Inserting a portion of human DNA into the ring- shaped DNA of bacteria
The action potential spreads through an axon by depolarizing adjacent membrane to threshold.
- K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
- Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.
- Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.
- Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.

Answer: boom
Explanation: hope this is right :)
Helium does not react with any other substances, thus the substance’s internal structure is never greatly affected and thus helium cannot have any chemical properties.
Answer:
It occurs to create innovation in the existing technology.
Explanation:
A technological advancement is an attempt to develop current materials, devices, products or processes by further understanding of science. technological advancement provides innovations of existing technology or formation of new technology in order to better the life style and make easier our work. If the technological advancement did not occur, we are unable to increase efficiency of various instruments and machines.
