Problem: OPTIONS:
- gaseous waves
- sound waves
- hydraulic waves
- electromagnetic waves
Q: 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?   A:
Answer: electromagnetic waves

Problem:OPTIONS:

Answer the following question given this paragraph:   24.2 Classifications of Fungi Chytridiomycota (chytrids) are considered the most primitive group of fungi. They are mostly aquatic, and their gametes are the only fungal cells known to have flagella. They reproduce both sexually and asexually; the asexual spores are called zoospores. Zygomycota (conjugated fungi) produce non-septated hyphae with many nuclei. Their hyphae fuse during sexual reproduction to produce a zygospore in a zygosporangium. Ascomycota (sac fungi) form spores in sacs called asci during sexual reproduction. Asexual reproduction is their most common form of reproduction. Basidiomycota (club fungi) produce showy fruiting bodies that contain basidia in the form of clubs. Spores are stored in the basidia. Most familiar mushrooms belong to this division. Fungi that have no known sexual cycle were classified in the form phylum Deuteromycota, which the present classification puts in the phyla Ascomycota and Basidiomycota. Glomeromycota form tight associations (called mycorrhizae) with the roots of plants.   Q: Chytridiomycota are considered the most primitive of what kingdom?   A:
OPTIONS:
- animals
- plants
- protists
- fungi

Answer: fungi

Question: Answer the following question given this paragraph:   When energy is released in a chemical reaction or process, that energy is expressed as a negative number. Figure below shows electron affinities in kJ/mol for the main group elements.   Q: How is energy expressed when it is released in a chemical reaction?   A:
OPTIONS:
- as an equation
- as a percentage
- as a positive number
- as negative number
Answer: as negative number

input: OPTIONS:
- microvilli
- tentacles
- sporangia
- flagella Now, answer this question: Answer the following question given this paragraph:   Flagella ( flagellum , singular) are long, thin structures that protrude from the cell membrane. Both eukaryotic and prokaryotic cells can have flagella. Flagella help single-celled organisms move or swim towards food. The flagella of eukaryotic cells are normally used for movement too, such as in the movement of sperm cells, which have only a single flagellum. The flagella of either group are very different from each other. Prokaryotic flagella, shown in Figure below , are spiral-shaped and stiff. They spin around in a fixed base much like a screw does, which moves the cell in a tumbling fashion. Eukaryotic flagella are made of microtubules that bend and flex like a whip.   Q: What are the long, thin structures that protrude from the cell membrane and help single-celled organisms move or swim towards food?   A:
A:
output:
flagella
