Solution : The rate of breathing is slower in terrestrial organisms as compared to aquatic organisms. What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration? Where, it is utilized to obtaining energy and repair of old tissues.ġ0.
The villi are richly supplied with blood vessels which transport the absorbed food to each and every cells of the body. Solution : The inner lining of small intestine has numerous finger-like projections called villi which increase the surface area for absorption.
How is small intestine deigned to absorb digested food? Solution : Enzymes break-down the various complex components of food into simple and soluble components so that they can be absorbed easily.ĩ. What is the function of digestive enzymes?
(b) Kills the harmful bacteria present in foodĨ. (a) Make the medium acidic for action of enzyme pepsin. Solution : HCl plays following role in our stomach: What is the role of the acids in our stomach? (d) Chlorophyll from chloroplast of green plants.ħ. Where do plants get each of the raw materials required for photosynthesis? Solution : Distinction between autotrophic and heterotrophic nutrition:Ħ. What are difference between autotrophic and heterotrophic nutrition? Solution : The processes essential for maintaining life areĥ. What processes would you consider essential for maintaining life? Solution : Outside raw materials used for by an organism includes :Ĥ. What are outside raw materials used for by an organism? Solution : All the living organism must have movement at molecular levels along with respiration and other life process like nutrition, respiration, transportation and excretion to be called alive.ģ. What criteria do we use to decide whether something is alive? Solution : As in multicellular organisms, all the cells are not in direct contact with environment, simple diffusion does not meet the requirement of all the body cells.Ģ. Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans? Here all chapter lists with detailed examples for NCERT Solution for Class 10 Science.ġ.
#CHAPTER LIFE PROCESSES CLASS 10 PDF#
NCERT Solutions are accessible in PDF format on Physics. NCERT Solutions for class-10 Science Chapter 6 Life Processes is prepared by senior and renown teachers of Physics Wallah primary focus while solving science questions of class-10 is NCERT textbook, Read the theory of this chapter and try to understand the meaning and then after start writing the questions given in class-10 NCERT textbook for the chapter 6. This experiment demonstrates that our lung exhales carbon dioxide.įor more details, you can visit the related article from Solutions for Class 10 Science chapter-6 Life Processes As a result lime water do not turn milky or takes a lot of effort. Atmospheric air contains very less amount of CO 2. When syringe or pichkari is used, atmospheric air is pushed through the lime water. Lime water reacts with CO 2 to form an insoluble precipitate. This gas is exhaled outside through the lungs. Our body cells produce carbon dioxide through oxidation of food. While when we blow air through syringe or pichkari, it takes a lot of time and effort to turn the lime water milky. When we blow Air through mouth it turns lime water milky instantaneously.
