There are 2 processes by whicha cell can get what it needs to live. These are 1) Active transport where the cell must expend some energy to move something into the cell (like food molecules) and out of the cell (like waste). The other 2) diffusion/osmosis. Diffusion is a process where things move from areas of higher concentration to areas of lower concentration without expending any energy, like the smell of bacon cooking in a kitchen filling an entire house. Try dropping a drop of food coloring into a glass of water and, without stirring, check it a few hours later. Osmosis is the diffusion of water.

What are diffusions of particles through protein channels called?
Science
What mechanisms are involved in homeostatic mechanisms?
homeostatic mechanisms involve: - the regulation of blood glucose - breathing rate - heart rate - oxygen levels - osmoregulation (water levels) - thermoregulation (temperature control)
The mechanisms involved with the regulation of cardiovascular function include?
turbulence volume and cardiac output
What evolutionary mechanisms might account for the origin and persistence of cell-to-cell signaling systems in unicellular prokaryotes?
yes
What are the 2 mechanisms involved when nutrient enter the bloodstream?
The vascular and lymphatic system
Explain the mechanisms involved in disrupting body systems?
Explain the mechanisms involved in disrupting body systems?
What are the control mechanisms involved in regulating the cell cycle and mitosis?
The signal that Signals the end of Growth phase and thusly the initiation of S-phase is generated when the Cell reaches a certain 'critical' size.
What are the principles involved in inversion of sucrose?
The principles that are involved in inversion of sucrose are the basic mechanisms for enzyme catalyzed reactions. These mechanisms were first proposed by Michaelis and Menten in 1913.
What are B cell mechanisms classified as?
call mediated immunity
What mechanisms are involved in homeostatic mechanisms?
homeostatic mechanisms involve: - the regulation of blood glucose - breathing rate - heart rate - oxygen levels - osmoregulation (water levels) - thermoregulation (temperature control)
What affects the rate of diffusions?
Temperature, Concentration and size of molecules :)

yes
Are osmosis and endocytosis passive transports?
It is an active transport,Transport mechanisms fall into two catagories passive and active. Passive transport mechanisms do not require the cell to do work for the substance to enter or leave the cell. Instead the energy involved comes from the kinetic energy of the molecules in solution. Active transport mechanisms involve the cell to use cellular energy usually in the form of ATP to power special protein pumps to bring material into the cell.Passive transport mechanisms Active Transport mechanismsSimple diffusionOsmosisFacilitated DiffusionSimple protein channelsGated channelsActive transport via protein pumpsBulk flow mechanismsendocytosisphagocytosispinocytosisexocytosisThe passive transport mechanisms and the protein pump mechanisms involve movement of substances as single molecules across the membrane. The "bulk" flow mechanisms endocytosis and exocytosis enable the cell to take in very large packages of molecules...say a food item from the environment. Many books treat these bulk flow mechanisms as separate from active transport for that reason.

The vascular and lymphatic system
