Answer the following question given this paragraph: A solute generally lowers the freezing point of a solvent, which is called freezing point depression. For example, spreading salt on an icy road melts the ice. Q: A solute generally does what to the freezing point of a solvent? Choices: - regulates it - raises it - increases it - lowers it A:
lowers it

Answer the following question given this paragraph: Particles of a hypothetical ideal gas have no significant volume and do not attract or repel each other. In general, real gases approximate this behavior at relatively low pressures and high temperatures. However, at high pressures, the molecules of a gas are crowded closer together, and the amount of empty space between the molecules is reduced. At these higher pressures, the volume of the gas molecules themselves becomes appreciable relative to the total volume occupied by the gas (Figure 9.36). The gas therefore becomes less compressible at these high pressures, and although its volume continues to decrease with increasing pressure, this decrease is not proportional as predicted by Boyle's law. Q: At high pressures, how are the molecules of a gas crowded? Choices: - few together - further apart - small together - closer together A:
(Answer)
closer together
Ques: Answer the following question given this paragraph: Plants can respond to the change of season by losing their leaves, flowering, or breaking dormancy. Q: Plants can lose their leaves, flower, or break dormancy in response to a change in what? Choices: - events - periods - averages - seasons A:
Ans: seasons
(Q).
Answer the following question given this paragraph: If the word fish makes you think of cute little goldfish in a tank, check out the anglerfish pictured in Figure below . It's also called a black sea devil. Surprisingly, goldfish and angler fish aren't all that different from each other as far as fish diversity goes. Both fish are placed in the same fish class. Clearly, fish are a diverse and interesting group of vertebrates. Q: Fish are a diverse and interesting group of organisms in what sub-phylum? Choices: - mammals - invertebrates - organelles - vertebrates A:
(A).
vertebrates
Ques:Answer the following question given this paragraph: Sound is a form of energy that travels in waves through matter. The ability to sense sound energy and perceive sound is called hearing . The organ that we use to sense sound energy is the ear. Almost all the structures in the ear are needed for this purpose. Together, they gather sound waves, amplify the waves, and change their kinetic energy to electrical signals. The electrical signals travel to the brain, which interprets them as the sounds we hear. Q: What type of energy travels through matter in wave form? Choices: - vibrational - magnetic - light - sound A:

Ans:sound
Ques:Answer the following question given this paragraph: Thalamus The thalamus is a collection of nuclei that relay information between the cerebral cortex and the periphery, spinal cord, or brain stem. All sensory information, except for the sense of smell, passes through the thalamus before processing by the cortex. Axons from the peripheral sensory organs, or intermediate nuclei, synapse in the thalamus, and thalamic neurons project directly to the cerebrum. It is a requisite synapse in any sensory pathway, except for olfaction. The thalamus does not just pass the information on, it also processes that information. For example, the portion of the thalamus that receives visual information will influence what visual stimuli are important, or what receives attention. The cerebrum also sends information down to the thalamus, which usually communicates motor commands. This involves interactions with the cerebellum and other nuclei in the brain stem. The cerebrum interacts with the basal nuclei, which involves connections with the thalamus. The primary output of the basal nuclei is to the thalamus, which relays that output to the cerebral cortex. The cortex also sends information to the thalamus that will then influence the effects of the basal nuclei. Q: The primary output of the basal nuclei is to the thalamus, which relays that output to where? Choices: - effect cortex - Back cortex - suffering cortex - cerebral cortex A:

Ans:
cerebral cortex
