Q: What element is all life built around? Read this paragraph and choose the correct option from the provided answers: The cell is the basic unit of life. A cell is made of molecules, which are made of elements. All life-which means all bacteria and archaea, all protists, fungi, plants and animals-is built around the element carbon, and four categories of organic compounds: carbohydrates, lipids, proteins, and nucleic acids. These molecules come together to form a cell, which is the basis of life. One particular type of protein, enzymes, are biological catalysts, allowing biochemical reactions to proceed at the rate necessary to maintain life. One other molecule, water, is also essential to life, though water is not an organic compound. Choices: - hydrogen - neon - oxygen - carbon A:
(Answer)
carbon

Ques: Q: Located above the stratosphere, what layer is the place where meteors burn up? Read this paragraph and choose the correct option from the provided answers: The mesosphere is the layer above the stratosphere. Temperature decreases with altitude in this layer. Meteors burn up here. Choices: - unisphere - troposphere - atmosphere - mesosphere A:
Ans: mesosphere

(Q).
Q: A geiger counter is used for detecting what? Read this paragraph and choose the correct option from the provided answers: One of the simplest ways of detecting radioactivity is by using a piece of photographic film embedded in a badge or a pen. On a regular basis, the film is developed and checked for exposure. Comparing the exposure level of the film with a set of standard exposures indicates the amount of radiation a person was exposed to. Another means of detecting radioactivity is an electrical device called a Geiger counter (Figure 15.2 "Detecting Radioactivity"). It contains a gas-filled chamber with a thin membrane on one end that allows radiation emitted from radioactive nuclei to enter the chamber and knock electrons off atoms of gas (usually argon). The presence of electrons and positively charged ions causes a small current, which is detected by the Geiger counter and converted to a signal on a meter or, commonly, an audio circuit to produce an audible "click. Choices: - mutation - pressure - convection - radiation A:
(A).
radiation

Ques:Q: What do fish eggs hatch to form? Read this paragraph and choose the correct option from the provided answers: Almost all fish have sexual reproduction, generally with separate sexes. Most fish are oviparous. Many species reproduce by spawning. Eggs hatch to form larvae, which undergo metamorphosis to become adults. Choices: - adolescent fish - tadpoles - unfertilized eggs - fish eggs hatch to form larvae A:

Ans:fish eggs hatch to form larvae

Q: An electric current flows in a path called what? Read this paragraph and choose the correct option from the provided answers: Electricity refers to a number of phenomena associated with the presence and flow of electric charge. Electricity includes such diverse things as lightning, static electricity, the current generated by a battery as it discharges, and many other influences on our daily lives. The flow or movement of charge is an electric current (Figure 17.2). Electrons or ions may carry the charge. The elementary unit of charge is the charge of a proton, which is equal in magnitude to the charge of an electron. The SI unit of charge is the coulomb (C) and the charge of a proton is 1.602 1019 C. The presence of an electric charge generates an electric field. Electric current is the rate of flow of charge. The SI unit for electrical current is the SI base unit called the ampere (A), which is a flow rate of 1 coulomb of charge per second (1 A = 1 C/s). An electric current flows in a path, called an electric circuit. In most chemical systems, it is necessary to maintain a closed path for current to flow. The flow of charge is generated by an electrical potential difference, or potential, between two points in the circuit. Electrical potential is the ability of the electric field to do work on the charge. The SI unit of electrical potential is the volt (V). When 1 coulomb of charge moves through a potential difference of 1 volt, it gains or loses 1 joule (J) of energy. Table 17.1 summarizes some of this information about electricity. Common Electrical Terms Quantity. Choices: - electric ring - electric course - fuse - electric circuit A:
