Answer:

Replication is called semiconservative because half of the original strand is inherited.

Explanation:

In the semiconservative replication type, half of the original DNA or one strand of the double helix, is conserved in the daughter strand, while the other half is conserved in the second daughter strand. Therefore, at the end of replication two DNA double-stranded helix, are obtained, containing each one, 50% of the original DNA and 50% of the new one.

  • Another difference is <em>where does the exchange of gases takes place</em>, in fetuses blood is oxygenated in the placenta, in adults in the lungs.
  • The circulation between adults and fetuses differs in <em>where does the pressure increases</em>, in adults is on the left side of the heart, in fetuses on the right side.
  • Finally,<em> another important difference between adults and fetuses is the presence of shunts</em>, in fetuses these shunts allow both sides of the heart to work parallelly letting mix blood from both ventricles. This shunt gets closed after birth, so adults do not have them.
