Q: Answer the following question given this paragraph: are attached to the end of each bronchiole. At the end of each duct are approximately 100 alveolar sacs, each containing 20 to 30 alveoli that are 200 to 300 microns in diameter. Gas exchange occurs only in alveoli. Alveoli are made of thin-walled parenchymal cells, typically one-cell thick, that look like tiny bubbles within the sacs. Alveoli are in direct contact with capillaries (one-cell thick) of the circulatory system. Such intimate contact ensures that oxygen will diffuse from alveoli into the blood and be distributed to the cells of the body. In addition, the carbon dioxide that was produced by cells as a waste product will diffuse from the blood into alveoli to be exhaled. The anatomical arrangement of capillaries and alveoli emphasizes the structural and functional relationship of the respiratory and circulatory systems. Because there are so many alveoli (~300 million per lung) within each alveolar sac and so many sacs at the end of each alveolar duct, the lungs have a sponge-like consistency. This organization produces a very large surface area that is available for gas exchange. The surface area of alveoli in the lungs is approximately 75 m2. This large surface area, combined with the thin-walled nature of the alveolar parenchymal cells, allows gases to easily diffuse across the cells. Q: The anatomical arrangement of capillaries and alveoli emphasizes the structural and functional relationship of what systems? A:
Answer: respiratory and circulatory

Answer the following question given this paragraph: Sphenodontia Sphenodontia ("wedge tooth") arose in the Mesozoic era and includes only one living genus, Tuatara, comprising two species that are found in New Zealand (Figure 29.26). Tuataras measure up to 80 centimeters and weigh about 1 kilogram. Although quite lizard-like in gross appearance, several unique features of the skull and jaws clearly define them and distinguish the group from the squamates. Q: Sphenodontia sphenodontia ("wedge tooth") arose in the mesozoic era and includes only one of what? A:
****
A: living genus

Answer the following question given this paragraph: Q: Scientists use a quantity called __________ as a measure of disorder, or randomness. A:
OPTIONS:
- chance level
- motion
- vector count
- entropy
entropy

Answer the following question given this paragraph: Alkaliphiles are organisms that "love" bases. Bases are like the opposite of acids. Basic environments where archaeans are found include Mono Lake in California, pictured in Figure below . Mono Lake is the oldest lake in North America. The water is not only unusually basic. It's also saltier than the ocean. So archaeans that live in the water of Mono Lake must have adaptations to both salty and basic conditions. They are haloalkaliphiles. Q: What is the term for organisms that have adaptations to both salty and basic conditions? A:
OPTIONS:
- salinophytes
- sporozoans
- heterophiles
- haloalkaliphiles

Answer: haloalkaliphiles
