Q: Answer the following question given this paragraph: Q: Further transformation occurs during organogenesis, the formation of what? Choices: - arteries - muscles - bones - organs A:
A: organs

Q: Answer the following question given this paragraph: Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis ( Figure below ) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. Q: Cellular respiration and photosynthesis are important parts of which cycle? Choices: - vapor cycle - greenhouse effect - water cycle - carbon cycle A:
A: carbon cycle

Q: Answer the following question given this paragraph: Air enters the respiratory system through the nose. As the air passes through the nasal cavity, mucus and hairs trap any particles in the air. The air is also warmed and moistened so it won't harm delicate tissues of the lungs. Q: In the nasal cavity, what 2 things trap particles from incoming air? Choices: - phlegm and hair - saliva and hair - mucus and skin - mucus and hair A:
A: mucus and hair

Q: Answer the following question given this paragraph: 4.2 Prokaryotic Cells Prokaryotes are predominantly single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, and DNA that is not membrane-bound. Most have peptidoglycan cell walls and many have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1 to 5.0 m. As a cell increases in size, its surface area-to-volume ratio decreases. If the cell grows too large, the plasma membrane will not have sufficient surface area to support the rate of diffusion required for the increased volume. Q: As the prokaryotic cell size increases, what happens to its surface area-to-volume ratio? Choices: - stagnates - halts - increases - decreases A:
A: decreases
