    produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum concentration for freeze concentration is more than 50 Brix. Membrane concentration can be used for separating components of foods on a molecular basis‚ where the foods are in solution and where a solution is separated

    Aim How temperature affects membranes: investigating the effect temperature has on Beta vulgaris membranes when submerged in a range of different temperatures for one minute. Background Information A cell membrane is made up of a phospholipid bilayer formed by phospholipids that have a hydrophilic head and a hydrophobic tail. The phospholipids arrange themselves in order that the heads are exposed to water and the tails are not thus forming the bilayer. When the temperature increases molecules

    Selective breeding in dogs. Also known as artificial selection‚ is the process by which humans use animal breeding and plant breeding to develop particular traits on the animals such as how they look or to produce certain exaggerated traits. There are many different types of traits that make reason for selective breeding‚ mainly physical‚ and only some for good emotional and disease blocking purposes. In a lot of ways‚ this is similar to inbreeding in humans. Selective Breeding a bad thing because

    effects of stressful experimental treatments on living membranes we are going to examine how fresh beets roots react when they are exposed to different temperatures. Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell 133). They organize specific chemicals and reactions into specific compartments within the cell. Generally‚ cell membranes consist of phospholipids bilayer that is impermeable to

    . Chemistry helps sustain bacteria by protecting the bacteria from outside organisms in the environment out and keeping the bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment
