The principle of use and disuse states that if an animal frequently uses an organ then that organ will grow in strength, and if an animal does not use an organ it deteriorates until it eventually disappears (Strickberger 22). The inheritance of acquired characteristics states that the changes that occur in animals through the principle of use and disuse are passed on to the animal's offspring (Strickber ...

Alternativly Powered Cars

... hybrid cars use the two motors differently, but most of the hybrids use a basic setup. Mostly when the vehicle starts and travels at city street speeds less than 30 miles per hour the electric motor does the greatest amount of the work. As the cars power sources begins to lose some of its energy the backup gasoline engine starts. This function is similar to how gasoline cars work, with the alternator using the engine's power to recharge the battery. After the power supply is replenished the gasoline engine shuts down.

Mid-Oceanic Ridges The mid-oceanic ridges rise 3000 meters from the ocean floor and are more than 2000 kilometers wide surpassing the Himalayas in size. The ...

... is caused by the food chain, for example when a tiger preys on a zebra the population decreases. The increase of the population of a species is caused by the predator when it stops feeding on a species lower than the predator in the food chain.

It is seldom possible to count all the individuals in a given space. Explain one method by which biologists can study population densities without obtaining such d ...
