In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both

MYP 5 A There are many possible solutions to the problem that we are facing nowadays that is Acid Rain. Acid rain is formed from two main gases that are released in the atmosphere which are sulphur oxide and nitrogen oxide. I will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid rain? I also should say the most important thing that scientists are doing in their labs. Where

CYCLES IN BIOLOGY This essay will give examples of cycles in biology from different scales of magnification‚ ranging from molecular level to populations and ecosystems. Cycles are sequences of events which repeat themselves in the same order‚ one event leading to the next. There are many examples of these in Biology. Cycles can be seen even at a molecular level in the body. An example of this would include the passage of action potentials down neurones in the nervous system. When the cell membrane

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine
