Which area of the brain is the slowest to develop?

Answers

Answer:

The prefrontal cortex

Explanation:

The prefrontal cortex, which is responsible for higher-order cognitive functions such as decision-making, planning, impulse control, and reasoning, is generally the slowest area of the brain to develop. Its development continues into early adulthood, with significant changes occurring throughout adolescence. This delayed development of the prefrontal cortex is often associated with the development of executive functions and the ability to make complex decisions, which is why teenagers and young adults may sometimes exhibit impulsive behavior or have difficulty with long-term planning.

Golgi bodies
ribosomes

Answers

Answer;

-Mitochondria

Explanation;

-Cellular respiration is the process by which cells breakdown organic molecules such as glucose to yield energy in the form of ATP, which is used by the cells to drive cellular processes such as transport, growth and excretion among others.

-The process mainly occurs in the mitochondria of a cell. The mitochondria therefore acts as a power house of the cell. Cellular respiration involves three stages or phases(if aerobic), glycolysis, citric acid cycle and electron transport chain.

Most respiration occurs in mitochondria.
