Question: Answer the following question given this paragraph: Electromagnetic waves consist of vibrating electric and magnetic fields. They transfer energy across space as well as through matter. Electromagnetic waves vary in their wavelengths and frequencies, and higher-frequency waves have more energy. The full range of wavelengths of electromagnetic waves is called the electromagnetic spectrum. It is outlined in the following Figure below . Q: What kind of waves consist of vibrating electric and magnetic fields? Choices: - gaseous waves - sound waves - hydraulic waves - electromagnetic waves A:
Answer: electromagnetic waves

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

Question: Answer the following question given this paragraph: Q: During karyogamy, the haploid nuclei contributed by the two parents fuse, which produces what? Choices: - mutated cells - arisen cells - cancer cells - diploid cells A:
Answer:
diploid cells
