Once dna is cloned, we have the problem of finding the piece of dna that holds our gene of interest. explain how nucleic acid hybridization will accomplish this task.

This can be done with the principle of complementary base parings with another DNA molecule

Explanation:

Since the DNA molecules have unchanged complementary  base paring of purines with pyrimidines; this specific characteristic can be used   to detect the cloned DNA through complementary A-T and C-G on the cloned DNA  by the hybridized DNA strands.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.

explanation:

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
