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? Choices: - microvilli - tentacles - sporangia - flagella A:
flagella
(Question)
Answer the following question given this paragraph: The axes of rotation of the planets are mostly nearly perpendicular to the orbital plane. Q: How do planets usually rotate to their orbital planes? Choices: - exactly perpendicular - chaotic - randomly - nearly perpendicular A:
(Answer)
nearly perpendicular
Ques: Answer the following question given this paragraph: Digestion includes both mechanical and chemical processes. Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with. Q: Which form of digestion is a purely physical process that does not change the chemical nature of the food? Choices: - slow - simple - electromagnetic - mechanical A:
Ans: mechanical
(Q).

(A).
fossil records
Ques:Answer the following question given this paragraph: ART CONNECTION QUESTIONS 1. Figure 14.10 In eukaryotic cells, DNA and RNA synthesis occur in a separate compartment from protein synthesis. In prokaryotic cells, both processes occur together. What advantages might there be to separating the processes? What advantages might there be to having them occur together? 2. Figure 14.14 You isolate a cell strain in which the joining together of Okazaki fragments is impaired and. Q: Unlike eukaryotic cells, dna and rna synthesis in prokaryotic cells occurs together with synthesis of what? Choices: - membrane - fruit - mutation - protein A:

Ans:protein
Ques: Answer the following question given this paragraph: Decomposers release nutrients when they break down dead organisms. Q: What do decomposers release when they break down dead organisms? Choices: - methane - carbon dioxide - acids - nutrients A:
Ans:
