Temporary moving from the the stressful habitat to a more hospitable area and return when stressful period is over is known as migration.

Use proper terms for the statements given below. The organism may move temporarily from the strainful habitats to more hospitable area and return when stressful period is over

Stress and pressure are both forces per unit area. T in what respect does stress differ from Pressure?

One of the major gift of modern civilisation is the stress. In the mad race to earn more money and the buy more comforts, we have added stress to our life. We donot have proper sleep and this leads to many disorders and diseases. We have to take sleeping pills from time to time (i) What is the chemical name of the sleeping pills ? (ii) How do they help in reducing stress ? (iii) What is the value associated with these ?

Figure shows the relationship between tensile stress and strain for a typical material. Below proportional point A, stress is directly proportional to strain which means Young's moudulus (Y) is a constant. In this region the material obeys Hooke's law. Provided the strain is below the yield point 'B' the material returns to its original shape and size when the force is removed. Beyond the yield point, the material retains a permancnt deformation after the stress is removed. For stresses beyond the yeld point, the material exhibit plastic flow, which means that it continues to elongate for little increases in the stress. Beyond C a local constriction occurs. The material fractures at D (i.e. breaking point). The graph below shows the stress-strain curve for 4 different materials. Material which is good for making wires by stretching is
