The answer in this question is an increase in the number of synapses. The changes that observe in the neural circuit when the gill-withdrawal reflex of the sea snail Aplysia has been successfully conditioned to a stimulus such as squirt of water from a Waterpik include an increase in the number of synapses.
The answer is A 15 percent
Answer:
Molecular evidence.
Explanation:
Different species of bacteria may look similar structurally/morphologically and can only be told apart through molecular sequencing of biomolecules such as DNA or proteins. This genetic sequencing will compare the sequences of the two species and the differences can be perceived and biologists can tell how far apart the species are.
Are you sure this isn't a physics question?
Higher pitched sounds have waves of a higher frequency and they have shorter wavelengths.
Hope that helps.
