Explain single circulation and double circulation |
| Answer» \tSingle circulationDouble circulationHere the blood flows only once through the heart during one cycle of passage through the body.Here the blood flows twice through the heart during one cycle of passage through the body.\xa0It occurs in fishes.It occurs in all other vertebrates other than fishes.Only venous blood passes through the heartMixed or oxygenated or venous blood passes through heart.This is less efficient as gill capillaries slow down the blood flow, hence the body receives blood at a low pressure which decreases the rate of oxygen supply to the cells.This circulation is more efficient as blood flows at higher pressure (especially in birds and mammals). This increases the rate of supply of food and oxygen to the cell and also rapid removal of wastes from them.\t | |

Explain why all the element of a group have similar chemical properties? |
|
Answer» Chemical Properties are properties which depend on valence electronic configuration of each atom. If the valence configuration is same than the properties of all atom would be same. In the one particular group like group one i.e. alkali metal group have only one valence electron in its outermost shell . Thus every element of group posses same properties . More long Because they contain same number of valence electrons |

Write a note on natural selection.. |
| Answer» Charles Darwin proposed the Theory of Natural selection. Natural selection theory states that the individuals with special traits survive by escaping from the predators to multiply their number while other individuals will perish from the environment. The theory insists on the fact that all living organisms descend from common ancestor by exhibiting variations over along period of time or through generations by generations.The successful variations are carried to various generations through natural selection. | |

How does plants breathe |
| Answer» Green plant respires all the time, day and night. All parts of the plant respire, the leaves, the stem, the roots and even the flowers. During the day, plants photosynthesize more than they respire so more carbon dioxide is used up than produced. A green plant photosynthesizes only in the presence of sunlight. While the sun shines, plants perform photosynthesis. In this process, the plants convert sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch. At night, plants do the respiration and gets energy. In this process the plants burn this stored starch to fuel for continue the growth.The breakdown of this fuel takes place in the cytoplasm and in the mitochondria. The breaking of the C-C bonds of complex compounds through oxidation within the cells, leading to release of considerable amount of energy is called respiration. This energy trapped as chemical energy in the form of ATP. The complete combustion of glucose produces CO2 and H2O as end products along with heart energy. | |
