It is formed by a facultative, reversible arrest at a specific point in the life cycle in response to external conditions (Cassada and Russell, 1975). Usually at the end of the L2 (or less commonly of the L1) larval stage, under unfavourable conditions such as high-population density, or...
a) Cooking b) Burning c) Rusting d) Crushing e) Igniting Physical Change: A physical change is the one in which there is a change in all the different types of physical properties of a compound. These changes are found to be reversible. Answer a...
