What is Monohybrid ratio |
|
Answer» Ratio which is obtained by monohybrid cross is called monohybrid ratio Ratio of monohybrid cross is 1:3 In F1 generation 3:1,and F2 generation 9:3:3:1 \xa0Monohybrid cross is that cross which is made to study the inheritance of a single pair of genes or factors of a character.It is the ratio which is obtained in the F2 generation when a monohybrid cross is made. It is usually 3 : 1 (phenotypic ratio) or 1 : 2 : 1 (genotypic ratio).\xa0 |

What is electropositive element |
|
Answer» Metals All Metals are known as electropositive element Electropositive element An element whose electrode potential is more positive than that of the standard hydrogen electrode which is assigned an arbitrary value of zero. Electropositive elements tend to lose electrons and form positive ions (e.g. the univalent alkali metals Li+, Na+, K+, etc., and the divalent alkaline-earth metals Be2+, Mg2+, and Ca2+). All metals are elecro positive because they loose electrons and hence they gain positive charge |

What is double circulatory system? And why it is important |
|
Answer» It is a type of blood circulation system where blood moving away from the heart is seperated from blood moving towards it. The double circulatory system of blood flow refers to the separate systems of pulmonary circulation and the systemic circulation in amphibians, birds and mammals.All animals with lungs have a double circulatory system. Sp the deoxygenated blood is pumped to the heart in one circuit, whereas the oxygenated blood is pumped to the body in the second circuit.Blood in one circuit has to go through the heart to enter the other circuit.The advantage of a double circulatory system is that blood can be pumped to the rest of the body at a higher pressure. It means blood pumps twice .First: from heart to lungsSecond :from heart to bodyIt is important bcz mammals are constant blood temperature so they require more energy. |

Why red coloud bend least |
|
Answer» Bcz it has longer wavelength than the size of dust particles,smoke,fog, .so it does deviate in the atmosphere . The colour that bends/refracts the least is red. This is due to the fact that out of all colours on the visible light spectrum (itself a part of the electromagnetic wave spectrum) the colour red has the longest/highest wavelength. This leads to it "bending" the least out of all the colours. |

Trace and explain the steps involved in the formation of seed. |
|
Answer» The transfer of pollen grains from anther to the stigma of a flower is called pollination. Now the male gamete enters into the ovary where fusion of male and female gametes takes place. This process is called fertilisation.After fertilisation of ovules various changes take place. The petals, sepsis and stamens are dried and destroyed. Only ovary remains. The ovary contains fertilised ovule. After fertilisation ovary containing a number of fertilised ovules is called fruit. The fertilised and developed ovule is called seed. Hii vishal |

What is themite welding |
|
Answer» When iron oxide reacts with the aluminium lots of energy with molten iron is formed which is used in welding process. This process is called thermite welding.The reaction of iron oxide with aluminium is used to join railing of railway tracks or cracked machine parts. This reaction is known as the thermite reaction. When iron is react with aluminium, then iron,aluminium oxide and heat form.And this iron is used to join the broken railway track and broken machinery. A mixture of ferric oxide ( Fe2O3) and aluminum powder (Al) is called thermite . In thermite welding iron (Fe) is obtained and this iron is used for welding the railway tracks.. the reaction is as follows .............. ... 2Al + Fe2O3 -----> Al2O3 + 2Fe + heat.. this reaction takes place when magnesium ribbon is burnt. |

why non metal does not react with water and acids |
|
Answer» Non-metals will normally not react with water, however, non-metal oxides will react with water to form acids. In this example, chlorine gas will react with water to form hydrochloric acid and hypochlorous acid. Non metals do not react with acids . Usually a metal reacts with acid to produce hydrogen gas while this is not observed with non metals, this is because metals are electro-positive . therefore metals can give electrons to hydrogen which is liberated as hydrogen gas while is not observed with non metals. Because they have a low melting point |
