Answer: D. An adaptive process that allows children to deal more efficiently with their environment.
Explanation:
Synaptic pruning is a natural process between early childhood and adulthood which occurs in the brain. The brain removes the extra synapses during synaptic pruning. Synapses are brain structures that allow the neurons to transmit to another neuron an electrical or chemical signal.
Synaptic pruning is thought to help the brain transition from adolescence, when it can quickly learn and make new connections, to adulthood, when it is much more stable in its structure, but can concentrate on a single question for longer and conduct more complex thinking processes. Synaptic pruning make brain more adaptive to the external environment in early ages.
Hence, the correct option is D. An adaptive process that allows children to deal more efficiently with their environment.

Explanation:
Answer:
Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.
Part B:
The process 1 is meiosis. The process 3 is development by mitosis.
The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.
The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
