Ques:Answer the following question given this paragraph: The amount of charge, , held by each plate is given by where again is the voltage difference between the plates and is the capacitance of the plate configuration. Capacitance can be thought of as the capacity a device has for storing charge . In the parallel plate case the capacitance is given by where is the area of the plates, is the distance between the plates, and is the permittivity of free space whose value is . Q: What can be thought of as the capacity a device has for storing charge? Choices: - potential - velocity - resonance - capacitance A:

Ans:capacitance

Ques:Answer the following question given this paragraph: A ribosome is a small organelle where proteins are made. It's like a factory in the cell. It gathers amino acids and joins them together into proteins. Unlike other organelles, the ribosome is not surrounded by a membrane. As a result, some scientists do not classify it as an organelle. Ribosomes may be found floating in the cytoplasm. Some ribosomes are located on the surface of another organelle, the endoplasmic reticulum. Q: What is the term for a small organelle where proteins are made? Choices: - atom - capsule - ovary - ribosome A:

Ans:ribosome

Ques:Answer the following question given this paragraph: A vapor light also produces visible light by electroluminescence The bulb contains a small amount of solid sodium or mercury as well as a mixture of neon and argon gases. When an electric current passes through the gases, it causes the solid sodium or mercury to change to a gas and emit visible light. Sodium vapor lights, like the streetlight pictured in the Figure below , produce yellowish light. Mercury vapor lights produce bluish light. In addition to lighting city streets, vapor lights are used to light highways and stadiums. The bulbs are very bright and long lasting so they are a good choice for these places. Q: When electricity is passed through solid sodium it changes into what and gives off light? Choices: - plasma - liquids - hydrocarbons - gas A:

Ans:gas

Ques:Answer the following question given this paragraph: The genetic code works as a series of three-letter codes. Each sequence of three letters, called a triplet, corresponds to one of the twenty common amino acids. The triplets are read by the cell, one after the other, in the process of protein synthesis. The Table below shows all of the possible triplets and the amino acids that result from each three-letter code. Q: In what kind of a series does the genetic code work? Choices: - nine letter-codes - universal codes - four-letter codes - three-letter codes A:

Ans:
three-letter codes
