Answer the following question given this paragraph: Plants have eukaryotic cells with large central vacuoles, cell walls containing cellulose, and plastids such as chloroplasts and chromoplasts. Different types of plant cells include parenchymal, collenchymal, and sclerenchymal cells. The three types differ in structure and function. Q: What living things have cell walls containing cellulose and plastids such as chloroplasts? Choices: - reptiles - mammals - animals - plants A:
plants
Q: Answer the following question given this paragraph: All reptiles have a cloaca , a single exit and entrance for sperm, eggs, and waste, located at the base of the tail. Most reptiles lay amniotic eggs covered with leathery or hard shell. These eggs can be placed anywhere as they don't have to be in a moist environment, like the eggs of amphibians. However, not all species lay eggs, as certain species of squamates can give birth to live young. Q: Most reptiles lay what kind of eggs? Choices: - hard-shelled - umbilical - roe - amniotic A:
A: amniotic
Question: Answer the following question given this paragraph: has a single main root that grows down. A fibrous root system forms a dense network of roots that is closer to the soil surface. An example of a tap root system is a carrot. Grasses such as wheat, rice, and corn are examples of fibrous root systems. Fibrous root systems are found in monocots; tap root systems are found in dicots. 37 Monocots have leaves with parallel venation, and dicots have leaves with reticulate, net-like venation. 39 The process of bulk flow moves water up the xylem and moves photosynthates (solutes) up and down the phloem. 41 Gravitropism will allow roots to dig deep into the soil to find water and minerals, whereas the seedling will grow towards light to enable photosynthesis. 43 To prevent further entry of pathogens, stomata close, even if they restrict entry of CO2. Some pathogens secrete virulence factors that inhibit the closing of stomata. Abscisic acid is the stress hormone responsible for inducing closing of stomata. Q: Grasses such as wheat, rice, and corn are examples of fibrous root systems. fibrous root systems are found in monocots; tap root systems are found in these? Choices: - mosses - monocots - gymnosperms - dicots A:
Answer: dicots

Answer the following question given this paragraph: The magnetic field produced by a current in a wire moves around the wire in concentric circles. More current creates a stronger magnetic field, and the direction of the current determines the direction of the magnetic field. Q: How does the magnetic field produced by a current in a wire move? Choices: - intermittently - slowly - counterclockwise - in concentric circles A:
**Answer**
in concentric circles
