Why the nature of the graph of non uniform is always curve? |
|
Answer» Non - Uniform motion means velocity of the body is not constant i.e. body travels unequal displacement is equal time interval. Therefore displacement - time graph for non uniform motion will a curved path and tangent at any point given the velocity at that instant. Because it don\'t move in equal distance in equal interval of time |

Car accelerates from 18km/h to 36km/h in 5 sec find acceleration and distance travelled |
|
Answer» Dis=ut+at*t But time is in sec. Then we convert km to meter= u=1 m/s and v=2 m/s (by multiplying them by 5/18)=1*5+9*5*5=5+225=230mSo, distance is 230meter Acc.=v-u/2=(36-18)/2=9So, acc.=9 km/sec square |

What are the different methods to make water fit for drinking? |
| Answer» There are various methods through which normal water can be converted to potable water or drinking water\xa0Filtration: Filtration is very helpful in purifying water. Basically, there are two types of filters that can be found on the market. Some are those which rely on carbon filters and remove the bacteria and others are those which use chemicals like iodine for the treatment of water. Filters are very heavy and require frequent replacement and are also very expensive.\xa0Distillation: Distillation of water involves boiling water and collecting the vapor and leaving the bacteria and contaminants behind. Distilled water is one of the purest forms of water, 98% of the contaminants are removed from the home distillation system and it gives water which is purer than that from filters.\xa0Boiling: The easiest way to purify water is boiling. It neutralizes a majority of viruses and bacteria in the supply but it cannot remove all the heavy contaminants. | |

Explain the classification of epithilial tissues |
| Answer» On the basis of how they look, they can be divided as:a) Squamous Epithelial Tissue: This name is derived from a Latin word ‘squama’ which means the scale of a fish. As the name suggests, it looks like a scale or a single thin line. They are soft in nature.b) Cuboidal Epithelial Tissue: It is a type of epithelial tissue which consists of cuboidal cells.c) Columnar epithelium tissue: It is a uni-layer epithelial tissue comprised of columnar cells.By number of layers, they can be classified as:a) Simple Epithelial Tissue: If there is only a single layer of tissue then it is a simple tissue.b) Stratified Epithelial Tissue: If the tissues are made up of more than one layer then it is known as the stratified tissue. | |

what is major types of platid ? describe the green plastids involved in photosynthesis |
| Answer» Chloroplasts– Chloroplasts are the most known plastids which are responsible for photosynthesis. These are covered with thylakoids where the process of photosynthesis occurs.Chromoplasts– is a name given to an area for all the pigments to be kept and synthesized in the plant. These can be usually found in flowering plants, aging leaves and fruits.Gerontoplasts – These are basically chloroplasts that goes with the aging process. Geronoplasts refers to the chloroplasts of the leaves that helps the beginning to convert into different other organelles when the leaf is no longer using photosynthesis usually in autumn month.Leucoplasts – These are the non-pigmented organelles which are colorless. They are usually found in most of the non-photosynthetic parts of the plant like roots. They acts as a storage sheds for starches, lipids, and proteins depending on the needs of plant. | |

what is gene and where it is found ? give its function |
|
Answer» Genes are functional units of heredity as they are made of DNA. DNA present in the gene comprises of only 2 percent of the genome.Functions of Genes:\t\xa0Proteins are the most important materials in the human body which not only help by being the building blocks for muscles, connecting tissue and skin but also takes care of the production of enzymes. Enzymes are responsible for conducting all chemical processes and reactions within the body. So, it could be derived that protein synthesis is responsible for all activities carried on by the body and it is controlled by the genes.\t\xa0Genes consist of a particular set of instructions or specific functions. For example, globin gene was instructed to produce hemoglobin. Hemoglobin is a protein that helps to carry oxygen in the blood.\xa0\t Genes also control the functions of DNA and RNA. I think so gene is a cell or organisime that is sofrom ***** to ****** after reproduction |
