Q: Eutherian mammals possess a specialized structure called the corpus callosum that links what hemispheres? Read this paragraph and choose the correct option from the provided answers: possess a single, undivided lobe. Eutherian mammals also possess a specialized structure that links the two cerebral hemispheres, called the corpus callosum. Choices: - cortical - appendages - spatial - cerebral A:
cerebral

Q: Often primary producers, what term describes species considered the "base" or "bedrock" of a community, having the greatest influence on its overall structure? Read this paragraph and choose the correct option from the provided answers: Foundation Species Foundation species are considered the "base" or "bedrock" of a community, having the greatest influence on its overall structure. They are often primary producers, and they are typically an abundant organism. For example, kelp, a species of brown algae, is a foundation species that forms the basis of the kelp forests off the coast of California. Foundation species may physically modify the environment to produce and maintain habitats that benefit the other organisms that use them. Examples include the kelp described above or tree species found in a forest. The photosynthetic corals of the coral reef also provide structure by physically modifying the environment (Figure 19.24). The exoskeletons of living and dead coral make up most of the reef structure, which protects many other species from waves and ocean currents. Choices: - fundamental - consumable - primary - foundation A:
foundation

Q: Which temperatures cause particles of reactants to have more energy? Read this paragraph and choose the correct option from the provided answers: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ). Both food frying and food spoiling are chemical reactions that happen faster at higher temperatures. Choices: - non-existant - reducing - lower - higher A:
higher
