Answer the following question given this paragraph: Light microscopes allow biologists to see small details of a specimen. Most of the microscopes used in schools and laboratories are light microscopes. Light microscopes use lenses, typically made of glass or plastic, to focus light either into the eye, a camera, or some other light detector. The most powerful light microscopes can make images up to 2,000 times larger. Q: How much larger can the most powerful light microscropes make an image? Choices: - 500 times - 10 times - 100 times - 2000 times A:
2000 times
Answer the following question given this paragraph: The Water (Hydrologic) Cycle Water is the basis of all living processes. The human body is more than 1/2 water and human cells are more than 70 percent water. Thus, most land animals need a supply of fresh water to survive. However, when examining the stores of water on Earth, 97.5 percent of it is non-potable salt water (Figure 46.12). Of the remaining water, 99 percent is locked underground as water or as ice. Thus, less than 1 percent of fresh water is easily accessible from lakes and rivers. Many living things, such as plants, animals, and fungi, are dependent on the small amount of fresh surface water supply, a lack of which can have massive effects on ecosystem dynamics. Humans, of course, have developed technologies to increase water availability, such as digging wells to harvest groundwater, storing rainwater, and using desalination to obtain drinkable water from the ocean. Although this pursuit of drinkable water has been ongoing throughout human history, the supply of fresh water is still a major issue in modern times. Q: The primary substance that human cells, and ultimately human beings, are made up of is what? Choices: - air - oil - gas - water A:
water
Q: Answer the following question given this paragraph: Another amazing feature on the Sun is solar prominences. Plasma flows along the loop that connects sunspots. This plasma forms a glowing arch. The arch is a solar prominence. Solar prominences can reach thousands of kilometers into the Sun's atmosphere. Prominences can last for a day to several months. Prominences can be seen during a total solar eclipse. Q: What is the arch called that forms when plasma of the sun flows along the loop that connects sunspots? Choices: - Energy prominence. - vertical prominence - large prominence - solar prominence A:
A: solar prominence
Question: Answer the following question given this paragraph: Two forces may act on an object in the same direction. You can see an example of this in Figure below . After the man on the left lifts up the couch, he will push the couch to the right with a force of 25 newtons. At the same time, the man to the right is pulling the couch to the right with a force of 20 newtons. When two forces act in the same direction, the net force is equal to the sum of the forces. This always results in a stronger force than either of the individual forces alone. In this case, the net force on the couch is 45 newtons to the right, so the couch will move to the right. Q: What is the net force when two forces act in the same direction? Choices: - number of the forces - arguing forces - group of forces - sum of the forces A:
Answer: sum of the forces
