Answer the following question given this paragraph: Although flowers and their components are the major innovations of angiosperms, they are not the only ones. Angiosperms also have more efficient vascular tissues. Additionally, in many flowering plants the ovaries ripen into fruits. Fruits are often brightly colored, so animals are likely to see and eat them and disperse their seeds (see Figure below ). Q: Fruit comes from the ovaries of what types of plants? Choices: - deciduous - perennial - sprouting - flowering A:
flowering
Answer the following question given this paragraph: Protein Structure. Primary protein structure is the sequence of amino acids in a single polypeptide. Secondary protein structure refers to internal shapes, such as alpha helices and beta pleated sheets, that a single polypeptide takes on due to bonds between atoms in different parts of the polypeptide. Tertiary protein structure is the overall three-dimensional shape of a protein consisting of one polypeptide. Quaternary protein structure is the shape of a protein consisting of two or more polypeptides. For a brief animation of protein structure, see www. stolaf. edu/people/giannini/flashanimat/proteins/protein%20structure. swf . Q: A sequence of amino acids in single polypeptide is the primary structure for what? Choices: - lipids - cells - dna - proteins A:
proteins
Q: Answer the following question given this paragraph: Gymnosperms are seed plants that produce naked seeds in cones. There are about 1000 species of gymnosperms. Conifers are the most common group of gymnosperms. The spruce tree in Figure below is an example of a conifer. Q: What are seeds plants that produce naked seeds in cones called? Choices: - cytoplasm - lipids - angiosperms - gymnosperms A:
A: gymnosperms
Question: Answer the following question given this paragraph: The force that a magnet exerts on certain materials, including other magnets, is called magnetic force . The force is exerted over a distance and includes forces of attraction and repulsion. North and south poles of two magnets attract each other, while two north poles or two south poles repel each other. A magnet can exert force over a distance because the magnet is surrounded by a magnetic field . In the Figure below , you can see the magnetic field surrounding a bar magnet. Tiny bits of iron, called iron filings, were placed under a sheet of glass. When the magnet was placed on the glass, it attracted the iron filings. The pattern of the iron filings shows the lines of force that make up the magnetic field of the magnet. The concentration of iron filings near the poles indicates that these areas exert the strongest force. You can also see how the magnetic field affects the compasses placed above the magnet.

Q: The force that a magnet exerts on certain materials is called what? Choices: - stellar force - velocity force - centripetal force - magnetic force A:
Answer: magnetic force

Q: Answer the following question given this paragraph: Slime Molds A subset of the amoebozoans, the slime molds, has several morphological similarities to fungi that are thought to be the result of convergent evolution. For instance, during times of stress, some slime molds develop into spore-generating fruiting bodies, much like fungi. The slime molds are categorized on the basis of their life cycles into plasmodial or cellular types. Plasmodial slime molds are composed of large, multinucleate cells and move along surfaces like an amorphous blob of slime during their feeding stage (Figure 23.27). Food particles are lifted and engulfed into the slime mold as it glides along. Upon maturation, the plasmodium takes on a net-like appearance with the ability to form fruiting bodies, or sporangia, during times of stress. Haploid spores are produced by meiosis within the sporangia, and spores can be disseminated through the air or water to potentially land in more favorable environments. If this occurs, the spores germinate to form ameboid or flagellate haploid cells that can combine with each other and produce a diploid zygotic slime mold to complete the life cycle. Q: Slime molds have several morphological similarities to fungi, including spore-generation, that are thought to be the result of convergent what? Choices: - generation - phenomenon - emergence - evolution A:
A: evolution
