The female wolverine delays implantation; the egg cells float in the uterus for some time attaching to the uterus wall. Delayed implantation means that the young can be born at the right time, from January to April, regardless of when mating takes place. The female produces one litter every two or three years. She digs out a den in a snowdrift, in a tree hollow, or under a rock,

Fishes to Frogs: Respiratory Adaptation Respiration Evolution: Fishes to Frogs The energy needed to sustain life depends on the reduction of oxygen during glycolysis, thereby producing ATP, water, and carbon dioxide. As multicellular organisms began to evolve and grow in size, the ability of the inner-most cells to receive enough oxygen to carry out cellular respiration was compromised. The absorption of oxygen through the outer cellular layers, called cutaneous respiration, evolved

This provided the context for an extreme diversification of fish across the world. Within the evolution of the jaw, there are general patterns of predatory and defense mechanisms, as well as the construct of the armor of modern fish. With the evolution of jaws in fish, there was much less of a need for body armor for protection. Rather, the fish stepped out of the prey position and into a

Physiological Evolution of Fish The anatomy of a typical fish adapted from Moyle, P.B., & Cech, J.J. (1982). How fish has evolved physiologically to become suited to its environment Fishes have been around for utmost 500 million years during which time they have managed to adapt to any type of aquatic habitat. Physiologic features the fish posses that make them more adapted to the environment they live in are not universal to all

Evolution and Adaptation of the Owl Over the years studies have endured to study the owl in its natural environment and in the controlled environment. Much has been found about owls but more can still be learnt. Owls are said to belong to the Aves as their phylogenetic and two distinct families of owls have been pointed out, the Barn owls and the other types of owl. There are 17 known

myth in Daniel Wallace's Big Fish is particularly what allows Edward Bloom to keep other people in his life at a distance. By stretching the events of his life into tall tales, Edward was able to create an identity for himself that was more noteworthy or memorable than the objective facts that typified his existence. However, Edward's son, Will, is called home to reconcile with his father has he
