Question o DDT was a highly successful pesticide used in 1940's until its ban in 1972. While highly effective against insects, populations of birds began to decline because of thinning eggshells. On top of that there were concerns about human health. How does the story of DDT show the importance of continued monitoring of ecosystems? O Monitoring is not important as long as a product is thoroughly tested before being released O Monitoring is important to make sure a product is effective O Monitoring is important to ensure a product does not have unintended consequences on an ecosystem O Monitoring is not important because any unintended damage can be fixed when discovered​

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
