Groundwater is defined as the water present beneath the Earth's surface in rock and soil pores and in fractures of rock formations.
<h3>What are Saturated and Unsaturated Zones of Groundwater?</h3>
- The saturated zone of groundwater refers to the zone in which pores and rock fractures are filled with water only. The top part of the saturated zone is referred to as the water table.
- Unsaturated zone refers to the zone present below the saturated zone and consists of air and water pores. The soils and rocks are also found in this zone. It is not readily available water for human consumption.
Thus, the saturated zone has water, while the unsaturated zone has soil, rock, and air with water.

The right answer is the promoter.
• The promoter is a nucleotide sequence that allows the transcription of the gene into mRNA. It is recognized by the RNA polymerase that initiates transcription. During the synthesis of the RNA, the promoter indicates which gene must be expressed and therefore which proteins the cell must produce. In an operon it is common to all genes.
• The operator is a segment of DNA and / or messenger RNA to which a chemical signal (a regulatory molecule) binds. It can be either a repressor signal or a transcription activating signal (DNA operator) or translation (RNA operator) of the genes of the operon. The RNA polymerase does not recognize this structure.
The CEREBRUM is responsible for those functions
