Define evolution and give an example. this is for 12th grade biology

Evolution - The gradual change in a species' inherited characteristics, which is driven by the process of natural selection.

Example: Peppered moth
Prior to the industrial revolution, the moths that had light colour thrived but after, those light coloured moths, died due to them being an easier target as they were a light colour against a dark background (from pollution) so the darker moths survived and were able to reproduce.

Answer from: Quest

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.

Well,what i learned was that unlike many other endothermic reactions, photosynthesis does not absorb energy as heat. instead, during plants absorb energy from sunlight to turn carbon dioxide and water into oxygen and glucose, which is a type of sugar molecule. the energy is stored in the glucose molecules, ready to be used when needed.
