Answer the following question given this paragraph: Frogs The frog order also includes toads. Unlike other amphibians, frogs and toads lack a tail by adulthood. Their back legs are also longer because they are specialized for jumping. Frogs can jump as far as 20 times their body length. That's like you jumping more than the length of a basketball court! red-eyed tree frog. Q: Frogs and toads have long back legs which are specialized for what action? Choices: - flying - swimming - sprinting - jumping A:
jumping

Answer the following question given this paragraph: To measure very small masses, scientists use electronic balances, like the one in the Figure below . This type of balance also makes it easier to make accurate measurements because mass is shown as a digital readout. In the picture, the balance is being used to measure the mass of a white powder on a plastic weighing tray. The mass of the tray alone would have to be measured first and then subtracted from the mass of the tray and powder together. The difference between the two masses is the mass of the powder alone. Q: What instrument, with a digital readout, is used by scientists to measure very small masses? Choices: - mixed balance - mechanical balance - common balance - electronic balance A:
**Answer**
electronic balance

Answer the following question given this paragraph: A laboratory instrument used to analyze and test for static charge is called an electroscope. Seen below, an electroscope consists of a metal knob connected by a metal stem to two very lightweight pieces of metal called leaves, shown in yellow. The leaves are enclosed in a box to eliminate stray air currents. Q: What laboratory instrument is used to analyze and test for static charge? Choices: - microscope - bunsen burner - microtome - electroscope A:
(Answer)
electroscope
