input: OPTIONS:
- beaks
- bones
- abdomens
- lungs Now, answer this question: Answer the following question given this paragraph: Birds have air sacs that store inhaled air and push it into the lungs like bellows. This keeps the lungs constantly filled with oxygenated air. The lungs also contain millions of tiny passages that create a very large surface area for gas exchange with the blood (see Figure below ). Q: Birds have air sacs that store inhaled air and push it into their what? A:
A:
output: lungs

input: OPTIONS:
- anomalous
- zoology
- superfamily
- phylogeny Now, answer this question: Answer the following question given this paragraph: CHAPTER SUMMARY 20.1 Organizing Life on Earth Scientists continually gain new information that helps understand the evolutionary history of life on Earth. Each group of organisms went through its own evolutionary journey, called its phylogeny. Each organism shares relatedness with others, and based on morphologic and genetic evidence, scientists attempt to map the evolutionary pathways of all life on Earth. Historically, organisms were organized into a taxonomic classification system. However, today many scientists build phylogenetic trees to illustrate evolutionary relationships. Q: Each group of organisms went through its own evolutionary journey, called what? A:
A:
output: phylogeny

input: OPTIONS:
- genomes
- proteins
- iron levels
- alleles Now, answer this question: Answer the following question given this paragraph: Another exception to Mendel's laws is a phenomenon called codominance . For example, our blood type shows codominance. Do you know what your blood type is? Are you A? O? AB? Those letters actually represent alleles. Unlike other traits, your blood type has three alleles, instead of two!. Q: What do the letters in our blood types represent? A:
A:
output:
alleles
