The sky is blue because light scatters off the atmospheric gasses. Light scatter more strongly at the blue end of the the visible spectrum then red.So, looking away from the sun into the sky you see more blue than other colors.
Plasmolysis. Plasmolysis is the contr action of cells within plant s due to the loss of water through osmosis. It is the cell membrane peeling off of the cell wall and the vacuole collapsing. Plasmolysis occurs when a plant cell 's membrane shrinks away from its cell wall. Plasmolysis is an effect of osmosis in plant s. Osmosis is the net diffusion of water across a selectively permeable membrane, such as a cell membrane, from an area of higher water concentration to an area of lower water concentration.

This plasmid can be introduced into a bacterium by way of the process called transformation. Then, because bacteria divide rapidly, they can be used as factories to copy DNA fragments in large quantities. A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA.Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. Plasmids have a wide range of lengths, from roughly one thousand DNA base pairs to hundreds of thousands of base pairs.hen, because bacteria divide rapidly, they can be used as factories to copy DNA fragments in large quantities.
