Answer the following question given this paragraph: The Calvin cycle occurs in the second stage of photosynthesis. This stage takes place in the stroma of the chloroplast. In the Calvin cycle, carbon dioxide is used to produce glucose (sugar) using the energy stored in ATP and NADPH. The energy is released from these molecules when ATP loses phosphate (P i ) to become ADP and NADPH loses hydrogen (H) to become NADP + . Q: In what stage of photosynthesis does the calvin cycle occur? Choices: - third - fourth - first - second A:
second

Answer the following question given this paragraph: Tectonic plates are large segments of the Earth's crust that move slowly. Suppose that one such plate has an average speed of 4.0 cm/year. (a) What distance does it move in 1 s at this speed? (b) What is its speed in kilometers per million years? 10. (a) Refer to Table 1.3 to determine the average distance between the Earth and the Sun. Then calculate the average speed of the Earth in its orbit in kilometers per second. (b) What is this in meters per second?. Q: What are the large segments of the earth's crust that ordinarily move very slowly? Choices: - ocean plates - lava plates - distinct plates - tectonic plates A:
(Answer)
tectonic plates

Answer the following question given this paragraph: Evolution focuses on past life forms and how they turned into present life forms. The history of life on Earth demonstrates how the first cells formed, turned into simple life forms, and then became more complex plants and animals. The studies of Charles Darwin have reshaped and influenced all aspects of biology. The vast amounts of evidence of evolution demonstrates the importance of the theory of evolution by natural selection. But has this process stopped? Of course not. Evolution does continue today. Q: What theory of evolution is charles darwin most known for? Choices: - natural change - natural variety - immoral selection - natural selection A:
natural selection
