Answer the following question given this paragraph: The concentration of hydronium ions in a solution is known as acidity . In pure water, the concentration of hydronium ions is very low; only about 1 in 10 million water molecules naturally breaks down to form a hydronium ion. As a result, pure water is essentially neutral. Acidity is measured on a scale called pH , as shown in Figure below . Pure water has a pH of 7, so the point of neutrality on the pH scale is 7. Q: The concentration of hydronium ions in a solution is known as what? Choices: - base - akaline - pH value - acidity A:
acidity
Answer the following question given this paragraph: Transport vesicles are able to move molecules between locations inside the cell. For example, transport vesicles move proteins from the rough endoplasmic reticulum to the Golgi apparatus. Q: What cellular structure moves molecules between locations inside the cell? Choices: - transport vessels - capillaries - dna vesicles - transport vesicles A:
transport vesicles
Q: Answer the following question given this paragraph: Jupiter has lots of moons. As of 2012, we have discovered over 66 natural satellites of Jupiter. Four are big enough and bright enough to be seen from Earth using a pair of binoculars. These four moons were first discovered by Galileo in 1610. They are called the Galilean moons . The figure below shows the four Galilean moons and their sizes relative to each other ( Figure below ). These moons are named Io, Europa, Ganymede, and Callisto. The Galilean moons are larger than even the biggest dwarf planets, Pluto and Eris. Ganymede is the biggest moon in the solar system. It is even larger than the planet Mercury!. Q: The four moons of jupiter are collectively named after what 17th century astronomer, who discovered them? Choices: - Linnaeus - copernicus - darwin - galileo A:
A: galileo
Question: Answer the following question given this paragraph: Unlike corals, jellyfish spend most of their lives as medusae. They live virtually everywhere in the ocean. They are typically carnivores. They prey on zooplankton, other invertebrates, and the eggs and larvae of fish. Q: Unlike corals, jellyfish spend most of their lives as what? Choices: - infants - pupae - cercariae - medusae A:
Answer: medusae
*Question*
Answer the following question given this paragraph: Energy in a body of water can be gained or lost depending on conditions. When water is heated above a certain temperature steam is generated. The increase in heat energy creates a higher level of disorder in the water molecules as they boil off and leave the liquid. Q: What do you need to do to water to make it steam? Choices: - freeze it - stir it - cool it - heat it A:
**Answer**
heat it
Answer the following question given this paragraph: At certain times of year, a stream or river may overflow its banks. The area of land that is flooded is called the floodplain. The floodplain may be very wide where the river flows over a nearly flat surface. Q: At certain times of year, a stream or river may overflow its banks. what is the area of land that is flooded called? Choices: - inlet - run off - lowland - floodplain A:
floodplain
