Answer the following question given this paragraph: In other cases, individuals may appear similar although they are not members of the same species. For example, even though bald eagles (Haliaeetus leucocephalus) and African fish eagles (Haliaeetus vocifer) are both birds and eagles, each belongs to a separate species group (Figure 18.10). If humans were to artificially intervene and fertilize the egg of a bald eagle with the sperm of an African fish eagle and a chick did hatch, that offspring, called a hybrid (a cross between two species), would probably be infertileunable to successfully reproduce after it reached maturity. Different species may have different genes that are active in development; therefore, it may not be possible to develop a viable offspring with two different sets of directions. Thus, even though hybridization may take place, the two species still remain separate. Q: If humans were to artificially intervene and fertilize the egg of a bald eagle with the sperm of an african fish eagle and a chick did hatch, that offspring, called a hybrid (a cross between two species), would probably be this? Choices: - fertile - nonviable - mutated - infertile A:
infertile
Answer the following question given this paragraph: Sodium and chloride ions have equal but opposite charges. Opposite electric charges attract each other, so sodium and chloride ions cling together in a strong ionic bond. You can see this in row 2 of the Figure above . (Brackets separate the ions in the diagram to show that the ions in the compound do not actually share electrons. ) When ionic bonds hold ions together, they form an ionic compound. The compound formed from sodium and chloride ions is named sodium chloride. It is commonly called table salt. You can see an animation of sodium chloride forming at this URL: http://www. visionlearning. com/library/module_viewer. php?mid=55. Q: Sodium and chloride ions have equal but what charges? Choices: - path - positive - simple - opposite A:
opposite

Answer the following question given this paragraph: Sometimes two different minerals have the same chemical composition. But they are different minerals because they have different crystal structures. Diamonds are very valuable as gemstones because they are very pretty and very hard. Graphite is the "lead" in pencils. It's not hard at all! Amazingly, both are made just of carbon. Compare the diamond with the pencil lead ( Figure below ). Why are they so different? The carbon atoms in graphite bond to form layers. The bonds between each layer are weak. The carbon sheets can just slip past each other. The carbon atoms in diamonds bond together in all three directions. This strong network makes diamonds very hard. Q: Why are two different minerals considered different though they have the same chemical composition? Choices: - different linear structures - different molecular structures - different rods structures - different crystal structures A:
**Answer**
different crystal structures
