Isn’t it 37.2 trillion cells if that is wrong sorry

Please find the detailed explanation of this statement below
Explanation:
Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.
However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.
Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.

The process is called condensation. the initial state- water vapor- is in a gas form. turning into droplets changes it into a liquid state.
Meteorite: If a small asteroid<span> or large </span>meteoroid<span> survives its fiery passage through the Earth’s atmosphere and lands on Earth’s surface, it is then called a meteorite. Another related term is bolide, which is a very bright meteor that often explodes in the atmosphere.</span>
