Answer:
Mitochondrial DNA.
Explanation:
Mitochondria is known as the power house of the cell and one of the important organelle responsible for the production of energy. Mitochondria contains its own DNA.
To understand the maternal ancestor history, the mitochondria DNA must be studied. The mitochondria is solely obtained from the mother as the egg contains large amount of cytoplasm that contains mitochondria. The mitochondria can never be inherited from paternal origin as the sperm contains few amount of cytoplasm and mitochondria.
Thus, the answer is mitochondrial DNA.
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.
