Q: Answer the following question given this paragraph: The trigeminal pathway carries somatosensory information from the face, head, mouth, and nasal cavity. As with the previously discussed nerve tracts, the sensory pathways of the trigeminal pathway each involve three successive neurons. First, axons from the trigeminal ganglion enter the brain stem at the level of the pons. These axons project to one of three locations. The spinal trigeminal nucleus of the medulla receives information similar to that carried by spinothalamic tract, such as pain and temperature sensations. Other axons go to either the chief sensory nucleus in the pons or the mesencephalic nuclei in the midbrain. These nuclei receive information like that carried by the dorsal column system, such as touch, pressure, vibration, and proprioception. Axons from the second neuron decussate and ascend to the thalamus along the trigeminothalamic tract. In the thalamus, each axon synapses with the third neuron in its respective pathway. Axons from the third neuron then project from the thalamus to the primary somatosensory cortex of the cerebrum. The sensory pathway for gustation travels along the facial and glossopharyngeal cranial nerves, which synapse with neurons of the solitary nucleus in the brain stem. Axons from the solitary nucleus then project to the ventral posterior nucleus of the thalamus. Finally, axons from the ventral posterior nucleus project to the gustatory cortex of the cerebral cortex, where taste is processed and consciously perceived. The sensory pathway for audition travels along the vestibulocochlear nerve, which synapses with neurons in the cochlear nuclei of the superior medulla. Within the brain stem, input from either ear is combined to extract location information from the auditory stimuli. Whereas the initial auditory stimuli received at the cochlea strictly represent the frequencyor pitchof the stimuli, the locations of sounds can be determined by comparing information arriving at both ears. Q: Which pathway carries somatosensory information from the face, head, mouth, and nasal cavity? A:

OPTIONS:
- posterior pathway
- dual pathway
- cranial pathway
- trigeminal pathway

A: trigeminal pathway

input: OPTIONS:
- amphipods
- crustaceans
- arthropods
- tubeworms Now, answer this question: Answer the following question given this paragraph: Some benthos live near vents on the deep ocean floor. Tubeworms are an example ( Figure below ). Scalding hot water pours out of the vents. The hot water contains chemicals that some specialized bacteria can use to make food. Tubeworms have the bacteria living inside them. The bacteria get protection and the tubeworms get some of the food. Q: Give an example of benthos that live near vents on the deep ocean floor. A:
A:
output: tubeworms

Answer the following question given this paragraph: Acids can be classified as monoprotic or polyprotic based on the number of acidic hydrogens they contain. Q: What can be classified as monoprotic or polyprotic based on the number of acidic hydrogens they contain? A:

OPTIONS:
- ions
- cations
- salts
- acids

Answer: acids

Problem: OPTIONS:
- protosperm
- phyla
- echinoderm
- gymnosperm
Q: Answer the following question given this paragraph: The most basic division is between nonvascular plants and vascular plants . Vascular plants are further divided into those that reproduce without seeds and those that reproduce with seeds. Seed plants, in turn, are divided into those that produce seeds in cones and those that produce seeds in the ovaries of flowers. Seed plants are called gymnosperms . Seed plants called angiosperms produce seeds in the ovaries of flowers . Q: What is another word for seed plants? A:
Answer: gymnosperm

Problem:OPTIONS:
- evolution
- speciation
- mutation
- genetic drift

Answer the following question given this paragraph: Genetic drift is a random change in allele frequencies that occurs in a small population. When a small number of parents produce just a few offspring, allele frequencies in the offspring may differ, by chance, from allele frequencies in the parents. Q: What is the term for a random change in allele frequencies that occurs in a small population? A:
****
A: genetic drift

Problem:OPTIONS:
- magma
- gases
- air
- water

Answer the following question given this paragraph: Geysers are also created by water that is heated beneath the Earth's surface. The water may become superheated by magma. It becomes trapped in a narrow passageway. The heat and pressure build as more water is added. When the pressure is too much, the superheated water bursts out onto the surface. This is a geyser . Q: Geysers are created when what is heated beneath the earth's surface? A:
****
A:
water
