Larger organisms develop cells that each do very specific chores. They depend on other cells to deliver the required oxygen and nutrients. The circulatory system allows the cells that are in charge of providing these required substances to the other cells.

What is true about earth systems?
It is a large region of multiple organisms 👌
Definition of circulatory systems?
circulatory system is a large organism involving flow of fluid through the tissue and organs allowing the transport and exchange of substances such as nutrients,oxygen and waste products
Why have large organisms devolped systems like the respirtory system?
because they need to breath!
Why isn't it possible for a single celled organism to grow as large as us?
Single-celled organisms lack specialized organs and systems to support a larger size efficiently. They rely on diffusion for nutrient exchange and waste removal, limiting their size due to surface area-to-volume constraints. Without complex structures like circulatory and respiratory systems, they struggle to maintain internal balance in larger sizes.
Disadvantages of mainframes?
Mainframe computer systems have multiple disadvantages. They require a large amount of power, specialized support personnel, and special cooling systems to keep them from overheating.
How is the body form of a hydra limtied by its lack of a circulatory system?
The purpose of a circulatory system is to distribute nutrients and oxygen to every cell in the body. As hydras lack a circulatory system such distribution must be accomplished by diffusion along, which is a very slow process and inadequate for anything of any size. So the body form of a hydra is limited in size due to a lack of a circulatory system.
Why do cells in large organisms not tend to be in danger of bursting?
Large organisms have mechanisms to regulate the osmotic pressure inside their cells, maintaining them within a safe range. They also have structural support from tissues and cell walls. Additionally, large organisms have efficient waste removal systems that prevent the buildup of harmful substances inside cells.
What type of compounds are most nutrients and why does your body need them?
Organisms require water, vitamins, minerals, and salts to support the functioning of large molecules
Is your circulatory system open or closed?
A humans circulatory system is closed. Large creatures tend to have a closed system, while smaller creatures like insects and crustaceans have open circulatory systems. Closed is when there are vessels and the blood stays there. Open is when blood floats around the body. Hope it helps:)
Do all organisms must have organ systems?
No. Organ systems only develop in larger, complex organisms. E.g. amoeba, a single celled organism, is small enough that all its needs can be obtained by the relevant organelles through diffusion. A dog, a large multi-cellular organisms, needs a system to deliver its requirements to the necessary tissues .
Is earthworms unicellular?
No. An example of unicellular organisms would be bacteria. Earthworms are multicellular and contain organs and organ systems. Unicellular organisms are typically invisible to the naked eye except when in large groups (such as yeast).
