What else can I help you with?
What do you call a thin solids that allow certain substances to diffuse through them?
Semi-permeable membranes are thin solids that allow certain substances to diffuse through them while preventing the passage of others.
What do you call the movement of water across cell membranes?
osmosis
What substances that can pass through call membranes by diffusion include?
Oxygen
What do you call the passage of light through an object?
The passage of light through an object is called transmission. This process occurs when light passes through a material without being absorbed or reflected.
What do you call a material that does not let electricity pass through it?
A material that does not conduct (or allow the 'passage' of) electricity is called an "insulator".
Why will water diffuse into a bacterial cell placed in fresh water?
Its through a process call osmosis 'the passage of a solvent through a semipermeable membrane from a less concentrated to a more concentrated solution until both solutions are of the same concentration'. This means that if the water is pure it will move into the cell. however if you use sugar water with a higher concentration than inside the cell water will move out. you can get the bacteria to shrink
What is PPROM?
PPROM is an acronym for Preterm Premature Rupture of Membranes. To explain it, we should break it apart: * Rupture of membranes (ROM) is the normal breaking of the amniotic membranes that occurs during labor. Most people call this "breaking their water." * Premature rupture of membranes (PROM) occurs when the amniotic membranes are ruptured (water breaks) before actual labor has started. Sometimes, physicians may rupture membranes prematurely in an attempt to induce or augment the labor process. PROM indicates this was not an intentional ROM * Preterm premature rupture of membranes (PPROM) indicates that there is premature rupture of membranes before the child has been carried to term (> 36 weeks gestation).

What are the flattered membranes in chloroplast?
We call them thylakoids. We are using them grana too.
How is a plant and animal cell alike?
they both have organelles and call membranes and a nucleus
What are the two phospholipids that makes up call membranes called?
proteins and starch.
What do you call a passage way starting with h?
a hall or hallway
Is an ants bum hole the smallest hole in the world?
No. Every cell in your body (or in the body of any living plant or animal or fungus or bacterium) has tiny holes in the little membranes (sheets) that cover their parts. These holes are so small that only particular molecules or even atoms can get through. For instance, some of them will let water through, but not salt or alcohol dissolved in that water. Then there are spaces between atoms and some particles like electrons can get through; would you call them holes?
