Of equal importance in the functioning of the ecosystem is the evolutionary process‚ which is unique to living organism. Students of environmental biology will learn about the interactions and relationships of the vsrious components of the ecosystem by directly observing the organism in their natural habitat. Observation in the field will be strengthened

    They studied the defense evoked venom of three C. geographus. The significance of their venom is the paralytic toxins‚ which makes the most of this venom. The toxicity of the venom is needed to attack the prey in a high-speed. They also showed a correlation between the size of the animals and the injected venom. Despite their little size and slow-movement‚ they express a defensive mechanism‚ they extend their proboscis and inject the paralytic toxin which is lethal. C. geographus‚ usually hunt during

    around them. It is just the nature’s way of defining the rule “survival of the fittest.” There have been numerous theories on evolution‚ but the one depicted by Charles Darwin in his book On the Origin of Species is observed to be the base of evolutionary biology. Darwin described his scientific theory of how the population evolved by going through the process of natural selection along the generations. In his book‚ he validated how diversity of life evolved from a single ancestor to many different

    Determining Genotypic Frequencies for Alu Insertion Polymorphism at the PV92 Locus Introduction An Alu element is a short stretch of non-coding DNA found in primates. It gets its name from the single recognition site for the endonuclease Alu I‚ located near the middle of the Alu element. Alu elements are transposable DNA sequences that copy and insert themselves into new chromosome locations. They are regarded as “selfish DNA” because they do not encode protein and appear to only exist for their
