Final answer:
Neurons can change their characteristics and functions without changing their connections through modifications in organelles and chemicals.
Step-by-step explanation:
Neurons can change their characteristics and functions without changing their connections with neural networks through various mechanisms. One way neurons can change is by modifying the properties of their organelles. For example, changes in the number and distribution of mitochondria can impact the energy metabolism of a neuron, which can influence its function. Additionally, chemical modifications, such as the presence of specific molecules or changes in the expression of certain proteins, can control the global function of a neuron. These modifications can alter the signaling and neurotransmitter release processes, ultimately changing the neuron's f
