What is haploid |
|
Answer» Hat A haploid is a cell or organism that has a single set of chromosomes that are not paired. The haploid gamete is normally produced during plant cell division. During fertilization, these cells normally merge with other similar haploid cells. A haploid cell only has half the number of chromosomes as are present in diploids. |

describe the structure and function of plastids |
| Answer» Plastids: They are present in plant cell but absent in animal cell. They have their own DNA and Ribosomes. They have a power to divide. They are involved in photosynthesis because they have green pigment called chlorophyll.They are called as kitchen of cell.Each chloroplast is surrounded by 2 membranes.It has 2 regions:1) Grana (site of light reaction):It is a stack of membrane bounded,flattened discoid sac containing the molecules of chlorophyll.2)Stroma (site of dark reaction):Homogeneous matrix in which grana are embedded. They contain photosynthetic enzymes, DNA, ribosomes.Functions1)They trap solar energy and utilise it to manufacture food for plant.2)Chromoplast impart green colour to flowers.3)They store food in form of carbohydrates, fats and proteins. | |

Which state of matter has the highest density and why |
|
Answer» Solids state of matter have the highest density because the intermoulicular Force is very high. They were tightly packed and their particles does not have space between them Solids because it has no intercellular space between them and are very tightly packed Solid because its intermolecular distance is very close to each other as compared to other states |

Short note on endoplasmic reticulum |
| Answer» It is a large network of of membrane bound tubes and sheets. The ER is of two types : rough ER and smooth ER . The rough ER contains ribosomes on its surface whereas the smooth ER does not contains ribosomes on its surface. The ER helpes in transport of materials between various regions of the cytoplasm. It serves as the cytoplasmic framework providing a surface for some of the biochemical activities of the cell. It also functions as the manufacturing surface in a cell . | |

How many types of inertia are there . explain |
| Answer» Three types of inertia are:1. Inertia of rest: The ability of a body to resist any change in its state of rest. Example: Person sitting in a car falls backwards, when the car suddenly starts. It is because the lower portion in contact with the car comes in motion where as the upper part tries to remain at rest due to inertia of rest.2. Inertia of motion: The ability of a body to resist any change in its state of motion. Example: An athlete runs a certain distance before taking a long jump because the velocity acquired by running is added to the time of jump, so that it can cover a long distance.3. Inertia of rotation: The ability of a body to resist any change in its state of rotation is inertia of rotation. . Example: When a car moves round a curve the person sitting inside is thrown outwards in order to maintain his direction of motion due to inertia of motion. | |

Give reasons water is gas at 0 degree celcius |
|
Answer» Because at 0degree the bond between hydrogen and oxygen will break Because it is water |
|
| 2393. |
Give reason water at room temperature is a liquid |
| Answer» Water at room temperature is liquid because in water the intermolecular force is strong enough to keep its particles bound to each other and the melting point of water is below room temperature and the room temperature is normal than our environment\'s temprature so it cannot convert into water vapours | |
| 2394. |
For any substance,why does the temprature remain constant during the change of state |
| Answer» Because the heat supplied to a substance is used up during the chage of state in overcoming the intermolecular force and the heat is absorbed for bounding so the temperature does not increase or decrease | |

What is displacement and distance? |
|
Answer» Displacement----it is the shortest distance from initial point to final point .Distance-----the actual length from 1st point to the 2nd point. Displacement is vector quantity while distance is scalar quality. The shortest distance between two points is known as displacement the actual length between two points is known as distance |

Advantage of manure |
|
Answer» They provide humus to soil which improves the physical and chemical property of soil. Manure help on restoring soil texture and also improves water holding capacity of soil. It alsomakes the soil porous and airy,replenshih all the nutrients. Manure is used to kill the weeds By using manure, field do not get infertile. |
