Document Summary
Connections between neurons are strengthened or weakened in response to activity lack of activity lose connections. If two synapses are often active at the same time, the strength of the postsynaptic response may increase at both synapses b. Multiple synapses active can strengthen response at all synapses. Opening up ion channels between nerve cells to keep information flowing. Activated when info needs to be retained when needed, retrieved into stm. ________________________________________________________________________________________________: the biosphere 2) ecosystems 3) communities 4) populations 5) organisms. _________________________________________________________________________________________________ the formation and function of molecules depends on chemical bonding. Atoms with incomplete valence shells can share or transfer valence electrons with other atoms. The difference in electronegativity between 2 atoms determines type of bond which forms. Nonpolar covalent bond- the atoms share the electron equally. Polar covalent bond- atoms do not share the electron equally. The polarity of water molecules results in hydrogen bonding. Polarity allows water molecules to form hydrogen bonds with each other.
