Answer the following question given this paragraph: Mollusks, annelids, and arthropods are protostomes. Echinoderms and chordates are deuterostomes. This distinction is important. Why does it matter? It shows that echinoderms are more closely related to chordates than are the other invertebrate phyla. This is not apparent based on other, more obvious traits. Q: Mollusks, annelids, and arthropods are considered what? Choices: - protisines - detritivores - micelles - protostomes A:
protostomes
Answer the following question given this paragraph: What if you want a different approach? Let's say you don't want to wrap a flat piece of paper around a round object. You could put a flat piece of paper right on the area that you want to map. This type of map is called a gnomonic map projection ( Figure below ). The paper only touches Earth at one point. The sizes and shapes of countries near that point are good. The poles are often mapped this way to avoid distortion. A gnomic projection is best for use over a small area. Q: What type of map projection is used for small areas to avoid distortion? Choices: - unmeasured projection - mercator projection - equatorial projection - gnomic projection A:
gnomic projection
Q: Answer the following question given this paragraph: Average global temperature has been rising for the past several decades. Q: Average global temperature has been doing what for the past several decades? Choices: - fluctuating - falling - stabilizing - rising A:
A: rising
Question: Answer the following question given this paragraph: We use simple machines because they give us a mechanical advantage . Mechanical advantage is a measurement of the force amplification of a machine. In ideal machines, where there is no friction and the input work and output work are the same,. Q: What is is a measurement of the force amplification of a machine? Choices: - mechanical push - mechanical pull - force multiplier - mechanical advantage A:
Answer: mechanical advantage

Answer the following question given this paragraph: Diversifying Selection Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection, while the intermediate phenotypes are, on average, less fit. Known as diversifying selection (Figure 19.8), this is seen in many populations of animals that have multiple male forms. Large, dominant alpha males obtain mates by brute force, while small males can sneak in for furtive copulations with the females in an alpha male's territory. In this case, both the alpha males and the "sneaking" males will be selected for, but medium-sized males, which can't overtake the alpha males and are too big to sneak copulations, are selected against. Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum. Imagine a population of mice living at the beach where there is light-colored sand interspersed with patches of tall grass. In this scenario, light-colored mice that blend in with the sand would be favored, as well as dark-colored mice that can hide in the grass. Medium-colored mice, on the other hand, would not blend in with either the grass or the sand, and would thus be more likely to be eaten by predators. The result of this type of selection is increased genetic variance as the population becomes more diverse. Q: Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection; this is known as what? Choices: - extra selection - multiplying selection - shedding selection - diversifying selection A:
**Answer**
diversifying selection
Q: Answer the following question given this paragraph: Plants called epiphytes grow on other plants. They obtain moisture from the air and make food by photosynthesis. Most epiphytes are ferns or orchids that live in tropical or temperate rainforests (see Figure below ). Host trees provide support, allowing epiphyte plants to obtain air and sunlight high above the forest floor. Being elevated above the ground lets epiphytes get out of the shadows on the forest floor so they can get enough sunlight for photosynthesis. Being elevated may also reduce the risk of being eaten by herbivores and increase the chance of pollination by wind. Q: What type of plants grow on other plants? Choices: - bryophytes - parasites - legumes - epiphytes A:
A: epiphytes
