What else can I help you with?
The cell membrane controls what goes in and out of the cell true or false?
True. The cell membrane is selectively permeable, meaning it regulates the movement of substances in and out of the cell to maintain internal balance and protect against harmful substances.
Osmosis is the process by which molecules tend to move from an area of higher concentration to an area of lower concentration is this true or false?
True. Osmosis is the movement of solvent molecules (usually water) across a selectively permeable membrane from an area of higher concentration to an area of lower concentration to equalize the concentration on both sides of the membrane.
Is it true that the transport proteins span the cell membrane allowing the selectively permeable membrane to regulate which molecules enter an leave the cell?
false
The structure and properties of the cell wall allow it to be selective and maintain homeostasis True or false?
True. The cell wall is selectively permeable, allowing only certain molecules to pass through, which helps maintain homeostasis by regulating what enters and exits the cell. Additionally, the cell wall provides structural support and protection for the cell.
Movement of water down its concentration gradient?
Osmosis is the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. This process is passive and does not require energy input. Osmosis plays a crucial role in maintaining the balance of water in cells and tissues.
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
The cell membrane controls what goes in and out of the cell true or false?
True. The cell membrane is selectively permeable, meaning it regulates the movement of substances in and out of the cell to maintain internal balance and protect against harmful substances.
How do particles move through a permeable membrane according to diffusion?
Yes, that is very true, especially with osmosis (the passing of water through a selectively permeable membrane).
Osmosis is the process by which molecules tend to move from an area of higher concentration to an area of lower concentration is this true or false?
True. Osmosis is the movement of solvent molecules (usually water) across a selectively permeable membrane from an area of higher concentration to an area of lower concentration to equalize the concentration on both sides of the membrane.
Is it true that the transport proteins span the cell membrane allowing the selectively permeable membrane to regulate which molecules enter an leave the cell?
false
Is it true or false that ribosomes are permeable to the nuclear membrane?
False. Ribosomes are not permeable to the nuclear membrane. They are synthesized in the nucleolus of the nucleus and then transported out through nuclear pores to the cytoplasm where they function in protein synthesis.
Plasma membrane is best described as a fluid mosaic model?
Yes, the plasma membrane is best described as a fluid mosaic model because it consists of a fluid lipid bilayer with embedded proteins that can move laterally within the membrane. This fluidity allows for flexibility and dynamic interactions between the membrane components.
Water pass true the cell membrain what does it call?
Water passing through the cell membrane is called osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration across a selectively permeable membrane.
Is water enters a cell through a cell wall by a process called osmosis true?
It is not accurate to say that water enters a cell through a cell wall via osmosis. Osmosis is the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. In plant cells, water enters through the cell membrane and moves into the vacuole.
The structure and properties of the cell wall allow it to be selective and maintain homeostasis True or false?
True. The cell wall is selectively permeable, allowing only certain molecules to pass through, which helps maintain homeostasis by regulating what enters and exits the cell. Additionally, the cell wall provides structural support and protection for the cell.
Would it be true to say that synovial membrane is a true membrane?
false
Is a membrane called the endocardium covers the heart true or false?
true
