Q: Answer the following question given this paragraph: The walls of the ventricle are lined with trabeculae carneae, ridges of cardiac muscle covered by endocardium. In addition to these muscular ridges, a band of cardiac muscle, also covered by endocardium, known as the moderator band (see Figure 19.9) reinforces the thin walls of the right ventricle and plays a crucial role in cardiac conduction. It arises from the inferior portion of the interventricular septum and crosses the interior space of the right ventricle to connect with the inferior papillary muscle. When the right ventricle contracts, it ejects blood into the pulmonary trunk, which branches into the left and right pulmonary arteries that carry it to each lung. The superior surface of the right ventricle begins to taper as it approaches the pulmonary trunk. At the base of the pulmonary trunk is the pulmonary semilunar valve that prevents backflow from the pulmonary trunk. Q: What reinforces the thin walls of the right ventricle and plays a crucial role in cardiac conduction? Choices: - pores band - moderator valve - pores valve - moderator band A:
A: moderator band

Q: Answer the following question given this paragraph: In seed plants, the gametophyte generation takes place in a cone or flower, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule. Pollination must occur for fertilization to take place. Zygotes develop into embryos inside seeds, from which the next sporophyte generation grows. Q: What develops into embryos inside seeds, from which the next sporophyte generation grows? Choices: - secretions - buds - pupa - zygotes A:
A: zygotes

Q: Answer the following question given this paragraph: Mendel first worked with plants that differed in a single characteristic, such as flower color. A hybridization is a cross between two individuals that have different traits. A hybridization in which only one characteristic is examined is called a monohybrid cross . The offspring of such a cross are called monohybrids. Mendel noted that hybridizing true-breeding (P generation) plants gave rise to an F 1 generation that showed only one trait of a characteristic. For example, a true-breeding purple-flowering plant crossed with a true-breeding white-flowering plant always gave rise to purple-flowered hybrid plants. There were no white-flowered hybrids. Mendel wanted to know what happened to the white-flowers. If indeed a "heritable factor" for white-flower had disappeared, all future offspring of the hybrids would be purple-flowered - none would be white. To test this idea, Mendel let the F 1 generation plants self-pollinate and then planted the resulting seeds. Q: What term is used to describe a cross between two individuals that have different traits? Choices: - assimilation - fraternization - purebreed - hybridization A:
A: hybridization

Q: Answer the following question given this paragraph: A liquid that can interact with glass displays the property of adhesion . The attraction of the glass to the molecules is stronger than the attraction of the liquid molecules to each other. The liquid molecules are pulled up due to their stronger attraction to the glass. Water is one liquid that displays this property. Q: What property does liquid display when it interacts with glass? Choices: - property of repulsion - property of diffusion - property of oxidize - property of adhesion A:
A: property of adhesion
