Perception is often instrumental in the way we perceive things. Many times, people of different morals see the same thing and draw different conclusions. For example, if a doctor were to see an animal testing facility they would likely think of all the lives that were being saved by this facility. If an animal activist were to see the same facility, they would likely think of the suffering endured by the animals inside. Both party’s witness the same thing, yet they draw drastically different…

of most species in the tropics. The stress of bleaching and dying reefs could leach disease and toxins into the ocean. Atmospheric carbon dioxide and methane can lead to decrease in pH, making seawater more acidic and stressful for species of invertebrates and vertebrates. Carbon dioxide has an effect on calcium carbonate buffers in shallower…

The Western Honey Bee and its twenty sub species have been extensively spread across the planet due to economic benefits relating with pollination and honey production. Honey bees live in colonies and split the division of labor among individuals. There are three castes of Western Honey Bees: Workers, Drones, and Queens (Krell 1996). Worker bees are non-reproductive females that make up the largest group in the colony. They specialize in the collection of pollen/nectar and feeding the young.…

Mount Rainier had been freed of the ice a short time later it had developed plant and animal life. Mount Rainier has about 182 species of birds, 14 species of native fish, 5 species of reptiles, 14 species of amphibians, and 65 species of mammals; invertebrates represent about 85% of the animal biomass in the park. It also has more than 890 vascular plants, more than 260 non vascular plants, and more than 100 exotic plants. Mount Rainier is a volcano that can possibly erupt at any time,…

FOXO proteins are conserved from Caenorhabidis elegans to mammals. Invertebrates have just one FOXO protein. It is known as DAF-16 in C. elegans and dFOXO in Drosophila melanogaster (Burgering et al 2002). Mammals have four FOXO proteins- FOXO1, FOXO3, FOXO4 and FOXO6 (Anderson et al 1998, Jacobs et al 2003). The mammalian…

Blanchard’s Cricket Frog (Acris blanchardi) Introduction As humans, we get the opportunity to share and coexist on this planet with some extraordinarily unique and diverse organisms. Of such organisms, reptiles and amphibians are some of the most adaptable organisms on Earth, residing on every continent except bitter cold Antarctica. Here in Minnesota, There are 22 species of amphibians and 31 species of reptiles, ranging from the fast moving salamanders to the slow and nimble turtles. I got…

We learn on the origins of the cell that the theory formulated sais all organisms are composed of cells, and the first living cells was prokaryote and it process the DNA but lack in the nucleus. Fossilized prokaryotes were found in rocks 3.5 billions of years, conditions of the earth were totally different of what it is today, also protocols are cell like structures complete with outer membrane. On the difference between Prokaryotes and Eukaryotes, is that Prokaryotes have smaller cells and…

Ophiothrix spiculata (a.k.a. spiny brittle stars) are the most diverse organisms in phylum Echinodermata that can be found in the ocean all over the world. They are spotted in many different colors such as orange, yellow, red, blue, black, or even tanned with reddish and white bands on their arms. Most spiny brittle stars have either round or star-shape body that are usually not larger than three centimeters. The body is called the central disk which consists of the dorsal shield (aboral side)…
