Answer:
The correct answer is- Preeclampsia
Explanation:
Preeclampsia is a complication during pregnancy which is characterized by high blood pressure in the pregnant woman and damage to internal organs like liver and kidney.
This complication starts normally after 20 weeks of the pregnancy. Before starting preeclampsia the pregnant woman's blood pressure is normal. Preeclampsia can lead to serious complications if it untreated and the delivery of the baby is the most effective treatment.  
Therefore preeclampsia is a life-threatening disease, characterized by high blood pressure in pregnant women.

How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
by increasing carbon dioxide and decreasing oxygen 
by increasing carbon dioxide and increasing oxygen 
by decreasing carbon dioxide and increasing oxygen 
by decreasing carbon dioxide and decreasing oxygen
 
The answer to this question is by increasing carbon dioxide and decreasing oxygen.
Explanation:
Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.
In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.
