Why do meristems lack vacuoles?? |
| Answer» Meristematic cells divide frequently and give rise to new cells and hence they need dense cytoplasm and\xa0thin cell wall. Vacuoles causes hindrance in cell division as it is full of cell sap to provide turgidity and rigidity to the cell. Also vacuoles basically serve the purpose of storing of nutrients, excess salts etc. Meristematic cells do not need to store these nutrients as they have compact shape. | |

What would happen if all the oxygen present in the environment is converted into ozone? |
| Answer» If all O2 present in the environment is converted to ozone then life on earth will come to halt. This is because all the animals and even plants require O2 to carry out various metabolic processes. If there is no O2 than we will not be able to respire. Ozone is harmful both for plants and animals. Ozone affects chloroplast of plants and hence photosynthesis. In animals and humans it causes respiratory problems such as asthma and irritation of chest. So, life on earth won\'t be possible in such case. | |

What are lichens and give example? |
|
Answer» A Lichen is a mutually beneficial relationship of fungi and algae. In which fungi is responsible for absorbing of water from the corresponding area and algae is responsible for preparing of food because algae is having chlorophyll while fungi is not having. Such relationships are called symbiotic. A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi in a symbiotic relationship. The combined lichen has properties different from those of its component organisms. They are used are air pollutants for SO2.\xa0 |

Explain why some of the leaves may get detached from a tree if we vigorously shake its branch |
|
Answer» when we vigorously shake a branch of tree some of leaves may get detached and account of inertia of the rest of the leaves ,the branchb come in motion and the leaves be tried in the position of rest therefore they get detached.☺️ Badshah In the inital situation the tree and their leaves are in rest but when we vigourously shake its branch the tree and its branch comes in motion but the want to be in rest due to inertia of rest so weak leaves get detached from tree See it is because of inertia of leaves.otherwise this is the question of book.i know that Akbarabadi |

How motion is relative?explain with example |
| Answer» An observer on the earth records various motions, that of a train, a bus, a bird, a plane and so on. But consider an hypothetical scenario with an observer on sun. He can as well perceive these motions i.e. a train, a bus on earth.But the two observers will find the velocity and accelerations differently and unmatching. Hence, unless the observer specifies it\'s frame of reference the description of motion is meaningless. Motion is a relative term. | |

What is hybridisation from biology |
| Answer» Hybridization is the crossing of dissimilar individuals to produce best of both organisms. It might be of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization). One advantage of hybridization is that it can combine disease resistance of one organism with the production capacity of another.\xa0 | |

Why does the level of water not change when common salt is dissolved in wster |
|
Answer» Because particles have space between them Common salt dissolves in water i.e. its atoms occupy the spaces in the water molecules.Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions.Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. Because salt dissolve in it |

Modal on electromagnets |
| Answer» Electromagnets are made out of a coil of wire (wire curled in series). This is more effective in producing a magnetic field than just a wire running straight. This effect can be strengthened by winding a wire tightly around a powerful core, made of magnetic material, such as iron. The picture above shows a coil wound around an iron nail. On its own, the iron nail is not magnetic. | |

Convert 1N into dynes |
| Answer» Change one system of unit in other system by first write the quantity in terms of fundamental quantities and then apply unit conversion rules. For example if you want to change unit of force Newton into dyne i.e. from SI unit to CGS unit.First break Newton into fundamental units.As, force = mass × accelerationi.e. 1 N = 1 kg × 1m/s2 Now to change it into CGS system.1 kg = 1000 g and, 1 m = 100 cmNow in CGS unit, 1 N = (1000 g) × 100cm/s21 N = 100000 g cm/s2 = 105 dyne | |

Function of cytoplasm? |
| Answer» \tMost of the important activities of the cell occur in the cytoplasm. Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.\tCytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place. Without cytoplasm, the cell would be deflated and materials would not be able to pass easily from one organelle to another.\tCytosol is the part of the cytoplasm that does not contain organelles. Instead, cytosol is confined by the boundaries of a matrix which fills the part of the cell that does not contain organelles. | |
