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

deficient and that strigolactone application restores the wild-type branching phenotype to ccd8 mutants. Moreover‚ we show that other branching mutants previously characterized as lacking a response to the branching inhibition signal also lack strigolactone response‚ and are not deficient in strigolactones. These responses are conserved in Arabidopsis. In agreement with the expected properties of the hormonal signal‚ exogenous strigolactone can be transported in shoots and act at low concentrations. We

Up until 1750‚ Britain practiced salutary neglect toward their colonies in North America. Although a sense of mercantilism existed‚ Britain’s lack of supervision gave the colonies a chance to govern independently and to develop separately from Britain. Britain’s salutary neglect toward the colonies influenced the development of legislative assemblies‚ commerce‚ and religion by forcing the colonies to become more independent‚ therefore further developing characteristics of and desires to be a sovereign
