(01.01 MC)

Answer 1

Science can answer Question 1. It cannot answer Question 2.

Question 1

Scientists can give different amounts of arsenic to test subjects and measure its effects on their DNA.

Question 2

Scientists can measure the amount of heavy metal that an industry releases into the environment. However, they cannot make value judgements.

The politicians must be the people who make the value judgement on who  should pay the cost of cleanup.

Answer 2

Answer:

Yes, both the questions can be answered by the science.

Explanation:

1. The heavy metals like arsenic and leads can increase the production of reactive oxygen species in humans. These heavy metals causes single strand break in the DNA. Arsenic and lead metals can cause base pair mutation in DNA that can cause different types of cancer in human beings. Science can explain the damage caused by the heavy metals by performing experiments and by the use of molecular techniques.

2. The industries that release heavy metals should be penalized because these heavy metal remain persist in the environment. These heavy metal cause soil and water pollution. The persistence of heavy metals can cause death of aquatic life and its persistence in human body can leads to different types of cancer.
