How do substances like co2 and water move in and out of the cell ? |
|
Answer» Carbon dioxide comes from the cell respiration , it mix with blood (impure blood) and get filtered in lungs . Water also present in every cell as cytoplasm and maximum amount of plasma is water . The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. When the concentration of CO2 and water is higher in external environment than that inside the cell, CO2 and water moves inside the cell. When the concentration outside the cell becomes low and it is high inside the cell, they moves out. |

Derive the equation for velocity time relation (v=u+at ) by. Graphical method |
| Answer» From the below graph, v = final velocity of the particle, u = initial velocity of the particle, a = acceleration of the particle.Slope of v - t graph{tex}\\tan \\theta = \\frac { \\upsilon - \\nu } { t }{/tex}Again, acceleration a = slope of v - t graph.Hence, tan {tex}\\theta{/tex} = acceleration (a){tex}\\therefore a = \\frac { v -u } { t }{/tex}{tex}\\Rightarrow \\upsilon - u = at{/tex}{tex}\\therefore v =u+ at{/tex} | |
| 7158. |
Unit of time is stated twice in unit of acceleration . Why? |
| Answer» The first unit\xa0of time is associated with the velocity (e.g. feet per second). But acceleration is the rate of change of velocity, so another time parameter needs to be added. | |

How surface area and wind speed affect the rate of evaporation |
| Answer» Greater the wind speed, faster is the rate of evaporation. Greater the surface area, faster is the rate of evaporation. | |
| 7163. |
Explain evaporation? |
| Answer» Evaporation is a process by which water is transformed from liquid to gaseous state. Heat is the main cause of evaporation. Movement of air replaces the saturated layer with the unsaturated layer. Hence, the greater the movement of air, the greater is the evaporation. Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. Evaporation of water occurs when the surface of the liquid is exposed, allowing molecules to escape and form water vapour; this vapour can then rise up and form clouds. With sufficient energy, the liquid will turn into vapour.\xa0 | |

Define the following term Sublimation,Tyndal effect |
|
Answer» Sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. The amount of scattering depends on the frequency of the light and density of the particles. Conversion of a substance directly from solid to vapour or vice versa is called sublimation.Scattering of light due to the presence of small particles suspended in a heterogeneous mixture or colloidal solution is called Tyndall effect. |

What is plamolysis |
|
Answer» When a living plant cell loses water through the process of osmosis there is shrinkage of the contents of cell it is known plamolysis When a living plant cell looses water through osmosis there is contraction of protoplasm, this is called plamolysis. When endosmosis occurs then plant cell undergoes plasmolysis The water released by plant during transpiration then it get damage and shrinkage, this process is known as plamolysis. Plasmolysis is contraction of the protoplast of a plant cell as a result of loss of water from the cell. |
