Question: 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:
Answer: infertile

Answer the following question given this paragraph: Water becomes more dense when it is colder and when it has more salt. In the North Atlantic Ocean, cold winds chill the water at the surface. Sea ice grows in this cold water, but ice is created from fresh water. The salt is left behind in the seawater. This cold, salty water is very dense, so it sinks to the bottom of the North Atlantic. Downwelling can take place in other places where surface water becomes very dense (see Figure below ). Q: What is the name for the sinking of the dense, salty seawater in cold climates? Choices: - cyclones - jet stream - tidal activity - downwelling A:
**Answer**
downwelling
