Question

read the paragraph.
despite its name, the pacific sea horse is actually a type of fish. its horse - shaped head gives it its name. this creature lives in the pacific waters off the west coast of the americas, from peru to southern california. like many other ocean fish, sea horses face the constant challenge of losing water to their saltier environment. when a sea horse sees a predator, its nervous system kicks into high gear.
which structure is responsible for transmitting signals from one nerve cell to the next?
○ nucleus
○ cell membrane
○ golgi body
○ ribosome

Explanation:

Wait, there seems to be an error in the options provided as none of the listed options (nucleus, cell membrane, Golgi body, ribosome) are the correct structure for transmitting signals between nerve cells (the correct structure is the synapse, and the components involved in signal transmission between neurons include neurotransmitters and the synaptic cleft, but among the given options, perhaps there was a typo. However, if we assume a possible typo and re - evaluate, the cell membrane is involved in the process of signal transmission at the synapse (for example, in the release and reception of neurotransmitters across the synaptic cleft, the cell membrane of the presynaptic and postsynaptic neurons is involved). The nucleus is for genetic control, Golgi body for processing proteins, and ribosome for protein synthesis. So among the given options, the cell membrane is the most related to signal transmission between nerve cells.

Answer:

B. cell membrane (assuming the options are labeled A, B, C, D with A: nucleus, B: cell membrane, C: Golgi body, D: ribosome)
