Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
Parthenogenesis is a form of asexual reproduction that results in a viable egg. A good example of this would be the Mexican Whiptail Lizard. The answer would be the last choice, an egg develops without being fertilized.
