Answer the following question given this paragraph: The cells of all protists have a nucleus. They also have other membrane-bound organelles. For example, all of them have mitochondria, and some of them have chloroplasts. Q: The cells of all protists have a what? Choices: - argon - cell walls - protons - nucleus A:
nucleus

Answer the following question given this paragraph: n = cv , where v is the observed speed of light in the material. Since the speed of light is always less than only in a vacuum, the index of refraction is always greater than or equal to one. Q: The constant "c" can be specifically used to represent the (extremely fast) speed of what? Choices: - electricity - sound - gravity - light A:
(Answer)
light
Ques: Answer the following question given this paragraph: DNA technology has proved very beneficial to humans. Transgenic animals are animals that have incorporated a gene from another species into their genome. They are used as experimental models to perform phenotypic tests with genes whose function is unknown, or to generate animals that are susceptible to certain compounds or stresses for testing purposes. Other applications include the production of human hormones, such as insulin. Many times these animals are rodents, such as mice, or fruit flies ( Drosophila melanogaster ). Fruit flies are extremely useful as genetic models to study the effects of genetic changes on development. GloFish are the first genetically modified animal to be sold as a pet and are transgenic zebrafish transfected with a natural fluorescence gene. Watch these fish at http://www. youtube. com/watch?v=6cQLGKH2ojY or in the video below. Q: Transgenic animals are animals that have incorporated a gene from another species into their what? Choices: - enemies - food - habitats - genome A:
Ans: genome

Answer the following question given this paragraph: A coefficient is a small whole number placed in front of a formula in an equation in order to balance it. The 2 in front of the H 2 means that there are a total of atoms of hydrogen as reactants. Visually, the reaction looks like the Figure below . Q: What do you call a small whole number placed in front of a formula in an equation in order to balance it? Choices: - correlation - divisible - function - coefficient A:
(A).
coefficient
Ques:Answer the following question given this paragraph: Calorimetry is the measurement of the transfer of heat into or out of a system during a chemical reaction or physical process. A calorimeter is an insulated container that is used to measure heat changes. The majority of reactions that can be analyzed in a calorimetry experiment are either liquids or aqueous solutions. A frequently used and inexpensive calorimeter is a set of nested foam cups fitted with a lid to limit the heat exchange between the liquid in the cup and the air in the surroundings (see Figure below ). In a typical calorimetry experiment, specific volumes of the reactants are dispensed into separate containers and the temperature of each is measured. They are then mixed into the calorimeter, which starts the reaction. The reactant mixture is stirred until the reaction is complete, while the temperature of the reaction is continuously monitored. Q: What kind of container is used to measure heat changes during a chemical reaction or physical process? Choices: - hydrostatic - thermal flask - graduated cylinder - calorimeter A:

Ans:calorimeter
Answer the following question given this paragraph: For most of a star's life, hydrogen atoms fuse to form helium atoms. A star like this is a main sequence star . The hotter a main sequence star is, the brighter it is. A star remains on the main sequence as long as it is fusing hydrogen to form helium. Q: For most of a star's life, hydrogen atoms fuse to form what? Choices: - neon atoms - ionic atoms - gas atoms - helium atoms A:
helium atoms
