Answer the following question given this paragraph: The girls in the picture above make up a small samplethere are only four of them. In scientific investigations, samples may include hundreds or even thousands of people or other objects of study. Especially when samples are very large, it's important to be able to summarize their overall characteristics with a few numbers. That's where descriptive statistics come in. Descriptive statistics are measures that show the central tendency, or center, of a sample or the variation in a sample. Q: In scientific investigations, descriptive statistics are useful for summarizing the characteristics of large what? Choices: - organisms - questions - tissues - samples A:
(Answer)
samples
Ques: Answer the following question given this paragraph: The whirring blades of these wind turbines look stark against the darkening sky at sunset. The energy of the wind causes the blades to spin, and the energy of the spinning blades is used to generate electricity. People have been using wind for energy for centuries. Until about 200 years ago, for example, ships depended on wind to sail the oceans. And windmills have long been used to gather wind energy to pump water and do other useful work. Today, wind energy is making a comeback. Do you know why? What might be advantages of using the wind for energy? This chapter has the answers. Q: What energy source, now making a comeback, has helped propel ships and pump water for many years? Choices: - weather energy - geothermal energy - solar energy - wind energy A:
Ans: wind energy

Answer the following question given this paragraph: Tornadoes may also come from hurricanes. A hurricane ( Figure below ) is an enormous storm with high winds and heavy rains. Hurricanes may be hundreds of kilometers wide. They may travel for thousands of kilometers. The storm's wind speeds may be greater than 251 kilometers (156 miles) per hour. Hurricanes develop from tropical cyclones. Hurricanes are called typhoons in the Pacific. Q: What are hurricanes called in the pacific? Choices: - tornados - rainstorms - twisters - typhoons A:
(A).
typhoons
Ques:Answer the following question given this paragraph: Darwin proposed the theory of evolution by natural selection. Evolution is a change in the inherited traits of organisms over time. Natural selection is the process by which living things with beneficial traits produce more offspring, so their traits become more common over time. Q: What is the term for a change in the inherited traits of organisms over time? Choices: - mutation - emergence - generation - evolution A:

Ans:evolution
Question: Answer the following question given this paragraph: You must have a GPS receiver to use the system. You can buy many types of these in stores. The GPS receiver detects radio signals from nearby GPS satellites. There are precise clocks on each satellite and in the receiver. The receiver measures the time for radio signals from satellites to reach it. The receiver uses the time and the speed of radio signals to calculate the distance between the receiver and the satellite. The receiver does this with at least four different satellites to locate its position on the Earth's surface ( Figure above ). GPS receivers are now being built into many items, such as cell phones and cars. Q: What do we call the worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations? Choices: - cellular network - radio waves - compass - gps A:
Answer:
gps
