Answer:
Organisms use various strategies and adaptations to regulate body temperature and metabolism. The organisms control the exchange of heat by various ways which include physiological, behavioural means and by insulation.
The factors which play most important role in the heat exchange regulation between environment and organism are as follows:
- effective temperature difference between organism and environment
- Exposed surface area
- Evaporatory and circulatory changes
<u>Insulation</u> :Another most common method used for heat exchange.Animals who have furs,feathers and fat layers which play significant role in insulation. They are very much important because they reduce heat exchange amount between environment and organism. The most common example is of Cats. They used to curl up their bodies when they want to sleep in cold environment, they tuck their bodies in their paws and legs, and they wasp their tails around their bodies. When organism uses the food and oxygen the body temperature begins to increase, this method is known as metabolic heat production.
You would need data from a large number of people, best from a varied age and gender. For each person you would need pulse rate readings of the person at rest not watching television, watching an unexciting television program and watching an exciting sporting event on television. The pulse rates taken not watching television and watching an unexciting program serve as a control and comparison to eliminate the conjecture that watching any television causes pulse rate to increase. You would also have to be sure that each person is watching a sport that they consider exciting rather than one that you consider exciting, not everyone finds the same things exciting. The larger the body of data you accumulate, the more convincing your argument will be.
Exons, because they are the only coding regions in the DNA.
