想请问大家几题升物问题 1. For the processing of visual information in the central nervous system of humans, the neuronal projections of ganglion cells to the left and right lateral geniculate nuclei (LGN) are A) all ipsilateral, meaning that left eye projections stay on the left side of the brain, and vice versa. B) all contralateral, meaning that left eye projections project to the right side of the brain, and vice versa. C) ipsilateral for the temporal side of each retina, and contralateral for the nasal side of each retina. D) ipsilateral for the nasal side of each retina, and contralateral for the temporal side of each retina. E) randomly crossed in terms of which side of the retina projects to either the left or right side of the brain. Answer: C 2.Experiments with genetically altered mice showed that the mice would consume abnormally high amounts of bitter-tasting compounds in water after their A) hormone receptors for digestive hormones were reduced or eliminated, showing that bitter tastes are reinforced by digestive responses. B) salt-taste cells were altered to express receptors for bitter tastants, suggesting that animals have unregulated salt appetites. C) visual sense was reduced or eliminated, suggesting that mice learn visual cues about bitter tastes. D) olfactory sense was reduced or eliminated, suggesting that mice learn odor cues about bitter tastes. E) sweet-taste cells were altered to express receptors for bitter tastants, suggesting that the sensation of taste depends only on which taste cell is stimulated. Answer: E 其实我是连题目都看不太懂 想请教各位高手帮帮忙 诚心感谢 --
