(२) 'पाणी हेच जीवन !' या विधानासंबंधी तुमचे विचार लिहा.

पाणी हे पृथ्वीवरचे अमृत आहे. ते सर्व सृष्टीचे संजीवन आहे. पृथ्वीवरील सजीव-निर्जीव सृष्टीला पाण्याची अत्यंत आवश्यकता असते. पाण्याशिवाय पशु-पक्षी, प्राणी व मानवी जीवन कोमेजून जाईल. निसर्ग हिरवागार करण्याची किमया पाण्यामध्ये आहे. पाण्यामुळे गाई-गुरांना हिरवा चारा मिळतो. तर पाण्यामुळे मानवाचे अन्नधान्य शेतात उगवते. जगातील प्रत्येक घटकाची तहान शमवण्याचे सामर्थ्य पाण्यातच असते. पाणी नसेल तर ही पृथ्वी भकास, ओसाड व वैराण होईल आणि पृथ्वीवरील जीवन नष्ट होईल. म्हणून 'पाणी हेच जीवन' हा मानवी इतिहासाचा मूलमंत्र आहे.

Give Scientific Reason 

(5) Fibres are one of the important nutrients.

Ans! Fibres are indigestible substance. They are thrown out along with other useless and undigested 2 matter. This aids in egestion. "Some fibres also help in digestion of other substances.

Class 10th science part 2 give scientific reason we feel exhausted after exercising

(4) We feel exhausted after exercising.

Ans. When we undertake constant exercises, there may be shortage of oxygen for the cells. Therefore, our muscles and other tissues perform anaerobic respiration in such condition. In this process, lactic acid is formed. Molecules of ATP produced in oxidation of food are also much less. Thus, there is less energy in the body and accumulation of lactic acid too. All this brings about a feeling of exhaustion.
