1. The organism that is the cause of this patient’s illness is Legionella pneumpohila, which means the patient has Legionnaire’s disease. Although there are other organisms that can cause similar diseases, it is clear that Legionella pneumpohila is the organism responsible for this patient’s disease. There are several reasons, but the one that stands out the most is that this organism can only grow on buffered charcoal-yeast extract, which is why there was no growth present on the 5% sheep blood…

wetlands may be able to breed with those in the pond, however, after the construction of the road, species in the wetland on the upper side of the road will not be able to breed with those in the pond if they are not able to cross the road safely. Ecological speciation may occur, which is when divergent natural selection drives reproductive isolation causing speciation. Therefore, pond animals will experience their own divergent evolution, and may become phylogenetically different species. For…

cladoselache. Ctenacanths continued development for over a million years. These sharks are identified by their fin spines that are long and cylindrical with comb like ridges. The oceans after the mass extinctions had less fish and lots of open ecological niches. The stethacanthus evolved from these conditions. This shark lived in warm shallow seas and was 2 feet in length. The males had flat topped dorsal fins and enlarged scale on the top of their heads either for courtship purposes or offering…

Starbucks Idea" for which he has set up an innovation competition to make a cup 100% recyclable. But the mechanism can be reversed, causing serious gaming client education tool. Thus, the city of Philadelphia launched Recyclebank to invite more than ecological good citizenship via points totals, challenges or rewards. Today the game online "social" proposed by the marks affects all people and not only teenagers. 55% of the French population is engaged and video games, or 28 million players. Even…

Many things can disrupt and also alter our ecosystems. When you take a look around our environment, most living organisms that you see were introduced primarily by human activity. Most benefactors are due to the disrupts on the ecosystems which comes from invasive species. Invasive species are a non-native organisms (or plant) alien to an ecosystem. These invaders are capable of sweeping across aggressively into a habitat and taking over the resources like food, sunlight, nutrients, water, and…

the idea “that humans must live within the natural environmental limits of our planet denies the realities of our entire history, and most likely the future” (Ellis). His argument can be basically summarized by this statement he makes, “Humans are niche creators. We transform ecosystems to sustain ourselves”…

The study of influenza virus evolution is not new. In fact, humans have been studying influenza viruses since the beginning of the 18th century. Three types of influenza viruses exist: A, B and C. Influenza B is a strain of influenza virus with the ability to cause severe epidemics. Although influenza A and B have similar structure, genome organization, and epidemiology, they have several important differences which imply that their evolutionary dynamics differ. Unlike influenza A viruses,…

A niche is the role or part that an organism plays in it’s specific ecosystem or habitat. An example would be a sunflower. The sunflower inhabits a grassy area and the role that it plays in the area is that it is the producer that gives off energy to the other trophic levels that also inhabit the grassy area. (1) In total, I found 7 different kinds of bacteria in the columns. (2) -In the Controlled Column, I found Cyanobacteria (5) along the top of the column. This bacteria causes the lighter…

Mankind has always been puzzled about what makes us, well us. René Descartes expresses what I feel is the answer, in the phrase "Cogito ergo Sum", I think therefore, I am. Intelligence is what differentiates humans from animals, but also we are intrigued in who is more intelligent. As Howard Gardner says in his book Multiple Intelligences, man has multiple intelligences and each individual can be proficient in only in one. This means that individuals are intelligent in their one way.…

and  Postzygotic reproductive isolation Under Prezygotic reproductive isolation he talks about six factors that hinders reproduction in species resulting in speciation. I. Mechanical isolation- this occurs where the mating organs do not fit. II. Ecological (habitat) isolation- this comes as a result of the same specie living in different environments hence they cannot meet or mate. III. Temporal isolation- this is a result of species being sexually active or fertile at different times hence no…
