Answer:
D. hotter rock rises and cooler rock sinks.
Explanation:
We know that as we move <u>towards Earth's center</u>, the <u>temperature rises</u>. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks <u>decrease the density of material </u>which makes it <u>move upward</u>. By <u>moving upward</u>, the molten rock <u>starts turning solid</u> and becomes <u>denser again</u>. Here, it <u>sinks back due to gravity</u>. This upward and downward movement of rocks due to density and temperature makes a convection cell.
PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
The answer is semiconservative replication. Semiconservative meaning that half of the original molecule (one of the two strands in the double helix) is conserved in the new molecule. Replication is the process by which double stranded DNA molecule is copied to produce two identical DNA molecules. It is one of the most basic process that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each stand of existing DNA acts as a template for replication.

Answer:
En el intestino delgado, estas células contienen microvellosidades, que son pequeñas proyecciones similares a pelos que aumentan la absorción de nutrientes. Estas proyecciones aumentan el área de superficie del intestino delgado permitiendo más área para que los nutrientes sean absorbidos.
