Answer:Multicellular and Eukaryotic are traits that can be true for every Kingdom past Protists on this branching tree diagram. These are the traits which were evolved that Protists just missed, plants and fungi got these traits and transferred them to their descent as well.
Explanation:
Answer:
The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop.
Explanation:
- Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
- If living organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
- This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
- If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.
Smooth muscle is the type of muscle tissue responsible for propelling food along the digestive tract.
Smooth muscle is a type of muscle tissue that can be found in the walls of hollow organs of the body such as the digestive system, urinary tracts, tubes such as blood vessels and reproductive system. Smooth muscles contracts involuntarily and allows the walls of organs to move. The layer of smooth muscle present in the digestive system helps to break down food and propel it along the tract. Food substances and liquid moves from one organ to the next through the muscle action.
