Starting in 1887, what was used by miners to extract gold from ore in a process called leaching?
- A.
Leaches
- B.
Cyanide
- C.
Milk
- D.
Chlorine bleach
Correct Answer
B. CyanideExplanation
In the late 19th century, miners began using cyanide to extract gold from ore in a process known as leaching. Cyanide is a highly effective chemical compound that dissolves gold and allows it to be separated from the surrounding rock and other impurities. This method revolutionized the mining industry as it provided a more efficient and cost-effective way to extract gold from large quantities of ore. The use of cyanide in gold extraction continues to be a common practice in modern mining operations.Rate this question:

What was the Manhattan Project of the 1940's?
- A.
The project that led the Americans to discover the atomic bomb
- B.
The conception, design and landscaping of Central Park in NYC
- C.
A coalition of international scientists who collaborated on solving world issues of pollution
- D.
The project behind the discovery of the structure of DNA, the heredity molecule
- E.
I don't know
Correct Answer
A. The project that led the Americans to discover the atomic bombExplanation
The Manhattan Project was a top-secret research and development project during World War II that aimed to develop the first atomic bomb. It involved a collaboration of American scientists, engineers, and military personnel who worked together to harness nuclear energy and create a weapon of immense destructive power. The project ultimately led to the successful testing and deployment of the atomic bomb, which was used by the United States against Japan in 1945.Rate this question:

Filtering tap water through activated carbon removes _______ ?
- A.
Dissolved calcium
- B.
Nitrates
- C.
Bad tastes, odours, and color
- D.
Viruses
Correct Answer
C. Bad tastes, odours, and colorExplanation
Filtering tap water through activated carbon removes bad tastes, odors, and color. Activated carbon has a porous structure that helps to trap and absorb impurities in the water. It is particularly effective in removing organic compounds that can cause unpleasant tastes, odors, and discoloration. However, it does not remove dissolved calcium, nitrates, or viruses, as these substances require different filtration methods or treatments.Rate this question:

Gregor Mendel, an Austrian monk founded the science of genetics by studying the hereditary traits of ......
- A.
Guinea pigs
- B.
Apples
- C.
Chickens
- D.
Peas
- E.
Worms
Correct Answer
D. PeasExplanation
Gregor Mendel founded the science of genetics by studying the hereditary traits of peas. Through his experiments, Mendel discovered the principles of inheritance, including dominant and recessive traits, as well as the concept of genetic variation. Mendel's work with peas laid the foundation for our understanding of genetics and paved the way for future research in the field.Rate this question:

What is dendrochronology?
- A.
A method of determining the age of wood by examining the tree growth rings
- B.
Using the well-known format of the family tree to document family histories.
- C.
The study of the hair and the scalp
- D.
A system by which trees are classified
- E.
I don't know
Correct Answer
A. A method of determining the age of wood by examining the tree growth ringsExplanation
Dendrochronology is the scientific method of determining the age of wood by examining the tree growth rings. By analyzing the patterns of growth rings in a tree's cross-section, scientists can determine the age of the wood and gain insights into past climate conditions and environmental changes. This method is widely used in archaeology, ecology, and climatology to date wooden artifacts, reconstruct past environments, and study long-term climate patterns.Rate this question:

Which of the following statements about acid rain is NOT true?
- A.
Lakes in limestone areas can neutralize the acid to varying degrees
- B.

- C.
One rainfall will elevate the acidity of a lake to damaging proportions
- D.
Acid rain can damage soil, too
- E.
Acid rain existed long before man-made technologies did
Correct Answer
C. One rainfall will elevate the acidity of a lake to damaging proportionsExplanation
Acid rain can indeed damage lakes and their ecosystems over time, but it typically takes multiple instances of acid rain to significantly elevate the acidity of a lake to damaging proportions. One rainfall alone is unlikely to cause immediate and severe damage.Rate this question:

Fog near Los Angeles has been measured to be as acidic as vinegar.
- A.
True
- B.
False
- C.
I don't know
Correct Answer
A. TrueExplanation
The given statement is true. Fog near Los Angeles has been measured to be as acidic as vinegar. This means that the pH level of the fog is very low, similar to the acidity level of vinegar. The high levels of air pollution in the Los Angeles area contribute to the acidity of the fog, which can have negative effects on the environment and human health.Rate this question:
