Ques:Q: Mammalian lungs are located in what cavity, where they are surrounded and protected by the rib cage, intercostal muscles, and chest wall? Read this paragraph and choose the correct option from the provided answers: 39.3 | Breathing By the end of this section, you will be able to: Describe how the structures of the lungs and thoracic cavity control the mechanics of breathing Explain the importance of compliance and resistance in the lungs Discuss problems that may arise due to a V/Q mismatch Mammalian lungs are located in the thoracic cavity where they are surrounded and protected by the rib cage, intercostal muscles, and bound by the chest wall. The bottom of the lungs is contained by the diaphragm, a skeletal muscle that facilitates breathing. Breathing requires the coordination of the lungs, the chest wall, and most importantly, the diaphragm. Choices: - ventral - abdominopelvic - dorsal - thoracic A:

Ques:Q: What is the process of larva becoming an adult called? Read this paragraph and choose the correct option from the provided answers: After hatching, most arthropods go through one or more larval stages before reaching adulthood. The larvae may look very different from the adults. They change into the adult form in a process called metamorphosis. During metamorphosis, the arthropod is called a pupa. It may or may not spend this stage inside a special container called a cocoon. A familiar example of arthropod metamorphosis is the transformation of a caterpillar (larva) into a butterfly (adult) (see Figure below ). Distinctive life stages and metamorphosis are highly adaptive. They allow functions to be divided among different life stages. Each life stage can evolve adaptations to suit it for its specific functions without affecting the adaptations of the other stages. Choices: - parthenogenesis - synthesis - evolution - metamorphosis A:

Ans:metamorphosis

Ques:Q: What is the organic material that comes from plants and animals that were recently living called? Read this paragraph and choose the correct option from the provided answers: Biomass is the material that comes from plants and animals that were recently living. Biomass can be burned directly. This happens when you burn a log in your fireplace. For as long as humans have had fire, people have used biomass for heating and cooking. Choices: - biofuels - contaminants - chlorophyll - biomass A:

Ans:biomass
