Symbiosis or a symbiotic relationship is a close a relationship/interaction between two organisms of different species. The three main types of symbiosis are mutualism, parasitism, and commensalism. Mutualism is the symbiotic relationship where both the species benefits from the other. For example, clownfish live in sea anemones and because of this the clownfish eventually become immune to the paralyzing sting of the sea anemone. The sea anemone gives the clownfish a home and protects the…

Stage 1: What caused the Chicxulub Impactor to enter the Earth’s atmosphere and hit Earth (2) About 65 million years ago an asteroid that is roughly 10 kilometres across, hit Earth on the coast of the Yucatán Peninsula in Mexico. It caused a huge explosion and left a crater that is about 185 kilometres across. This asteroid impact is commonly known to be the reason for the extinction of three quarters of the dinosaurs. (4) The asteroid soared through the sky at more than 40 times the speed of…

Acid Rain is best described as any form of precipitation with high levels of nitric and sulfuric acid. Acid rain or acid deposition is the result of burning of fossil fuels. About two-thirds of SO2 and one-fourth of NOx are released into the air; it comes from electric power generators. These chemicals react would react with water, oxygen, and other substances to form delicate solution of sulfuric and nitric acid to form acidic pollutants. The source of sulphur dioxide comes from volcanoes,…

The Marine iguana which is a reptile is only found on the Galápagos Islands. They are herbivores and feed mostly on the algae on the rocks they lay on near the shore. The males, which are larger than the females, may grow to 4 feet or more. Iguanas seem to prefer rocky shores but may also be found in mangrove swamps and beaches. The iguanas can dive over 9 m down into the water. The lava lizard is a reptile which are native to South America. There are around 20 recognized species but only 7 of…

Populations Lab Study: Ecology in the Galapagos Islands 1. Galapagos tortoises “have a dramatic role in the ecosystem function through herbivory, trampling and seed dispersal” (Blake, S., 2012). Since tortoises are herbivores, they stomp and trample on vegetation grounds. Trampling allows tortoises to open up new places for vegetation to grow on the ground (Discovering Galapagos). Tortoises also play an important role in seed germination for many species such as: the…

Over 75 million acres of planet Earth’s land belongs to the tropical rainforest. (Rainforests Facts the Nature Conservancy) The rainforest is home to many different species, which includes monkeys, snakes, birds, rodents, frogs and lizards. (Earth Floor: Biomes) Many things contribute as threats to this environment. Instead of having such a beautiful and vast area of nature, humans mostly contribute to having it otherwise. The rainforest has much to offer for today’s modern society; everything…

Jared Diamond explores the history of the world from a unique view. An ecologist and evolutionary biologist himself, he was not particularly trained to examine the world in the way an anthropologist would. This book, Guns, Germs, and Steel: The Fates of Human Society, delves into the known world and societies within it, at least as of 1997. Diamond wanted to uncover why history unfolded differently on the different continents over the last 13 thousand years, but more importantly he wanted to…

Identification and characterization of differentially expressed gene(s) in pigeonpea genotypes in response to Helicoverpa armigera infestation Pigeonpea [Cajanus cajan (L.)millspaugh] is an important food legume predominantly cultivated in the tropical and subtropical regions of Asia and Africa almost exclusively as a rainfed crop. It is a diploid (2n = 22), often cross-pollinated crop with a genome size of 833.07 Mbp (Varshney et al., 2012). Globally, it is cultivated on an area of 4.92 M ha…

Can Vegetarians Eat Animal Crackers? When I was growing up meat was always a consistency in the household. It was present in meals almost every day. Weekend mornings brought eggs with sausage and bacon. Homemade chicken soup whenever a family member was under the weather. Holiday meals were notorious in family for being large and celebrated. My favorites included corned beef and cabbage for St. Patrick’s Day, and the turkey and stuffing we had with Thanksgiving dinner. My parents were the type…
