Answer the following question given this paragraph: Ocean water also absorbs gases from the atmosphere. The most important are oxygen and carbon dioxide. Oxygen is needed by living things in the oceans. Much of the carbon dioxide sinks to the bottom of the seas. Carbon dioxide is a major cause of global warming. By absorbing carbon dioxide, the oceans help control global warming. At least as long as the carbon dioxide stays in the seas. Q: Oceans help control global warming by absorbing what? Choices: - hydrogen - ozone - methane - carbon dioxide A:
carbon dioxide

Answer the following question given this paragraph: Potassium Potassium is the major intracellular cation. It helps establish the resting membrane potential in neurons and muscle fibers after membrane depolarization and action potentials. In contrast to sodium, potassium has very little effect on osmotic. Q: What is the major intracellular cation? Choices: - magnesium - sodium - glucose - potassium A:
(Answer)
potassium
Ques: Answer the following question given this paragraph: The rate at which a device changes electric current to another form of energy is called electric power . The SI unit for powerincluding electric poweris the watt. A watt equals 1 joule of energy per second. High wattages are often expressed in kilowatts, where 1 kilowatt equals 1000 watts. The power of an electric device, such as a hair dryer, can be calculated if you know the voltage of the circuit and how much current the device receives. The following equation is used:. Q: What unit of power is equal to 1 joule of energy per second? Choices: - hertz - byte - volt - watt A:
Ans: watt
(Q).
Answer the following question given this paragraph: Water is an example of a common chemical compound. As you can see in the Figure below , each water molecule consists of two atoms of hydrogen and one atom of oxygen. Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition. Q: What molecule consists of two atoms of hydrogen and one atom of oxygen? Choices: - carbon monoxide - hydrogen peroxide - air - water A:
(A).
water
Ques:Answer the following question given this paragraph: 6.2 The Cell Cycle The cell cycle is an orderly sequence of events. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages. In eukaryotes, the cell cycle consists of a long preparatory period, called interphase. Interphase is divided into G1, S, and G2 phases. Mitosis consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis is usually accompanied by cytokinesis, during which the cytoplasmic components of the daughter cells are separated either by an actin ring (animal cells) or by cell plate formation (plant cells). Each step of the cell cycle is monitored by internal controls called checkpoints. There are three major checkpoints in the cell cycle: one near the end of G1, a second at the G2M transition, and the third during metaphase. Q: What consists of these five stages: prophase, prometaphase, metaphase, anaphase, and telophase? Choices: - evolution - germination - meiosis - mitosis A:

Ans:mitosis
Ques: Answer the following question given this paragraph: Formed when elements either gain or lose electrons. Q: What is the most important factor determining soil type? Choices: - landscape - plant life - ecology - climate A:
Ans:
