Insect respiration is independent of its circulatory system; therefore, the blood does not play a direct role in oxygen transport. Insects have a highly specialized type of respiratory system called the tracheal system, which consists of a network of small tubes that carries oxygen to the entire body.

Answer:
preoperational; concrete operations
Explanation:
Jean Piaget has given the theory of cognitive development in which he has mentioned four different stages including sensorimotor, preoperational, concrete operational, and formal operational.
Preoperational stage: This is the second stage in the cognitive development theory and starts from the age of two years and lasts through seven years of age in a child's stage. At this stage, a child is being engaged in manipulating symbols and symbolic play.
Concrete Operational Stage: This stage is the third stage and starts at seven years of age and lasts through eleven years of a child's life. In this stage, a child is engaged in using logical operations or thought and therefore the child can put logic only to physical objects.
