Chapter Sources of Energy As we know that our energy requirements increase with our standard of living nowadays. Chapter Management of Natural Resources In Chapter 16 of Class 10 Science , we will learn how to use our natural resources like forests, wildlife, water, coal and petroleum in a sustainable manner. Important Questions on 10th Science Why is respiration considered an exothermic reaction?
Energy in our body is obtained from the food we eat. During digestion, large molecules of food are broken down into simpler substances such as glucose. Glucose combines with oxygen in the cells and provides energy. The special name of this combustion reaction is respiration. Since energy is released in the whole process, it is an exothermic process.
What are olfactory indicators? Give an example. Olfactory indicators are substances which have different odour in acid and base solutions. For example, vanilla essence has characteristics pleasant smell in acid solution and no smell in alkali solution. Platinum, gold and silver are used to make jewellery. Platinum, gold, and silver are used to make jewellery because they are very lustrous. Also, they are very less reactive and do not corrode easily.
Why are carbon and its compounds used as fuels for most applications? Most of the carbon compounds give a lot of heat and light when burnt in air. Saturated hydrocarbons burn with a clean flame and no smoke is produced. The carbon compounds, used as a fuel, have high calorific values. Therefore, carbon and its compounds are used as fuels for most applications. How does the electronic configuration of an atom relate to its position in the Modern Periodic Table?
In the modern periodic table, atoms with similar electronic configurations are placed in the same column. In a group, the number of valence electrons remains the same. Elements across a period show an increase in the number of valence electrons. What is the role of saliva in the digestion of food? Saliva is secreted by the salivary glands, located under the tongue. It makes the food soft for easy swallowing.
It contains a digestive enzyme called salivary amylase, which breaks down starch into sugar. What are the methods used by plants to get rid of excretory products? Plants use completely different strategies for excretion than those of animals. They can get rid of excess water by transpiration. For other wastes, plants use the fact that many of their tissues consist of dead cells, and that they can even lose some parts such as leaves. Many plant waste products are stored in cellular vacuoles.
Waste products may be stored in leaves that fall off. Other waste products are stored as resins and gums, especially in old xylem. Plants also excrete some waste substances into the soil around them.
How does phototropism occur in plants? The movement of plant in response to light is called phototropism. Stem shows positive phototropism as follows: When growing plants detect light, a hormone called auxin, synthesised at the shoot tip, helps the cells to grow longer.
When light is coming from one side of the plant, auxin diffuses towards the shady side of the shoot. This concentration of auxin stimulates the cells to grow longer on the side of the shoot which is away from light. Thus, the plant appears to bend towards light. How does chemical coordination take place in animals? Chemical coordination takes place in animals with the help of hormones. Hormone is the chemical messenger that regulates the physiological processes in living organisms.
It is secreted by glands. The regulation of physiological processes and control and coordination by hormones comes under the endocrine system. The nervous system along with the endocrine system in our body controls and coordinates the physiological processes. How does the process of budding is differ from the process of spore formation? Budding: A bud, as in Hydra, develops as an outgrowth Ncert Solutions For 10th Science With Pdf due to replicated cell division at a specific site.
These buds when mature detach from the parent body and become new individual. Spore Formation: In spore formation, as in Rhizopus, a specific part called Sporangia that produce spores. The spores are covered by thick walls that protect them until a spore gets favourable conditions to grow into a new Rhizopus plant. Explain how sexual reproduction gives rise to more viable variations than asexual reproduction.
How does this affect the evolution of those organisms that reproduce sexually? In sexual reproduction, two individuals having different variations combine their DNA to give rise to a new individual.
Therefore, sexual reproduction allows more variations, whereas in asexual reproduction, chance variations can only occur when the copying of DNA is not accurate. Additionally, asexual reproduction allows very less variations because if there are more variations, then the resultant DNA will not be able to survive inside the inherited cellular apparatus. However, in sexual reproduction, more variations are allowed and the resultant DNA is also able to survive, thus making the variations viable.
Variation and Evolution: Variants help the species to survive in all the conditions. Environmental conditions such as heat, light, pests, and food availability can change suddenly at only one place.
At that time, only those variants resistant to these conditions would be able to survive. This will slowly lead to the evolution of a better adapted species. This is why they need to work hard and keep their interest alive in the subject. Only then will they be able to make sure that they are getting all the benefits of the science stream.
Keeping good marks in school is also really important for that. Students need to understand the chapters and for that, we are always ready to help. We have managed to analyze the different key points that are essential in bridging the gap and we are here to provide the best created and accurate solutions for the class 10 science textbook.
This way, students can get to know what to expect from every single one of the chapters and they will also have an idea about the questions that might be expected in the examination. We have PDF files of NCERT solutions that students can refer to for their study plans and it will surely be a big help to them when they want to be on top of their class. Preparing from these NCERT solutions will ensure that students have deep knowledge about what information is provided in the chapter.
Our answers and solutions are carefully created by professors and masters so students can rely on the accuracy and the details on them. Science is one of the most demanding subjects while still being fun to solve questions. When it comes to explaining, science is the only subject that will not ask you to make assumptions. It will show you why you have to take this formula and solve a particular problem. Once you get a fair understanding of how to solve NCERT solutions, you can easily tackle exemplar books, Previous year question paper , and CBSE sample paper , online mock tests and of course, the most important, your final exams.
You need to keep practicing and revising your performance every day. Science is everywhere; from your child going to school to him riding back home on the school bus, everything has science. A smartphone that a student uses to interact with his friends and distant family members is also a gift of science, and without science, it won't be possible.
