DVD+R and DVD+RW formats are supported by Philips, Sony, Hewlett-Packard, Dell, Ricoh, Yamaha and others. DVD+R is a recordable DVD format similar to CD-R. A DVD+R can record data only once and then the data becomes permanent on the disc. The disc can not be recorded onto a second time. DVD+RW is a re-recordable format similar to CD-RW. The data on a DVD+RW disc can be erased and recorded over numerous times without damaging the medium. Note: DVDs that have been made using a +R/+RW device can be read by most commercial DVD-ROM players.
A Behavioral Adaptation is something an animal does-how it acts-usually in response to some type of external stimulus. Examples of some Behavioral Adaptions: 1  What an animal is able to eat. 2  How an animal moves.
The functional definition allows us to identify adaptive traits, while the historical definition allows us to identify adaptations. Adaptive traits are those that increase the fitness of an organism [in a given environment]. Adaptations are adaptive traits that got selected for and remained. To understand the difference: vestigial organs are adaptations, but they are no longer adaptive. In other words, they were adaptive at one point and got selected for, therefore they are adaptations.
