Liquid mixtures that are transparent are usually solutions, and solutions are homogeneous mixtures. A cell is bigger than an atom, electron, or molecule. How many credits do you need to graduate with a doctoral degree? So, that's why it's so creepy, it's using that cell's machinery to reproduce itself. In the second case the entire virus with the exception of the envelope enters the cell. And so a hemoglobin protein you wouldn't even be able to on this scale, maybe it would be a pixel, if that. Stereoselective syntheses of pentose sugars under realistic prebiotic conditions. Is a molecule bigger than a cell? (c) O3 is an element. Molecules are really, really small. (b) mercury alternative to formaldehyde-based reactions. The chemical name of a compound often consists of more than one word, but many compounds, like water, have common one-word names. Prebiotic amino acids as asymmetric catalysts. (b) water Enveloped viruses are enclosed in a membrane similar to that of the host cell. If a water molecule were on this scale I predrew it, this little thing over here, that's my attempt at drawing a water molecule at this same scale. This sample of potassium dichromate is dissolved in water. dramatically up in size and dramatically up in complexity. If you looked at these scales it would be much much much bigger.
