what are prokariotic and eukariotic cells |
| Answer» The cell having nuclear material without a nuclear membrane around it, are called prokaryotic cells. The nucleus of prokaryotic cell is not well organised. There is no nuclear membrane around the nuclear material in the prokaryotic cells. The nuclear material is in direct contact with the cytoplasm. All the prokaryotes are simple, unicellular organism. They were probably the first living things to evolve on the earth. For Ex: Bacteria, blur green algae are prokaryotes.The cells having nuclear material enclosed by a nuclear membrane are called eukaryotic cells. They have proper, well organised nucleus. The nuclear membrane in eukaryotic cell is not in direct contact with cytoplasm, it is separated from cytoplasm by the nuclear membrane.For Ex: Amoeba, cheek cell, onion peel cell , plants, animals, protozoa, fungi etc. | |

Why gas are compressible but not in liquid? |
|
Answer» Good explanation Keep it up Because solid particles doesnot have more space or no space between them and liquid padticles have spaces between them so they are easily copressible but all solids are incompressible Such as sponge it has fine poures between it so it can be compressed easliy. |
|
| 2212. |
Why are solid expand on heating? |
| Answer» The solid expand on heating because on heating the inter molecular force of attraction between the particles of solid decreases and it starts expanding | |
| 2213. |
Define the term latent heat of fusion of a solid how much is the latent heat of fusion of ice ? |
|
Answer» The amount of heat required by a body to change 1kg of a solid into liquid at atmospheric pressure is called latent heat of solid The amount of heat which is used for 1kg of ice change into water. |

Difference between evaporation &vaporisation ?? |
| Answer» Evaporation means change liquid into gas even before its boiling point. Vaporisation means change liquid into gas at its boiling point. | |
| 2216. |
Is the density of liquid is less than solid, then y ice float on water ???????? |
|
Answer» Solids have more density.......But ice floats on water because when water converts into solid there is some space between the particles which allows ice to flow on water Is ice is not a solid. ....becoz solid r packed very tightly Bcoz in ice particles have space between them and in that space air is available so ice float at water |

Plzz help me to undrstnd what is acceleration |
| Answer» The rate of change in velocity is called acceleration. Acceleration is generally denoted by a.Thus, Acceleration = {tex}\\frac{Change\\;in\\;velocity}{Time\\;taken}{/tex}⇒ a = {tex}\\frac{v\\;-u}t{/tex}Where, ‘a’ is acceleration, ‘v’ is final velocity, ‘u’ is initial velocity and ‘t’ is time taken for change.SI unit of acceleration (a) is m/s2. | |

What is the difference between chromatin and chromosomes? |
| Answer» \tChromatinChromosomes1. It is uncondensed part of nucleoprotein complex.1. Chromosomes are condensed parts of the nucleoprotein complex.2. Chromatin is observable in the interphase nucleus.2. Chromosomes are observable during M-phase or nuclear division.3. Chromatin is in the form of fine fibrils that run throughout the nucleus.3. Chromosomes are in the form of short thick threads or rods.4. Replication occurs in the chromatin phase.4. It cannot occur in chromosome phase.5. The replicas are not discernible.5. Replicas are visible as chromatids.6. It is active in controlling metabolism and other activities of the cell.6. Chromosomes are mainly meant for distribution of genetic information to the daughter cells.\t | |

What is chromatin material? |
| Answer» Chromatin Material : It is thin, thread like intertwined mass of chromosome material and composed of genetic substance like DNA and protein. Chromatin is the loose dense network of uncoiled chromosomes present in the nucleus of the cell. This is clearly visible in the interphase during cell division. The proteins which are associated with DNA can be histone proteins and non-histone proteins. During cell division chromatin condenses and forms coils which are densely packed to form rod like structures called as chromosomes. | |
