What else can I help you with?
An opening in the earth's crust from which volcanic materials pass through to the earth's surface is called an?
a volcano probobly
What is the membrane which lines the cavity that contains the heart called?
Pericardium
Is a membrane called the endocardium covers the heart true or false?
true
Were does the electron transport chain occur in the cell?
In the cristae of the organelle called the mitochondria.
How do you draw a mitichondria?
To draw a mitochondrion, start by sketching an oval or bean-shaped structure to represent its outer membrane. Inside, draw a smaller, folded inner membrane, which resembles squiggly lines or curves to indicate the cristae. You can add a fluid-filled space inside the inner membrane, called the matrix, and label the outer membrane, inner membrane, and cristae for clarity. Finally, you might include small dots to represent ribosomes or enzymes within the matrix.
What is the abillity of a membrane to allow materials to pass through called?
permeability
A membrane that allows some but not all materials to pass through it is called .?
This sort of membrane is said to be semipermeable.
What is the ability of a cell membrane to allow materials to pass through it is called?
permeability
What is the ability of a cell membrane to allow materials to pass through called?
permeability
What is energy free movement of materials through a cell membrane?
Energy-free movement of materials through a cell membrane is called passive transport. This process includes diffusion, osmosis, and facilitated diffusion, where molecules move from an area of high concentration to an area of low concentration without the input of energy.
The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
What is it called when an input of energy is required to move materials through a cell membrane?
Active Transport
What is the movement of materials across a cell membrane without using energy?
This type of movement is called simple diffusion.
How do materials get into and out of the cell?
Through proteins in the membrane.
What is it called when a molecule moves a membrane through a protein channel without using energy?
passive transport
What are materials that transmit light without scattering called?
Materials that transmit light without scattering are called transparent materials. These materials allow light to pass through them with little to no distortion, making them ideal for applications like windows and lenses.
