Answer the following question given this paragraph: Specialized structures for reproduction: One example is a fruiting body. Just like a fruit is involved in the reproduction of a fruiting plant, a fruiting body is involved in the reproduction of a fungus. A mushroom is a fruiting body , which is the part of the fungus that produces spores ( Figure below ). The spores are the basic reproductive units of fungi. The mycelium remains hidden until it develops one or more fruiting bodies. Q: Spores are the basic reproductive units of what organism? A:

OPTIONS:
- mushrooms
- yeast
- tropical plants
- fungi

Answer: fungi

Answer the following question given this paragraph: Like roots, the stems of vascular plants are made of dermal, vascular, and ground tissues. Q: In vascular plants, what two basic structures are made of dermal, vascular, and ground tissues? A:

OPTIONS:
- stems and flowers
- roots and seed
- fruits and nuts
- roots and stems

Answer the following question given this paragraph: The surface tension of water is illustrated by a number of common occurrences. For example, water spiders are able to walk across bodies of water because of surface tension. Even though the spiders are denser than water, they do not sink, because the small amount of weight pressing down on the surface is not enough to break the strong hydrogen bonds that hold the surface together. Q: The ability of a water spider to walk across a body of water is an example of what? A:

OPTIONS:
- high density
- low gravity
- magnetism
- surface tension

Answer: surface tension

Answer the following question given this paragraph: Attached to the placenta is the amniotic sac , an enclosed membrane that surrounds and protects the fetus. It contains amniotic fluid , which consists of water and dissolved substances. The fluid allows the fetus to move freely until it grows to fill most of the available space. The fluid also cushions the fetus and helps protect it from injury. Q: What is the enclosed, fluid-filled membrane that surrounds and protects the fetus and is attached to the placenta? A:

OPTIONS:
- epithelial sac
- umbilical sac
- womb
- amniotic sac

Answer:
amniotic sac
