Answer the following question given this paragraph: You can tell other things from tree rings too. In a good year a tree will produce a wide ring. A summer drought will produce a smaller ring. These variations will appear in all trees in a region. The same pattern can be found in all the trees in the area. This pattern helps scientist to identify a particular time period. Q: What size of ring will a summer drought cause in a tree? Choices: - giant - larger - medium - smaller A:
smaller
Answer the following question given this paragraph: You have ten times as many bacterial cells as human cells in your body. Luckily for you, most of these bacteria are harmless. However, some of them can cause disease. Any organism that causes disease is called a pathogen . Diseases caused by bacterial pathogens include food poisoning, strep throat, and Lyme disease. Q: Any organism that causes disease is called what? Choices: - a parasite - a virus - a microbe - a pathogen A:
a pathogen
Q: Answer the following question given this paragraph: Marine Biomes The ocean is the largest marine biome. It is a continuous body of salt water that is relatively uniform in chemical composition; it is a weak solution of mineral salts and decayed biological matter. Within the ocean, coral reefs are a second kind of marine biome. Estuaries, coastal areas where salt water and fresh water mix, form a third unique marine biome. Ocean The physical diversity of the ocean is a significant influence on plants, animals, and other organisms. The ocean is categorized into different zones based on how far light reaches into the water. Each zone has a distinct group of species adapted to the biotic and abiotic conditions particular to that zone. The intertidal zone, which is the zone between high and low tide, is the oceanic region that is closest to land (Figure 44.21). Generally, most people think of this portion of the ocean as a sandy beach. In some cases, the intertidal zone is indeed a sandy beach, but it can also be rocky or muddy. The intertidal zone is an extremely variable environment because of tides. Organisms are exposed to air and sunlight at low tide and are underwater most of the time, especially during high tide. Therefore, living things that thrive in the intertidal zone are adapted to being dry for long periods of time. The shore of the intertidal zone is also repeatedly struck by waves, and the organisms found there are adapted to withstand damage from the pounding action of the waves (Figure 44.22). The exoskeletons of shoreline crustaceans (such as the shore crab, Carcinus maenas) are tough and protect them from desiccation (drying out) and wave damage. Another consequence of the pounding waves is that few algae and plants establish themselves in the constantly moving rocks, sand, or mud. Q: The ocean is the largest marine biome. it is a continuous body of salt water that is relatively uniform in chemical composition; it is a weak solution of mineral salts and decayed what? Choices: - uranium atoms - rock shards - metal ores - biological matter A:
A: biological matter
Question: Answer the following question given this paragraph: Wave-cut cliffs form when waves erode a rocky shoreline. They create a vertical wall of exposed rock layers. Q: What are the cliffs called which are created when waves erode a rocky shoreline, leaving a vertical wall of exposed rock layers? Choices: - shear face - widow-makers - wave - theory - wave-cut A:
Answer: wave-cut

Answer the following question given this paragraph: The oldest animal fossils are about 630 million years old. The earliest animals were aquatic invertebrates. The first vertebrates evolved around 550 million years ago. By 500 million years ago, most modern phyla of animals had evolved. Q: What type of invertebrates where the earliest animals? Choices: - cnidaria - arachnids - annelids - aquatic invertebrates A:
**Answer**
aquatic invertebrates

Answer the following question given this paragraph: Anabolic reactions involve forming bonds. Smaller molecules are combined to form larger ones. For example, simple sugars are combined to form complex carbohydrates. Anabolic reactions require energy, so they are endothermic. Q: Anabolic reactions require energy, so they are considered what type of reaction? Choices: - autotrophic - exothermic - hydrostatic - endothermic A:
(Answer)
endothermic
