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…

west and with ocean-front lowlands beyond. Mexico has sweeping deserts in the north, and dense rain forests in the south and east. Mexico also has high mountains and deep canyons in the center of the country. Mexico has a stretch of land called the Yucatan Peninsula juts into the Gulf of Mexico. Mexico is covered…

archaeoastronomy. Archaeoastronomers try to figure out what the ancient people studied, how they studied them, and what they learned. By exploring the ancient astronomy, we hope to learn more about those civilizations. In 1992 a crater under the Yucatan Peninsula. It was first thought that whatever landed here ended the dinosaurs. It indicated that it may have also resulted in the climate change during the ice age. It supposedly changed dramatically during a time period as short as a year. It…

Document 4 goes on to explain, that trade networks ran along the Pacific coastal plain. Document 4 then goes on to say, “The other axis compromised overland route that ran north and south, interconnecting Yucatan, the lowlands, the highlands, and the Pacific plain”. The trade networks also extended to water, that surrounded the area, as seen in document 2. The bodies of water lead to trade, travel and transportation. The trading eventually this lead to the…

All heartbeats consist of a mechanical component and an electrical component. The heartbeat is created by cardiac depolarization caused by electrical currents that induce muscle contraction. The electrical component of the heartbeat begins in the Sinoatrial (SA) Node and its function is to send electrical impulses that stimulate your heart to beat, and these impulses induce the atria to contract. As the atria contract, the impulse moves on to the Atrioventricular (AV) node which leads the…

Elizabeth Rodriguez Professor Marcelo CAS 113A 19 September, 2015 Transnationalism Identity is who you are. Who you identify yourself as. They are many different ways on defining identity and it all has to do within the situation. In this case I define it as, knowing who you are or what something is. Another word that also should be defined is Transnationalism. Transnationalism is going beyond national boundaries and interests. In two class readings that we covered, “Central American…

Melanotan 1 (melanotan) Melanotan I is a synthetic polypeptide which is an analogue of the natural peptide hormone, Apha-MSH (Alpha-Melanocyte stimulating hormone) which naturally occurs within the human body and plays the role of triggering melanogenesis. Melanogenesis is the process by which peptides lead to pigmentation of the skin, hair and eyes, and leads to the tanning process hence it is very essential in the protection of the skin against the harmful UV (ultra violet) radiation which…

The country of Mexico officially gained its independence from Spain in 1821. To understand this specific juncture in the country’s history we must understand the political environment that came before it. Long before Cortes landed on the coast in 1521 in search of gold and silver, the political system of Mexico was organized by Mesoamerican civilizations like the Aztecs, Toltecs, Olmecs, and Mayans. By the time the Spanish arrived the Aztecs had a firm political grasp on most of the region. The…

Humans have been the dominant invasive species on the planet. As they have increased in population, their habitats have invaded the habitats of many native species. As natural habitat decreases, one of two outcomes can occur for the invaded species. One, the extinction of the species in the invaded region, or their evolution of “domestication.” This domestication, or human commensalism, develops as a species continues to breed in a human-occupied territory (Brown et al. 2013). For insects…
