Question 1: Which gas is most important for the process of photosynthesis?
Question 2: Which country was the first to grant women the right to vote?
New Zealand granted women the right to vote in 1893, becoming the first self-governing country to do so. This was a landmark moment for women's suffrage movements around the world.
Question 3: Which molecule is the primary carrier of genetic information in all living organisms?
DNA, or deoxyribonucleic acid, contains the instructions needed for an organism to develop, survive, and reproduce. It is organized into chromosomes and found inside the cell nucleus of eukaryotic organisms and in the cytoplasm of prokaryotic organisms. DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Question 4: What is the absolute value of negative five?
The absolute value of a number refers to its distance from zero on the number line without considering which direction from zero the number lies. Consequently, the absolute value of negative five is five.
Question 5: In which country was the ancient Inca city of Machu Picchu discovered?
Machu Picchu was rediscovered in 1911 by Hiram Bingham, an American historian. It's situated on a mountain ridge above the Urubamba Valley in Peru and is one of the most iconic and well-preserved archaeological sites of the Inca civilization.
Question 6: Why are honeybees considered important to agriculture?
Honeybees play a critical role in agriculture as pollinators. Approximately one-third of the food that humans consume each day relies on pollination by bees, particularly fruits, vegetables, and nuts.
Question 7: What is the value of the mathematical constant Pi to two decimal places?
Pi is an irrational number and cannot be expressed exactly as a simple fraction. It's approximately equal to 3.14 but extends infinitely without repeating, often used in mathematics to represent the ratio of a circle's circumference to its diameter.
Question 8: Which company introduced the first commercially available hybrid gasoline-electric car?
The Toyota Prius was introduced in Japan in 1997, and later globally in 2000. It was the world's first mass-produced hybrid car, combining a gasoline engine with an electric motor to increase fuel efficiency.
Question 9: The poison of which spider is considered the most toxic to humans?
The Brazilian wandering spider, also called the banana spider, has venom potent enough to cause serious injury or death to humans; however, this spider is not eager to bite, and antivenom is available.
Question 10: The "Hand of God" goal was scored by which footballer?
The "Hand of God" goal was scored by Diego Maradona during the 1986 FIFA World Cup quarter-final match between Argentina and England. Maradona's punch of the ball went unnoticed by the referee, and the goal stood, contributing to Argentina's 2-1 victory.
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) to create glucose (a sugar that serves as their food) and release oxygen (O2) as a byproduct. This process is crucial not only for the survival of plants but also for maintaining atmospheric oxygen levels for other living organisms.
