Bacteria cells in your small intestine can receive signals from somatic cells, indicating a particular type of food has been ingested and to expect it in the intestines soon. What is the most valid hypothesis you can construct from this information? Bacterial and eukaryotic cells must be able to undergo transduction with one another, so transduction may be an evolutionarily-conserved trait in both.
Bacteria and eukaryotes have evolutionarily-conserved similar enough mechanisms to be able to communicate.
The bacterial cells evolved many of the same organelles in their extranuclear cytoplasm that eukaryotic cells contain, showing evolutionary similarity.
The somatic cells must be emitting a hormone to communicate with the bacterial cells that have hormone recognition as an evolutionarily-conserved trait.

Explanation:

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
