Answer the following question given this paragraph: Plants are multicellular eukaryotes that are placed in the Plant Kingdom . Plant cells have cell walls that are made of cellulose. Plant cells also have chloroplasts. They allow plants to make food by photosynthesis. In addition, plants have specialized reproductive organs that produce gametes. Male reproductive organs produce sperm. Female reproductive organs produce eggs. Male and female reproductive organs may be on the same plant or on different plants. Q: Plant cells have cell walls that are made of what? Choices: - carbonate - nucleus - tissue - cellulose A:
**Answer**
cellulose

Answer the following question given this paragraph: The evolution of vascular tissue revolutionized the plant kingdom. Vascular tissue greatly improved the ability of plants to absorb and transfer water. This allowed plants to grow larger and taller. They could also liver in drier habitats and survive periods of drought. Early vascular plants probably resembled the fern in Figure below . Q: How did a vascular let plants grow? Choices: - they could conduct photosynthesis - they could bear fruit - they could reproduce - they could grow taller A:
**Answer**
they could grow taller

Answer the following question given this paragraph: Wings are an obvious adaptation for flight. They are actually modified front legs. Birds move their wings using muscles in the chest. These muscles are quite large, making up as much as 35 percent of a bird's body weight. Q: In birds, modified front legs are actually what? Choices: - tails - arms - claws - wings A:

Answer the following question given this paragraph: The Antibiotic Crisis The word antibiotic comes from the Greek anti, meaning "against," and bios, meaning "life. " An antibiotic is an organismproduced chemical that is hostile to the growth of other organisms. Today's news and media often address concerns about an antibiotic crisis. Are antibiotics that were used to treat bacterial infections easily treatable in the past becoming obsolete? Are there new "superbugs"bacteria that have evolved to become more resistant to our arsenal of antibiotics? Is this the beginning of the end of antibiotics? All of these questions challenge the healthcare community. One of the main reasons for resistant bacteria is the overuse and incorrect use of antibiotics, such as not completing a full course of prescribed antibiotics. The incorrect use of an antibiotic results in the natural selection of resistant forms of bacteria. The antibiotic kills most of the infecting bacteria, and therefore only the resistant forms remain. These resistant forms reproduce, resulting in an increase in the proportion of resistant forms over non-resistant ones. Another problem is the excessive use of antibiotics in livestock. The routine use of antibiotics in animal feed promotes bacterial resistance as well. In the United States, 70 percent of the antibiotics produced are fed to animals. The antibiotics are not used to prevent disease, but to enhance production of their products. Q: The word antibiotic comes from the greek anti, meaning "against," and bios, meaning this? Choices: - bacteria - germ - virus - life A:
**Answer**
life
