Heat transfer means heat energy is transferred from on object or a body to another. This causes change in many factors, and temperature is one of such factors. If the temperature increases, it means heating is taking place and if temperature decreases it means cooling is taking place.
If Tfinal is more than Tinitial, it means the object has gained some amount of heat energy. Therefore, heating is taking place.
If Tfinal is less that Tinitial, it means the object has lost some heat energy and cooling is taking place.
The answer is : randomization was not used in sample selection. The major difference between experimental and quasi-experimental designs is lack of randomization in sampling selection.
D. A condition that causes narrowing of the coronary arteries so blood flow to the heart muscle is reduced carotid arteries
Thus, light energy is initially converted to chemical energy in the form of two compounds: NADPH, a source of energized electrons ( "reducing power"); and ATP, the versatile energy currency o that the light reactions produce no sugar; that happens in the second stage of photosynthesis, the Calvin cycle.
Hormones are chemical substances that help to regulate processes in the body. Hormones are secreted by glands and travel to their target organs in the bloodstream. Hormones can be used to control human fertility.
