Explain The Life Cycle Of Silk Moth
Life Cycle of Silk Moth The female silk moth lays about 300 to 400 eggs at a time. The eggs hatch and the caterpillars or silkworms emerge. This is called the larval stage. The silkworm feeds on mulberry leaves. The silkworm secretes fine filaments from two glands on its head. The filaments are made of a protein that hardens to form silk fibres when exposed to air. The … [Read more...] about Explain The Life Cycle Of Silk Moth
What are Metallic and Nonmetallic Properties
What are Metallic and Nonmetallic Properties Metals generally show less electronegative character. In compounds, they generally show a tendency to remain as positive ions. This property is often termed as electropositive character. Metals are electropositive elements. Non metals are generally more electronegative due to their smaller atomic radii. Let us examine the elements … [Read more...] about What are Metallic and Nonmetallic Properties
