What else can I help you with?
A membrane that allows only some materials to move in and out of the cell is . permeable semipermeable rigid bilayered?
Semipermeable. This type of membrane permits the passage of certain substances while blocking others based on their size, charge, or other characteristics.
Could the skin be a semipermeable membrane?
Yes, the skin can be considered a semipermeable membrane. It regulates the passage of substances in and out of the body, allowing certain molecules to pass through while blocking others. This property helps the skin to maintain homeostasis and protect the body from external threats.
What does it mean for a membrane to be semipermeable and how does this property affect the movement of substances across it?
A semipermeable membrane allows certain substances to pass through while blocking others. This property affects the movement of substances across the membrane by selectively allowing only certain molecules or ions to pass through, based on their size, charge, or other properties. This helps regulate the flow of substances in and out of cells or compartments, maintaining balance and allowing for essential processes to occur.
Movement of substances from higher to lower concentration across a semipermeable membrane that must have a specific protein carrier but no energy expenditure is called?
Facilitated diffusion is the movement of substances from higher to lower concentration across a semipermeable membrane with the help of specific protein carriers, without requiring energy input.
What are 2 characteristics of substances that do not allow them to pass through semipermeable membranes of living cells?
Large molecular size and hydrophobicity are two characteristics that prevent substances from passing through semipermeable membranes of living cells. Large molecules cannot fit through the small pores of the membrane, while hydrophobic molecules are repelled by the hydrophilic nature of the phospholipid bilayer.
Is a bubble semipermeable?
No, a bubble is not semipermeable. A bubble is a thin film of soapy water enclosing air or gas, which is not selectively permeable to different substances like a semipermeable membrane is.
A barrier that allows some substances in while keeping other substances out is said to be?
Semipermeable membrane.
Which part of a cell controls which substances can enter?
The cell membrane. It is described as semipermeable
A membrane that allows only some materials to move in and out of the cell is . permeable semipermeable rigid bilayered?
Semipermeable. This type of membrane permits the passage of certain substances while blocking others based on their size, charge, or other characteristics.
What do cell membranes do in plant cells?
they allow some substances to come in and out of the cell. this is because they are semipermeable.
What Semipermeable object that can pass through it what cannot?
A cell membrane is a semipermeable object that allows certain substances, such as water and small molecules, to pass through it while blocking larger molecules and ions. This selective permeability is important for controlling the movement of substances in and out of the cell.
What is promethium odor?
Promethium is a radioactive element and does not have a characteristic odor on its own. Any odor associated with promethium would likely be from compounds or substances it is combined with in a laboratory setting.
What is another semipermeable object?
Another semipermeable object is a cell membrane. It allows certain substances to pass through while blocking others, helping to maintain the cell's internal environment.
Could the skin be a semipermeable membrane?
Yes, the skin can be considered a semipermeable membrane. It regulates the passage of substances in and out of the body, allowing certain molecules to pass through while blocking others. This property helps the skin to maintain homeostasis and protect the body from external threats.
What do the terms semipermeable and selectively permeable refers to?
In the field of biology Semipermeable and Selectively Permeable refer to what substances the cell membrane allows to permeate (cross) into and out of the cell. The two terms can be used interchangeably.
How strongly a substances particles attract one another is what determines the substances?
The number of protons (aka atomic number) determines the element or substance.
What do you call a membrane that only allows certain substances to pass through it?
semipermeable membrane
