The synaptic pruning during childhood results in a reduction in density of nerve cells, thus increasing the brain's efficiency.
<span>Synaptic pruning, which can include both axon and dendrite pruning, is the process of synapse elimination that occurs usually in early childhood. It is thought that this is the brain’s way of removing connections in the brain that are no longer needed and a way of maintaining more efficient brain function.</span>
Answer:
When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.
Competition allows science to advance at a faster pace.
Think of it as an arms race: when a country builds one battleship, their enemy builds two. This continues as both countries try to outdo each other. Competitive science works the same way.
Answer:
Cell wall. The plant cell wall accounts for the turgidity and the rigidity in plants. The cell wall protects the plant cell from bursting due to the influx of water. Rather than bursting, the cell is able to withstand the osmotic pressure exerted by the water molecules.
