2. Pentane has the chemical formula C5H12. Pentane is a liquid at room temperature and when mixed with water, it forms a separate layer on top of the water. 1-Pentanol has the chemical formula C5H12O. 1-Pentanol is also a liquid at room temperature, but when mixed with water, it does not form a separate layer. How can the differences in behavior toward water by these two liquids be explained?

the pic attached shows the stages of mitosis. hope it !

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.

not always but somethings can be reproduced in a laboratory.
