A- A Concentration Gradient
B- A Selectively Permeable Membrane
C- A Source of Energy
D- A Protein
The Answer Is (A)
Diffusion can occur without a semipermeable membrane, as diffusion is simply movement of a substance from high to low concentration. A source of energy is needed only for active transport. Proteins are needed if the the particles transported are too big to pass the semipermeable membrane.
What else can I help you with?
Why do cells use the process of diffusion?
Diffusion is essential for cells to bring nutrients and releasing wastes without spending energy.
Amino acids absorbed through two processes of?
Amino acids are absorbed through two processes: active transport and facilitated diffusion. Active transport requires energy and is used for absorption of essential amino acids, while facilitated diffusion does not require energy and is used for absorption of non-essential amino acids. Both processes occur in the small intestine.
How is diffusion of gases in water is essential explain with example?
Diffusion of gases in water is essential for processes like respiration in aquatic organisms, where oxygen from the water diffuses into the organism's bloodstream for cellular respiration, and carbon dioxide produced by the organism diffuses out. For example, fish extract oxygen from water through their gills via diffusion, allowing them to breathe and survive underwater.
Movement of molecules from an area?
The movement of molecules from an area of higher concentration to an area of lower concentration is called diffusion. This process occurs spontaneously and is driven by the random motion of molecules. Diffusion helps to establish equilibrium and is essential for various biological processes.
What is the Bill of General Diffusion of Knowledge?
The Bill of General Diffusion of Knowledge was proposed by James Madison in 1785 to establish a system of public education in Virginia that would promote the general diffusion of knowledge among the population. It aimed to provide a foundation for an educated citizenry, essential for maintaining a functioning democracy. However, the bill was not passed by the Virginia legislature.
Why do cells use the process of diffusion?

Why are the processes of osmosis and diffusion essential for life?
Because without them, your nipples would not produce mountain dew.
Features of diffusion?
Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. It is driven by the random motion of molecules and does not require energy input. Diffusion is essential for processes such as gas exchange in the lungs and nutrient uptake in cells.
How does osmosis and diffusion help organ transplants?
Organs to be transplanted lack oxygen, nutrients and other essential materials, since they have been idle for a long time.Osmosis and diffusion help these organs filled with these essential materials, such as water, nutrients and materials, as if they were attached in the human body.BTW, osmosis is the flow of water from less concentration of solutes to high. Diffusion is the scattering of particles from higher cont to lower.
Amino acids absorbed through two processes of?
Amino acids are absorbed through two processes: active transport and facilitated diffusion. Active transport requires energy and is used for absorption of essential amino acids, while facilitated diffusion does not require energy and is used for absorption of non-essential amino acids. Both processes occur in the small intestine.
Why is diffusion important to animals?
Diffusion is important to animals because it allows for the movement of molecules such as oxygen and nutrients across cell membranes to where they are needed in the body. This process ensures that cells receive essential resources for metabolic processes and waste products are removed efficiently. Diffusion is crucial for maintaining homeostasis and sustaining cellular functions in animals.

How do diffusion and osmosis affect cells?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, which helps cells take in nutrients and get rid of waste. Osmosis is the diffusion of water across a selectively permeable membrane, allowing cells to maintain their internal balance of water and solutes. Together, diffusion and osmosis are essential processes for cells to function properly and maintain homeostasis.
What are the types of cultural diffusion?
contagious diffusion, relocation diffusion, expansion diffusion, stimulus diffusion, hierarchical diffusion.
The spreading out of a substance from an area of high concentration to an area of low concentration is called .?
diffusion
How do cells use diffusion and osmosis?
Cells use diffusion to move molecules such as oxygen, carbon dioxide, and nutrients into and out of the cell without requiring energy. Osmosis, a specific type of diffusion, involves the movement of water across a semi-permeable membrane to maintain the cell's internal environment and regulate cell volume. Both diffusion and osmosis are essential processes for maintaining cellular function and homeostasis.
