are responsible for hearing and balance. This damage can lead to hearing loss and vestibular dysfunction.

Multiple choice

What are some of the health effects of urban heat islands?

  1. Heatstroke.

  2. Dehydration.

  3. Respiratory problems.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Urban heat islands can have a number of negative health effects, including heatstroke, dehydration, and respiratory problems. Heatstroke is a condition that occurs when the body's temperature rises to dangerous levels. Dehydration occurs when the body does not have enough water. Respiratory problems can be caused by the high levels of air pollution that are often found in urban areas.
