Biology: Research Task and Oral PresentationResearch Task:1.Describe some mechanisms found in Australian fauna to ensure:•Fertilisation•Survival of the embryo and of the young after birthFertilisation is the fusion of haploid sex cells in the action of sexual reproduction. It is often a difficult process as:• careful timing is required: both female and male gametes need to be produced and released at the same time• arrangements need to be made to bring the gametes together• A watery medium is always

Evolution is change over a long period of time. An organism’s characteristics change over time due to its DNA. The DNA determines how an organism looks. The process of evolution is over millions of years. Scientists use fossils‚ embryology‚ comparative anatomy‚ and the biochemistry to get data fro the organisms of their evolutionary histories. For this purpose for doing this lab is to related organisms’ skull evolved or change over time. Fossils are past living remain organism that left behind and

investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group is a group of social theories‚ postulating that primate cognition is a result of complex social interactions between

THE NEW WORLD MONKEYS: THE DWARFING HYPOTHESIS Introduction I will consider support for the dwarfing hypothesis in New World monkeys. Since evolution has shown to result in a general increase in body size‚ the case of reduced body size in the New World primates is quite unusual. To explain the phenomenon‚ the dwarfing hypothesis has been proposed (Martin‚ 1992). The dwarfing hypothesis implies that there must have been selective pressure that favored a reduction in body size. Phyletic

New World monkeys also known as Platyrrhini (because of their flat nose) are classified into 4 families. They are all in the superfamily Ceboidea. The Cebidae include the capuchin monkeys and squirrel monkeys. Members of this group are small monkeys that feed on fruit and insects. The Pitheciidae include titis‚ saki monkeys and uakaris. Most of them are in the Amazon River basin in Brazil‚ although a few species are found in Columbia and Bolivia. Members of this group are small to medium sized monkeys

LTE is the latest standard in wireless communication. Term LTE is referred to Long Term Evolution. It is also referred to as EUTRA (Evolved UMTS Terrestrial Radio Access) or E-UTRAN (Evolved UMTS Terrestrial Radio Access Network). This is the next level of wireless communication.

Their long arms and legs adapt them for living in such regions as lowland jungles and mountainous regions. Humans are classified in the order Primates‚ and family Hominade. Within this family‚ human beings‚ our nearest living relatives‚ the African apes‚ are also placed. Though in some classification standards‚ apes are placed in the family Pongidae.
