A28 (Biology) (4.6) Proteins are long chains of amino acids that are folded to produce a specific shape that accommodates other A32 (Biology) (4.6) The populations become so different that successful interbreeding is no longer possible. A35 (Biology) (4.6) Through geographical isolation, two populations become physically isolated A34(4.6) A species is group of organisms that can A33 (4.6) Changes to the Environment, New predators New diseases, New Competitors, A catastrophic event, normal speciation

A38 (4.6) Sex cells, e.g. sperm and egg. A37 (4.6) Where a parental cell will use mitosis to form genetically identical offspring. A36 (4.6) Copies of the genetic material are made and then the cell divides into two identical cells. It is needed for growth or repair of cells. A41 (4.6) A small section of DNA. A40 (4.6) Because each gamete is different and when they fuse with another gamete this leads to variety A39 (4.6) Using Meiosis. They only contain one set of chromosomes.
