he ionuwing questions (in about 80 words):Explain why fossil fuels are exhaustible natural resources |
| Answer» <p>Fossil fuelsrequire millions of years to form from the dead vegetation and animals that get buried deep inside the Earth. They require high temperature and pressure for their formation, which cannot be provided in the laboratory.Thus, fossils are limited. Therefore, the use of fossil fuels at this rate will lead to their exhaustion.</p> | |

1. Describe the function of the heart. |
| Answer» <p>The heart is an organ which beats continuously to act as a pump for the transport of blood, which carries other substances with it. The human heart is divided into four chambers. The upper two chambers are called right and left atrium and the lower two chambers are called the right and left ventricles. Right atrium receives carbon dioxide-rich blood from the body. Blood from right atrium enters the right ventricle, which contracts and pumps the blood to the lungs. On the other hand, oxygen-rich blood from the lungs returns to the left atrium. From the left atrium, blood enters left ventricle. Left ventricle contracts and pumps the blood to all parts of the body. Hence, the rhythmic contraction and expansion of various chambers of the heart maintains the transport of oxygen to all parts of the body.</p> | |

\begin{array} { l } { \text { 1. How are fish obtained? } } \\ { \text { 2. What are the advantages of } } \\ { \text { composite fish culture? } } \end{array} |
| Answer» <p>Fish can be obtained by two ways : 1) Capture fishing it is the process of obtaining fish from natural resources. 2) Culture fishery : it is the practice of farming fishes. Farming can be done in both freshwater ecosystem ( which includes river water, pond water ) and marine ecosystem.</p><p>the answer of second question-An advantage of composite fish culture is that it increases the yield of fish. In a composite fish culture, five or six different species are grown together in a single fish pond. Fishes with different food habitats are chosen so that they do not compete for food among themselves. Also, this ensures a complete utilization of food resources in the pond. As a result, the survival rate of fish increases and their yield also increases.</p> | |

Which of the following has morinertia: (a) a rubber ball and astone of the same size? (b) abicycle and a train? (c) a fiverupees coin and a one-rupee coin?1.Cl2. In the following example, try toidentify the number of times thevelocity of the ball changes:A foothall plaier kicks a football |
| Answer» <p>Inertia is the measure of the mass of the body. The greater is the mass of the body;the greater is its inertia and vice-versa.(a) Mass of a stone is more than the mass of a rubber ball for the same size. Hence,inertia of the stone is greater than that of a rubber ball.(b) Mass of a train is more than the mass of a bicycle. Hence, inertia of the train isgreater than that of the bicycle.(c) Mass of a five rupee coin is more than that of a one-rupee coin. Hence, inertia ofthe five rupee coin is greater than that of the one-rupee coin.</p> | |

What part is played by stamens and carpels in reproduction |
| Answer» <p>.Stamens are the male parts of plants and they are made up of long stalks called filaments, at the top of which are present the anthers. .These anthers produce pollen, which is comparable to the sperm in a human male.</p><p>.These pollen migrate through various agents(the most common being wind and insects) and reach the carpels, which are the female parts of a plant(note that some bisexual flowerscan reproduce with themselves, i.e, the pollen from their stamens reach their own carpels). .It's main component is a wideovary at the base of the carpel. It narrows upwards into the style, at the top of which is present the stigma. .The stigma is a sticky platform on which, when insects sit, the pollen stuck to their feet (from various endeavors near stamens) gets transferred to the stigma. The ovary is comparable to the human female ovary.</p><p>It then leads in the formation of sex cells inside the pollen, which travel through the style to the ovary, where they are received by the eggs in the ovary. This eventually leads to the formation of a seed, then a fruit, then a flower, etc.</p> | |
