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

Ques:Answer the following question given this paragraph: There are only about 1,000 living species of gymnosperms, whereas there are hundreds of thousands of living species of angiosperms. Because angiosperms are so numerous and diverse, they are described separately below. Living gymnosperms are typically classified in the divisions described in Table below . Most modern gymnosperms are trees with woody trunks. The majority are conifers such as pine trees. Q: Conifers are the most prevalent type of what plant group? Choices: - theropods - algae - angiosperms - gymnosperms A:

Ans:gymnosperms

Ques:Answer the following question given this paragraph: You can see the structural formula of glucose and two other sugars in Figure below . The other sugars in the figure are fructose and sucrose. Fructose is an isomer of glucose. It is found in fruits. It has the same atoms as glucose, but they are arranged differently. Sucrose is table sugar. It consists of one molecule of glucose and one molecule of fructose. Q: Sucrose consists of one molecule of glucose and one molecule of what else? Choices: - protein - lactose - alcohol - fructose A:

Ans:fructose

Ques:Answer the following question given this paragraph: Gap genes themselves are under the effect of maternal effect genes, such as bicoid and nanos. Gap genes also regulate each other to achieve their precise striped expression patterns. The maternal effect is when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype. This often occurs when the mother supplies mRNA or proteins to the egg, affecting early development. In developing Drosophila, maternal effects include axis determination. Q: What is the term for when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype? Choices: - congenital effect - uterine effect - oceanic effect - maternal effect A:

Ans:
maternal effect
