Answer the following question given this paragraph: An electrolytic cell is the apparatus used for carrying out an electrolysis reaction. In an electrolytic cell, electric current is applied to provide a source of electrons for driving the reaction in a nonspontaneous direction. In a voltaic cell, the reaction goes in a direction that releases electrons spontaneously. In an electrolytic cell, the input of electrons from an external source forces the reaction to go in the opposite direction. Q: What is the apparatus used for carrying out an electrolysis reaction? Choices: - Golgi apparatus - catalyst - an aqueous cell - an electrolytic cell A:
(Answer)
an electrolytic cell
Ques: Answer the following question given this paragraph: Most ocean waves are caused by winds. The size of a wave depends on how fast, how far, and how long the wind blows. Tsunamis are waves caused by earthquakes. Q: What is the cause of most ocean waves? Choices: - tides - Magnetic pull - Gravity - winds A:
Ans: winds
(Q).
Answer the following question given this paragraph: Rising air currents carry water vapor into the atmosphere. As the water vapor rises in the atmosphere, it cools and condenses. Condensation is the process in which water vapor changes to tiny droplets of liquid water. The water droplets may form clouds. If the droplets get big enough, they fall as precipitation rain, snow, sleet, hail, or freezing rain. Most precipitation falls into the ocean. Eventually, this water evaporates again and repeats the water cycle. Some frozen precipitation becomes part of ice caps and glaciers. These masses of ice can store frozen water for hundreds of years or longer. Q: Rising air currents carry water vapor into what? Choices: - stratosphere - ionosphere - troposphere - atmosphere A:
(A).
atmosphere
Ques:Answer the following question given this paragraph: Annelids are segmented worms such as earthworms and leeches. Annelids have a coelom, closed circulatory system, excretory system, and complete digestive system. They also have a brain. Earthworms are important deposit feeders that help form and enrich soil. Leeches are either predators or parasites. Parasitic leeches feed off the blood of vertebrate hosts. Q: Parasitic leeches feed off of what? Choices: - brain - tissue - tumor - blood A:

Ans:blood
Answer the following question given this paragraph: Metalloids are the smallest class of elements, containing just six elements. They fall between metals and nonmetals in the periodic table. Q: What is the smallest class of elements? Choices: - halogens - noble gases - synthetics - metalloids A:
metalloids
