Plasma membrane is permeable to water. Explain |
|
Answer» Yep The plasma membrane allows or permits the entry and exit of some materials in and out of the cell so the cell membrane is called a selectively permeable membrane. Some substances like CO2 or O2 gases can move across the cell membrane by a process called diffusion. The movement of water molecules (liquid) through such a selectively permeable membrane is called osmosis. Osmosis is the passage ot water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. If the medium surrounding the cell has a higher water concentration than the cell, the cell will gain water by osmosis. Such a solution is known as hypotonic solution. |

I don\'t understand perfectly the distance and displacement |
|
Answer» 1)when a body move from one position to another ,the distance travelled refer to the actual length of indirect path is called distance. 2) when a body move from one position to another, shortest distance between the initial position and final position of the body, along with direction is known as displacement. DISTANCE:The total path covered by a moving object or body is known as distance.DISPLACEMENT:The shortest distance between initial position and final position is said to be displacement The total dis travelled by any object from initial position to dinal position is called displacement Distance : Distance is the actual path of a body travelled by a body .It is a scalar quantity.S.I . Unit is m/s km/h .Displacement : Displacement is the shortest distance travelled by a body .It is a vector quantity .It\'s s.i. unit is m/s ;km/h. |
