Courtship‚ or sexual selection is a form of natural selection in which a male organism tries to prove his worth to the female organism of the same species. Males do this because they are they must pass on their genes to be successful‚ and females are looking for strong attractive males. Females need to be courted because they want to find a strong suitable male to pass genes onto their children. The courting is different in each species but ultimately females are trying to choose the best possible

Final Draft Solar Energy: Powering Our Future Today nearly half of the world’s energy is provided by petroleum. What began as a cheap and abundant way to provide energy‚ has become expensive‚ environmentally harmful‚ and finite. With population explosions and the demands of modern lifestyles‚ the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050

Are humans able to necessarily break apart from their everyday schedule in order to properly deal with managing their time better‚ and to deal with problems in their schedule as properly as they can? Say there is a human with a schedule‚ and everyday he wakes up‚ brushes his teeth‚ eats breakfast‚ gets ready‚ and then drives to work. Each time takes him 5 minutes to wake up‚ 5 minutes to brush his teeth‚ 10 minutes to eat breakfast‚ and 10 minutes to drive to his place of work. Every day he does
