Answer:
Mechanisms enabling one cell to influence the behavior of another almost certainly existed in the world of unicellular organisms long before multicellular organisms appeared on Earth. Evidence comes from studies of present-day unicellular eucaryotes such as yeasts. Although these cells normally lead independent lives, they can communicate and influence one another's behavior in preparation for sexual mating. In the budding yeast Saccharomyces cerevisiae, for example, when a haploid individual is ready to mate, it secretes a peptide mating factor that signals cells of the opposite mating type to stop proliferating and prepare to mate (Figure 15-2). The subsequent fusion of two haploid cells of opposite mating types produces a diploid cell, which can then undergo meiosis and sporulate, generating haploid cells with new assortments of genes.

Although they flow near the bottom of the ocean, deep currents sometimes flow on top of other currents. while surface currents flow near the top of the ocean where they can reach depths of several meters. Some of the factors that control deep currents are salinity, density, and temperature. Deep current they occur deep in oceans which are influenced by salinity, temperature, and water.
A good example of deep current is Antarctic bottom water.
