Imagine that a researcher is examining the positioning of synaptic clefts in a region of the nervous system of adult mice. in one of his mice, he notices that synaptic clefts are about 100 nm wide. what can be said of this mouse?

This is likely a mutant mouse (as synaptic clefts are typically 10 to 20 nm wide). Given that neurotransmitters act over short distances, this mouse may demonstrate delayed responses to stimuli, or no responses at all.

That’s the answer
