Answers
Answer:
1.A limb (from the Old English lim), or extremity, is a jointed, or prehensile, appendage of the human or other animal body. In the human body, the arms and the legs are commonly called the upper limbs and lower limbs respectively, to include part of the shoulder and hip girdles.
2.When the soil is saturated with water , soil particles become heavier , the soil and the water separate. This is called loading of soil
3. The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. ... Yet this amount of energy is enormous.
4.Materials like air, water, and clear glass are called transparent. When light encounters transparent materials, almost all of it passes directly through them. ... Translucent objects allow some light to travel through them. Materials like frosted glass and some plastics are called translucent.
