The DNA is being replicated during the S phase.
The lac genes encoding enzymes are lacZ, lacY, and lacA. The fourth lac gene is lacI, encoding the lactose repressor—"I" stands for inducibility. One may distinguish between structural genes encoding enzymes, and regulatory genes encoding proteins that affect gene expression.

Enzymes act as a catalyst they speed up reactions by providing a alternative pathway of lower activation energy by attaching to itself to its specific substrate and breaking down the energy required to start the process making it quicker.
And no they just speed the process up :)
3 g/cm3
Explanation:
Given parameters:
Volume of the plastic = 15cm³
Mass of the plastic = 45g
Unknown:
Density of the plastic = ?
Solution:
Density is given as the amount of substance i.e mass per unit volume.
Density =
The unit of density is g/cm³ or kg/m³
Inputting the parameters:
Density = = 3g/cm³
