Zinc is also present in some denture adhesive creams at levels ranging from 17â34 mg/g [17]. While use of these products as directed (0.5â1.5 g/day) is not of concern, chronic, excessive use can lead to zinc toxicity, resulting in copper deficiency and neurologic disease.
If you're looking to learn about cells with a nucleus, this is the wrong place. Prokaryotes do not have an organized nucleus. Their DNA is kind of floating around the cell. It's clumped up, but not inside of a nucleus. If you want to learn about cells with a nucleus, look for information on eukaryotes. And, once again, a prokaryote is a single cell or organisms that does NOT have organized nuclei.
a prokaryotic cell is a cell that does not have a nucleus or membrance covered organelles. and a a eukaryotic is a is a cell that has a nucleus membrane covered organelles.2 people found this useful. Both Prokaryotic Cells and Eukaryotic Cells have an outer cell membrane.   But, prokaryotic cells do not have membranes around their organelles (inside the cell â¦), whereas eukaryotic cells do.
