c. Some health risks are increased by heredity, which manifest under certain environmental conditions.
<h3>The chance of contracting some diseases can arise in particular circumstances.</h3>
The occurrence of certain diseases is influenced by certain environmental factors. Air pollution from a polluted environment increases the chance of allergic people or those with overactive immune systems acquiring respiratory conditions like asthma. A similar genetic flaw in melanin formation increases the risk of skin cancer in people who are exposed to UV rays. As a result, certain circumstances promote the development of disease.
Communities can lessen exposure to diseases and chemicals that have damaging effects on the body by focusing on environmental health. Environmental health treatments can improve everyone's quality of life, but they may be especially noticeable for people with pre-existing health conditions.

C) Extensive Property
An extensive property is a property that depends on the amount of matter in a sample. The mass of an object is a measure of the amount of matter that an object contains.
Answer:
108.9g of Silver can be produced from 125g of Ag2S
Explanation:
The compound Ag2S shows that two atoms of Silver Ag, combined with an atom of Sulphur S to form Ag2S. We can as well say the combination ration of Silver to Sulphur is 2:1
•Now we need to calculate the molecular weight of this compound by summing up the molar masses of each element in the compound.
•Molar mass of Silver Ag= 107.9g/mol
•Molar mass of Sulphur S= 32g/mol
•Molecular weight of Ag2S= (2×107.9g/mol) + 32g/mol
•Molecular weight of Ag2S= 215.8g/mol + 32g/mol= 247.8g/mol
•From our calculations, we know that 215.8g/mol of Ag is present in 247.8g/mol of Ag2S
If 247.8g Ag2S produced 215.8g Ag
125g Ag2S will produce xg Ag
cross multiplying we have
xg= 215.8g × 125g / 247.8g
xg= 26975g/247.8
xg= 108.85g
Therefore, 108.9g of Silver can be produced from 125g of Ag2S
