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

January 31‚ 2014 Mr. Robinson IB Biology I 2ND Period The Effects of Light on Plant Growth Introduction: Photosynthesis is the process in which plants use light energy‚ water‚ and carbon dioxide to produce food. Plants use the food they make for the growth and for the carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light

Lab 12: Meiosis kimberleigh Lewis Biology 1408-63400 Consider the Concepts Experiment: 1. A common misconception about meiosis appears when students identify which of the two divisions converts a diploid cell into two haploid cells. Meiosis I is the division immediately following DNA replication and replication does not occur again before meiosis II. However‚ meiosis I is the "reduction" division when a diploid cell forms two haploid cells. If the DNA duplicated before meiosis I‚ how

Experiment 8.1 Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its

the p-value was between .05 and .2‚ it is confident to fail to reject the null hypothesis‚ which leads the experimenters to believe that the observed phenotypic ratio does significantly deviate from that expected under the assumption of Mendelian inheritance. In the future‚ exploring more complex animals other than fruit flies‚ such as mammals or reptiles‚ would make this experiment a little more difficult‚ but more interesting as well. Without Mendelian genetics‚ it would be much more difficult to
