Scaffolding as a cognitive development technique was developed by Vygotsky. This technique is an instructional method or process in which a teacher demonstrates to a learner, how to solve a problem or learn a new skill, assist the learner, and at some point steps back and allows the learner to demonstrate the new skill or solve the problem alone. The teacher provides assistance to the learner during the process of learning till the learner can demonstrate the new skill or solve the problem independently.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
