The correct answer is: prefrontal cortex
Synaptogenesis or formation of synapses begins about the 23rd week of gestation. The peak of synapse production is achieved at different periods. The massive overproduction of synapses that occurs in early childhood is followed by a gradual reduction of them also known as "synaptic pruning". “Synaptic pruning” happens during childhood, and during adolescence.
The brain continues to grow and develop, but the overall number of neurons and synapses are reduced by up to 50%. This is process that is experience driven: unnecessary neuronal structures are removed and replaced by more complex and efficient structures, that are more required to the demands of adulthood.
The answer is 5. Meiosis I reduces the ploidy of a cell by half.Therefore, if a cell was diploid (2n), then at the end of meiosis I, the two formed daughter cells will have haploid (n) number of chromosomes. Meiosis II is similar to mitosis and does not reduce ploidy.
(2n)/2= 10/2; n = 5

The air begins to rise into the atmosphere. When air rises, it cools down and condenses into precipitation and clouds. This is why an approaching low pressure system means an increased chance for clouds, rain, or snow. It is called "low pressure" because as air rises, the air pressure is lower at the surface.
