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.

sp2606 [1]

Answer: Option B

The concentration of protein in the postglomerular blood is high comparef with arterial blood because as water passes into the capsule, the concentration of protein in the blood will increase.

Explanation:

Kidneys are bean shaped organs present in veterbrates and it is located in the retroperitoneal space. Kidney filtration involves where blood passes through the afferent arterioles and enters the glomerulus where blood that can be filter like nitrogenous waste and water moves towards the glomerulus and nonfilterable substances such as cells and serum albumins pass out through efferent arterioles. Thee concentration of protein increases from arterial to the post glomerular because some of the water molecules diffuses to the filtrate therefore, reducing water concentration. This lead to increase in concentration of protein because water is not available to diffuse the protein.
