<span>Both purple and white flowers are recessive phenotypes. In order for an organism to exhibit a recessive phenotype, its genotype must be homogenous for the recessive allele. This is only possible if the parents of the organisms are also purebreeding and they demonstrate the same recessive phenotypes. </span>
<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>
If carbon dioxide and water were abundantly available to a heterotrophic prokaryotic cell, then it would only take sunlight to proceed with photosynthesis to produce carbohydrates such as glucose and other sugars. <span>prokaryotes were recognized as the first organisms that evolved in Earth.</span>

<span>Sewage treatment is also known as wastewater treatment. It is
a process whereby contaminant is removed from wastewater. Thus, chemical,
biological and physical process are commonly used to remove contaminants from
wastewater and the by-products of wastewater treatment is usually inform of
solid waste known as sewage sludge.</span>
