Symbiosis

Discoveries and inventions are not born from nothingness. If necessity were the mother of invention, an apt father would be a combination of curiosity, scientific temperament and research skills. With the firm belief that I possess these skills, I aspire to fulfill my dream of pursuing advanced research in an application-oriented field, by obtaining my Masters degree in Electrical engineering. As a stepping-stone toward this dream, I am pursuing my Bachelor of Technology degree in Electronics &

Betsy Gladden Evolution Case Study #1 Dr. Amanda Duffus The Evolution of Host-Parasite Relationships Since Darwin’s “dangerous” idea in the nineteenth century, the causes and significances of evolution have been investigated unceasingly. One evident example of evolution is between parasite and host relationships, in which host and parasite partners maximize their own fitness, by evolving to reduce the fitness of the other. Parasites are hypothesized to evolve and cause hosts to

Venom You open your eyes. You're not really sure what just happened. The last thing you remember is stepping in some weird puddle of goo accidentally, and then that goo started engulfing your leg with the rest of your body quickly following suit. Looking down, you see that you're still covered in the strange slime. That's when you feel another presence in your mind. It starts communicating with you, explaining that it's an alien organism that was somehow stranded on earth. lt is a symbiote, and

Sula is a book about two girls who grew up in a town called The Bottom. The Bottom was given to slaves from their slave masters but it was a trick. The slave masters gave the slaves a little bit of land and told them that because they were on a hill, they were closer to heaven. There were two girls that lived in The Bottom and despite their differences they grew to become very close. Sula and Nel are the exact example of opposites attract. Nel comes from a stable home and Sula comes from a home

1. A phoretic relationship is when two different species, who benefit from one another, travel together throughout their relationship. An example of phoresis is the species of fly, Dermatobia hominis. The fly attaches the larvae to another insect such as a mosquito and when the mosquito travels and feeds on an animal or human, the eggs hatch and the larvae burrows itself into it’s skin. 2. Mutualism is when both parties of the relationship benefit from the association. Obligatory mutualism is when

Eastern subterranean termites are insects with a well ordered social system whose members are characterized by different castes such as the queen and king for reproduction and the workers who are responsible for building shelter and finding food (Laboratory Manual, 87). When a worker finds a food source it leaves a trail on the ground with its pheromones which acts like a temporary signal, so other workers can follow and find the same food source (Laboratory Manual, 87). Certain pens have chemicals

Biology essay – Relationships and interactions There are many different types of relationships and interactions between organisms. Every organism is in some way connected or associated with another. Some organisms need to depend on other organisms to survive which shows how important some of these relationships or interactions can be in biology. Interaction is a vital part of how many organisms develop over time. Predation is a main example of a relationship between organisms. Predation involves

This past week in Belize was undoubtedly one of the best experiences I have ever had. In the special topics biology class, I learned so much about the ecology, culture, and history of the newly established country. Not to mention, I obtained a new respect for ornithology and a new interest in birds. About the size of Manhattan and with a population of almost 350,000 people, Belize surprisingly holds approximately 500 species of birds. We were able to spot 135 species of birds during our stay and

Often in nature organisms rely on one another to survive. Relationships in which each partner gives equally are called symbiotic. The two partners live harmoniously along side one another depending on each other but still have the ability to stand and act alone should they need to. However, these perfect relationships do not always exist. Sometimes, certain organisms take more than they give and as a result the other organism suffers. Those that do this are called parasites.
