The Polar Bear and Adaptations The polar bear is seen by many as the beautiful white bear that lives in the cold and ice of the areas within the North Pole. They may never look beyond the beauty to see the animal has progressed through natural selection to become a creature that endures and thrives in the frigid temperatures and prolific ice. The polar bear has adapted in various ways such as temperature regulation‚ hunting skills‚ movement in water and on ice. The bears white coat makes hunting

Cultural Shock and Adaptation Cultural shock is when a person faces many stressors through experiencing new culture‚ and it may lead to psychological crises or social dysfunction. Cultural shock mostly occurs on immigrants (e.g. students‚ business people‚ social change‚ etc). The reaction of cultural shock depends on various factors‚ the experience of other culture adaptation‚ the difference between the home culture and the new culture‚ and the psychological characteristics of the person.

Aerobic - There are three significant adaptations associated with the constant performance of aerobic training. Aerobic training usually produces an increase in functional capacities related to oxygen transport and use in the body. Endurance training produces significant increases in maximal oxygen consumption (VO2max). Maximal oxygen consumption is an indicator of the level of cardiovascular ‚ neuromuscular ‚ and pulmonary functions. Cardiovascular adaptations to this type of training are cardiac

In addition‚ the whales next adaptation is the way the humpback whale gets its air to breathe. a-z-animals.com states that “The humpback whale has not one but two blow holes‚ which are located on the top of the humpback whale’s head.” Finding food‚ this adaptation helps the humpback survive because it allows them to hold more air and then they barely have to swim up to the top of the water. Just as important‚ the glorious creature’s next adaptation is what keeps the whales warm

Chronic Training Adaptations Exercise or training regularly over an extended period of time (3 times per week for 6-8 weeks) leads to the development of long-term or chronic adaptations to training. Evidence of these adaptations can occur at various stages Once achieved‚ these adaptations are retrained unless training ceases. Upon cessation‚ the body will gradually revert to its pre-training condition (de-training). Unlike acute responses to exercises‚ chronic adaptations to training vary

DNA and Genetics in Survival of the Sickest ‚ 2 Environmental Factors that Cause Mutations‚ How Bacteria put under stress can be beneficial for evolution‚ And a Jumping Gene In chapter 6 of “Survival of the Sickest” titled ‘Jump into the Gene Pool” Dr. Moalem jumps into exactly that. Starting us off with the origins of the Vaccine‚ which is quite interesting‚ and then‚ in a very humorous fashion‚ continues into DNA. Dr. Moalem explains to the reader that less than 3 percent of DNA contains

Adaptation is a process of nature in which an animal becomes better suited to its habitat and can be found throughout nature. In vertebrate species‚ these adaptations often affect the skeletal system. One example of skeletal adaptation can be found in locomotion. There is a skeletal adaption called fossorial locomotion which means that animals overtime has modified to allow movement‚ to dig and live underground. These species often have modified limbs to aid in digging‚ as well as‚ compact bodies

mass extinctions over time. Because of the extinctions‚ adaptations appeared‚ more need to evolve became apparent‚ and made it easier to evolve via the climate and environment. The first thing extinctions influenced was adaptations. As stated in the documentary series: Walking with monsters‚ without specific animals‚ the environment changes. As the environments change‚ usually animals do as well. A specific example of this would be the adaptation of early Haikouichthys. Haikouichthys adapted many things

Survival That’s Worth the Cost In life people make hard choices -- difficult choices -- but sometimes to survive people don’t have a choice at all. During “The Cost of Survival” the author talks of two groups of people‚ separated by accountability. The first group of survivors ended up in life-or-death situations because they got the wrong end of the stick‚ so to say. The second group of survivors ended up in life-or-death situations because of risk taking stupidity. People in survival circumstances
