Answer the following question given this paragraph: Anemia is a disease that occurs when there is not enough hemoglobin in the blood to carry oxygen to body cells. Hemoglobin is the blood protein that normally carries oxygen from the lungs to the tissues. Anemia leads to a lack of oxygen in organs. Q: What is the name of the blood protein that carries oxygen from the lungs to the body's assorted tissues? Choices: - insulin - plasma - White Blood cells - hemoglobin A:
hemoglobin

(Answer)
ovary
Ques: 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:
Ans: zero
(Q).
Answer the following question given this paragraph: Coal has different grades. Bituminous coal forms at lower temperatures. It contains a lot of sulfur. When it is burned, it causes a lot of pollution. Anthracite coal forms under higher temperatures. This drives off the sulfur, and the coal burns more cleanly. Q: What type of coal is formed at lower temperatures? Choices: - clean - calcareous - limestones - bituminous A:
(A).
bituminous
Ques:Answer the following question given this paragraph: The symbol represents an electron whose charge corresponds to and since it has no nucleons, . It must be carefully noted that the electron released during beta decay is NOT an orbital electron but an electron whose origin was in the nucleus. The process has one neutron becoming one proton and one electron and the electron being emitted as a beta particle. Since a neutron has been lost AND a proton has been gained, the mass number does not change. The atomic number, however, has increased one due to the gain of a proton. Therefore, as a result of beta decay, the daughter product will have the same mass number as the parent and an atomic number one greater than the parent. Q: The electron released during beta decay is not an orbital electron but an electron whose origin was where? Choices: - outside the nucleus - connected to the nucleus - orbiting the nucleus - in the nucleus A:

Ans:in the nucleus
Answer the following question given this paragraph: Living in a large colony requires good communication. Ants communicate with chemicals called pheromones. For example, an ant deposits pheromones on the ground as it returns to the nest from a food source. It is marking the path so other ants can find the food. Honeybees communicate by doing a "waggle dance. ". Q: Pheromones enable what, which is vital for organisms like ants that live in a large community? Choices: - adaptation - asexual reproduction - migration - communication A:
communication
