The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between REM sleep and memory. I will describe previous research and then investigate how REM and memory are associated in young people and in older people. In some ways‚ the sleep patterns of these two groups are very similar‚ but in some ways they are not. 1a) In a normal brain‚ the period of deep sleep is the first half of sleep and the period of REM sleep is the second half of sleep.

Most of the flowering plants use phytochrome to regulate the time of flowering based on the length of day and night (photoperiodism) and to set circadian rhythms. Besides‚ phytochrome also regulates other responses including elongation of seedlings‚ controlling what shape and size leaves form‚ how many leaves form‚ the germination of seeds (photoblasty)‚ the synthesis of chlorophyll‚ and the straightening
