Answer:
In multicellular organisms, the mechanism most directly responsible for directing development and maintaining homeostasis is gene "regulation"
Explanation:
Even though the organs present throughout the body helps in maintaining the homeostasis, But the systems like endocrine system and nervous system plays important role in sustaining and regulating it. The gene regulation is the increase and decrease of the specific gene products. Gene regulation can also be understood as the regulating process which helps in controlling ability of the cell to the environmental changes or can say the adaptability of the cell to changing environment done by gene regulation.
I believe it is a CELL CAPSULE. They are found in prokaryotic cells such as bacteria. Hope that helps. Have a nice day.
Peristalsis is the name for the waves of contractions that propel substance s along a tract. It is a series of wave-like contractions that moves food to different processing stations in the gastrointestinal tract and starts in the esophagus when the boluses of food are swallowed. The wave motion is produced by the longitudinal smooth muscles that line up the esophagus, stomach, small intestines and the colon and is triggered by presence of food.
