Why are manure and fertiliser used in field |
| Answer» As the seeds germinate, the growing saplings should be provided with nutrients and water. Hence soil should be replenished with minerals in periodic intervals of time. Manure and fertilisers supply nutrients to the soil. This is called as replenishment of nutrients. Manure and fertilisers replenish the soil by supply nutrients to the soil. Manure is the organic matter added to the soil to replenish it with nutrients. The wastes from household, animal dung and agricultural wastes are buried in small pits. Decomposition by bacteria and earthworms occurs in these pits converting organic wastes into manure. Manure increases the water retention capacity of soil.Manure is ecofriendly and replenishes the soil with nutrients which can persist for longer time whereas fertilisers though not ecofriendly supply nutrients for immediate usage by the plants. Fertilisers supply specific type of nutrients for the plant. Fertilisers are the chemicals which add minerals like potassium, phosphorus and nitrates to the soil. | |

What is myosis |
| Answer» \tMeiosis is the form of nuclear cell division that results in daughter cells that have one half the chromosome numbers as the original cell.\tIn organisms that are diploid, the end result is cells that are haploid. Each daughter cell gets one complete set of chromosomes, i.e., one of each homologous pair of chromosomes.\tIn humans this means the chromosome number is reduced from 46 to 23.\tThe only cells that undergo meiosis will become sperm or eggs.\tThe joining together of a sperm and egg during fertilization returns the chromosomes number to 46.\tCells that undergo meiosis go through the cell cycle including the S phase so begin the process with chromosomes that consist of two chromatids just as in mitosis.\tMeiosis consists of meiosis I and meiosis II. In meiosis I homologous chromosomes are separated into different nuclei. | |

What is the difference between element and compound |
| Answer» Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H2O) and salt (Sodium Chloride - NaCl). | |

What is the difference between metalloids and alloys |
| Answer» Metalloid: It is actually any chemical element which have the properties just like the mixture properties of metal and non metal. Or Which contain those properties in between the non metal and metal.Mostly the metalloids have the appearance just like the metallic appearance And also they are the brittle one\'s . Boron and silicon are the example.Alloy: They are usually the mixture of metals.Some times mixture of metal may contain another element .They are recognized by their metallic bonding characteristics. Steel as well as the brass is the example of Alloy. | |
