The Gray Wolf (Canis lupus) The Gray Wolf, a powerful, graceful creature, or also known as the timber wolf, has received a bad rap over time in American history. The wolf has played a big role in literature, religions, and other ideas that has molded the mind of the world to believe that the Gray Wolf is nothing but a vile and heartless animal that only lives to kill. The wolf has not only been perceived as the “Big Bad Wolf” but has also been considered symbolic in ways in relation to…

ADI Predator-Prey Population Size Relationship Lab Report In nature, there are many relationships between organisms. One of these is a predator-prey population size relationship, and more specifically for this investigation, predation. In this relationship, an organism (or organisms) depend(s) on others for food. There is a predator, the hunter, and the prey, the hunted. In this experiment, the predators were the wolves, and the prey were the sheep (the grass could also be considered prey, and…

compensation were then calculated for both lakes (Tale 5). In the 2.5m to 1.7m depth in both lakes, the turbidity and algae growth has demonstrated that indicates so much the depth of compensation, such as the ETI, and can also demonstrate its specific trophic states. The TSIs calculated for each lake demonstrate that Wakefield Pond has to be considered a eutrophic lake, because the TSI is just above the 50’s, while Lake Evelyn has an index of 48. This would be categorising it as a mesotrophic,…

The World is Blue, by Sylvia Earle is about her experiences as a marine biologist and all the sea life she met on the way.

That currently many sea life, has either gone extinct or is in danger of becoming. The first couple of pages, inform the reader on how without the ocean, the earth would not be able to sustain any type of life. Earle also writes about her…

Amyotrophic Lateral Sclerosis: The disease that killed the Iron Horse Diseases do not discriminate between socioeconomic status, race or activity level and has little mercy. Amyotrophic Lateral Sclerosis (ALS), otherwise known as Lou Gehrig’s disease, is such a disease. Nicknamed the “Iron Horse”, famed first baseman for the New York Yankees Lou Gehrig, was one of the first individuals to bring ALS into the forefront of the general populations mind’s, after dying from the disease after being…

contain large amounts of the cytokinin (specifically zeatin), and when the seed germinates, it moves from the endosperm to the root tip where it stimulates mitosis. (Cytokinins, 2016) The hypothesis is that if all other variables are controlled and the levels of treatment are applied to the subjects cohesively, the mustard seeds’ radicle and hypocotyl will grow larger both vertically and horizontally; and therefore the quality of the germinating seed will be higher with the addition of cytokinin…
