Natural Selection Experiment

INTRODUCTION Natural selection theory is based upon the guess that allorganisms stimulate more(prenominal) offspring that can brook in an surroundings on account of limited resources. The offspring that can subsist long enough to reproduce can pass on the particular forms of variation to their offspring. While the less favourable or adaptive traits are often lost form the factor pool. In other words, we can say that the environment depart from behind contribute effects on phenotypic characteristics of an organism. In this investigation students will act as the predators, armed with all tensile knives, forks and spoons will try to capture 3 antithetical feast species; kidney beans, black beans, and set forth peas. HYPOTHESIS My venture for the quality of objective which would potential to survive is split peas as they are lower-ranking and more in number, therefore control it harder for the predator (mouthpieces) to obtain. Whereas, the typesetters case o f predate that are less likely to survive is kidney beans, as they are big in surface and easier to grab. My hypothesis is that the type of predator which would likely to win the alimentation competition is the spoon(s), go the knife(s) would be the least to win. is a professional essay writing service at which you can buy essays on any topics and disciplines!

MATERIALS AND METHOD: Students actively participate as one of three predator (either knife, spoon or fork) species as they attempt to capture as numerous feeds/individuals (kidney beans, black beans and split peas) as possible of four prey species. In drift to survive each predator must(prenominal) obtain more food, those who receive less food than 50% of populat ion will die. When time is started, each pre! dator will try to pull in as many beans as possible. At the end of 2 minutes, time is called and the feeding stops. apiece predator counts the no of prey (beans) he/she has picked up. The half(a) predator that picked up the most beans survived, the half who did not die. For the second greneration, the surviving predators (which instantaneously is only half) repeats the same(p) process. The process continues until the third...If you want to get a secure essay, cabaret it on our website:
