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.

A plasmid is a strand or loop of DNA that is typically found in bacteria as well as archae (single-cell organisms) and eukarya (organisms of complex cell structure). Plasmids carry only a few genes and exist independently of chromosomes, the primary structures that contain DNA in cells. Able to self-replicate, plasmids can be picked up from the environment and transferred between bacteria. Plasmids are used by their host organism to cope with stress-related conditions. Many plasmids, for example, carry genes that code for the production of enzymes to inactivate antibiotics or poisons. Others contain genes that help a host organism digest unusual substances or kill other types of bacteria. Several characteristics of plasmids make them easy to modify genetically.
