user: Answer the following question given this paragraph:      Q: During karyogamy, the haploid nuclei contributed by the two parents fuse, which produces what?   Choices:  - mutated cells  - arisen cells  - cancer cells  - diploid cells  A:
diploid cells


Answer the following question given this paragraph:   Macroevolution occurs over geologic time above the level of the species. The fossil record reflects this level of evolution. It results from microevolution taking place over many generations.   Q: Microevolution occuring and taking place over many generations results in?   Choices:  - fission  - microinjection  - recalibration  - macroevolution  A:
macroevolution


Q: Answer the following question given this paragraph:   Examples of Power Examples of power are limited only by the imagination, because there are as many types as there are forms of work and energy. (See Table 7.3 for some examples. ) Sunlight reaching Earth’s surface carries a maximum power of about 1.3 kilowatts per square meter (kW/m 2). A tiny fraction of this is retained by Earth over the long term. Our consumption rate of fossil fuels is far greater than the rate at which they are stored, so it is inevitable that they will be depleted. Power implies that energy is transferred, perhaps changing form. It is never possible to change one form completely into another without losing some of it as thermal energy. For example, a 60-W incandescent bulb converts only 5 W of electrical power to light, with 55 W dissipating into thermal energy. Furthermore, the typical electric power plant converts only 35 to 40% of its fuel into electricity. The remainder becomes a huge amount of thermal energy that must be dispersed as heat transfer, as rapidly as it is created. A coal-fired power 6 plant may produce 1000 megawatts; 1 megawatt (MW) is 10 W of electric power. But the power plant consumes chemical energy at a rate of about 2500 MW, creating heat transfer to the surroundings at a rate of 1500 MW. (See Figure 7.25.   Q: What does power imply is happening to energy?   Choices:  - is expanding  - being destroyed  - being created  - being transferred  A:
A: being transferred


Question: Answer the following question given this paragraph:   2.3 Chemical Reactions Chemical reactions, in which chemical bonds are broken and formed, require an initial investment of energy. Kinetic energy, the energy of matter in motion, fuels the collisions of atoms, ions, and molecules that are necessary if their old bonds are to break and new ones to form. All molecules store potential energy, which is released when their bonds are broken. Four forms of energy essential to human functioning are: chemical energy, which is stored and released as chemical bonds are formed and broken; mechanical energy, which directly powers physical activity; radiant energy, emitted as waves such as in sunlight; and electrical energy, the power of moving electrons. Chemical reactions begin with reactants and end with products. Synthesis reactions bond reactants together, a process that requires energy, whereas decomposition reactions break the bonds within a reactant and thereby release energy. In exchange reactions, bonds are both broken and formed, and energy is exchanged. The rate at which chemical reactions occur is influenced by several properties of the reactants: temperature, concentration and pressure, and the presence or absence of a catalyst. An enzyme is a catalytic protein that speeds up chemical reactions in the human body.   Q: What term is used to describe the energy of matter in motion?   Choices:  - frictional energy  - gravitational energy  - emotional energy  - kinetic energy  A:
Answer: kinetic energy


*Question*
Answer the following question given this paragraph:   Fats are one type of lipid. Stored fat gives your body energy to use for later. It’s like having money in a savings account: it’s there in case you need it. Stored fat also cushions and protects internal organs. In addition, it insulates the body. It helps keep you warm in cold weather.   Q: What do stored fats provide our body with for later use?   Choices:  - metals  - hydrogen  - water  - energy  A:
**Answer**
energy


Answer the following question given this paragraph:   High-energy electrons are released from NADH and FADH 2 , and they move along electron transport chains, like those used in photosynthesis. The electron transport chains are on the inner membrane of the mitochondrion. As the high-energy electrons are transported along the chains, some of their energy is captured. This energy is used to pump hydrogen ions (from NADH and FADH 2 ) across the inner membrane, from the matrix into the intermembrane space. Electron transport in a mitochondrion is shown in Figure below .   Q: The electron transport chains are located on the inner membrane of which organelle?   Choices:  - chloroplast  - lysosome  - axon  - mitochondrion  A:


assistant: mitochondrion
