<span>I believe the answer is REM alpha sleep. Sleep is a complex biological process that accompany various physiological changes. Normal sleep is usually
classified into non-rapid movement (NRE) and rapid eye movement sleep (REM),
where the stages of NREM are followed by REM sleep. REM alpha sleep is a stage of REM that is associated with unique brain wave pattern such that during REM sleep a sleepers brain waves demonstrate characteristics similar to a walking sleep, a combination of alpha, beta and desynchronous waves.</span>
Each parent contributes one allele for this trait.
The correct answer for the question that is being presented above is this one: "FALSE." <span>Fires are important to savanna ecosystems but not grasslands. </span><span>Well this would be false, considering that savanna are the same as grasslands. More or less they are the same.</span>
Facilitated diffusion
<span>The word 'diffusion' means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs. This is possible due to the structure of the cell membrane. The structure is such that, it allows only certain things to pass in and out of the cell. One such activity that allows selective movement in and out of the cell is the process of facilitated diffusion.</span>
