(Q).
Answer the following question given this paragraph: Biological organization exists at all levels in organisms. It can be seen at the smallest level, in the molecules that make up such compounds as DNA and proteins, to the largest level, in an organism such as a blue whale, the largest mammal on Earth. Similarly, single celled prokaryotes and eukaryotes show order in the way their cells are arranged. Single-celled organisms such as an amoeba are free-floating and independent-living. Their single-celled "bodies" are able to carry out all the processes of life such as metabolism and respiration without help from other cells. Q: What is the largest mammal on earth? Choices: - tiger shark - water buffalo - giraffe - blue whale A:
(A).
blue whale
Ques:Answer the following question given this paragraph: Covalent bond energies can be used to estimate the enthalpy changes of chemical reactions. Q: Covalent bond energies can be used to estimate the enthalpy changes of what? Choices: - crystals reactions - Pressure reactions - liquid reactions - chemical reactions A:

Ans:chemical reactions
Answer the following question given this paragraph: Because the molecules of an ideal gas are assumed to have zero volume, the volume available to them for motion is always the same as the volume of the container. In contrast, the molecules of a real gas have small but measurable volumes. At low pressures, the gaseous molecules are relatively far apart, but as the pressure of the gas increases, the intermolecular distances become smaller and smaller (Figure 10.23 "The Effect of Nonzero Volume of Gas Particles on the Behavior of Gases at Low and High Pressures"). As a result, the volume occupied by the molecules becomes significant compared with the volume of the container. Consequently, the total volume occupied by the gas is greater than the volume predicted by the ideal gas law. Thus at very high pressures, the experimentally measured value of PV/nRT is greater than the value predicted by the ideal gas law. Figure 10.23 The Effect of Nonzero Volume of Gas Particles on the Behavior of Gases at Low and High Pressures. Q: What is the volume of the molecules of an ideal gas? Choices: - three - two - one - zero A:
zero
