Q: Answer the following question given this paragraph: Weeks 47 Respiratory development in the embryo begins around week 4. Ectodermal tissue from the anterior head region invaginates posteriorly to form olfactory pits, which fuse with endodermal tissue of the developing pharynx. An olfactory pit is one of a pair of structures that will enlarge to become the nasal cavity. At about this same time, the lung bud forms. The lung bud is a dome-shaped structure composed of tissue that bulges from the foregut. The foregut is endoderm just inferior to the pharyngeal pouches. The laryngotracheal bud is a structure that forms from the longitudinal extension of the lung bud as development progresses. The portion of this structure nearest the pharynx becomes the trachea, whereas the distal end becomes more bulbous, forming bronchial buds. A bronchial bud is one of a pair of structures that will eventually become the bronchi and all other lower respiratory structures (Figure 22.29). Q: Respiratory development in the embryo begins around week 4. ectodermal tissue from the anterior head region invaginates posteriorly to form olfactory pits, which fuse with endodermal tissue of the developing pharynx. an olfactory pit is one of a pair of structures that will enlarge to become this? A:
Answer: nasal cavity

Answer the following question given this paragraph: A certain mineral may form in different colors. Figure below shows four samples of quartz, including one that is colorless and one that is purple. The purple color comes from a tiny amount of iron. The iron in quartz is a chemical impurity. Iron is not normally found in quartz. Many minerals are colored by chemical impurities. Other factors can also affect a mineral's color. Weathering changes the surface of a mineral. Because color alone is unreliable, geologists rarely identify a mineral just on its color. To identify most minerals, they use several properties. Q: Where does the purple color in quartz come from? A:
****
A: iron

Answer the following question given this paragraph: Bees are beautiful creatures that help plants flourish. They carry pollen from one plant to another to facilitate plant growth and development. But, they can also be troublesome when they sting you. For people who are allergic to bee venom, this can be a serious, life-threatening problem. For the rest of us, it can be a painful experience. When stung by a bee, one first-aid treatment is to apply a paste of baking soda (sodium bicarbonate) to the stung area. This weak base helps with the itching and swelling that accompanies the bee sting. Q: What do bees carry from one plant to another to facilitate plant growth and development? A:
OPTIONS:
- nutrients
- spores
- fungi
- pollen
pollen

Answer the following question given this paragraph: Pulmonary circulation is the part of the circulatory system that carries blood between the heart and lungs (the term pulmonary means "of the lungs"). It is illustrated in Figure below . Deoxygenated blood leaves the right ventricle through pulmonary arteries, which transport it to the lungs. In the lungs, the blood gives up carbon dioxide and picks up oxygen. The oxygenated blood then returns to the left atrium of the heart through pulmonary veins. Q: While in the lungs, blood gives up carbon dioxide and picks up what element before returning to the heart? A:
OPTIONS:
- nitrogen
- methane
- hydrogen
- oxygen

Answer: oxygen

Question: Answer the following question given this paragraph: Magma that cools underground forms intrusions ( Figure below ). Intrusions become land formations if they are exposed at the surface by erosion. Q: What does magma that cools underground form? A:
OPTIONS:
- chambers
- new crust
- fluctuations
- instrusions
Answer: instrusions

input: OPTIONS:
