It is now possible to make gene constructs in the laboratory by fusing together DNA segments from different sources. For example, genes that encode proteins from a bacteria can be moved into plants to make them resistant to pests without using pesticides. This process of plant improvement has been:

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then returns to earth again as rain. a) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases b) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature increases c) evaporation : temperature decreases; condensation : temperature decreases; precipitation (rain) : temperature decreases d) evaporation : temperature increases; condensation : temperature increases; precipitation (rain) : temperature decreases
