Which areas of the brain undergo major growth spurts during middle childhood?
djverab [1.8K]

sensory and motor areas undergo major growth spurts during middle childhood.

  • The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
  • Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
  • Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
  • More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
  • The brain is driven by the motor system, which also drives sensory stimulation and feedback.
  • These abilities must advance and grow in order to support behavior and academic learning.
  • Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.

A twisted zipper is used as a model of eukaryotic DNA. How could the model be developed to represent DNA replication in eukaryot
san4es73 [151]

Answer:

The model of the DNA can be related to a zipper. Just like the zipper, the two strands of the DNA are joined together by the hydrogen bonds present between the nucleotides. At the time of replication, the coiling of the two strands is undone just as the zipper is open. The two strands of the DNA open and separate just as the two stands of the zipper open and separate. Each strand can give rise to anew strand.

Just as the opening and closing of the zipper can cause damages in the zipper, just like this replication can cause errors in the DNA which lead to mutations.
