Age of the Universe The age of the universe is said to be about 13.75 billion years old. The method used in determining this age would be attempting to find the age of chemical elements‚ oldest star clusters‚ as well as white dwarf stars. Scientists also try to find the universes rate of expansion‚ and behavior of globular clusters‚ which are spherical collection of stars. In order to find this‚ scientists can use radioactive decay to determine how old a given mixture of atoms is in rock samples

The Alps are the youngest and highest mountain system in Europe. They stretch across the western and southern part of the continent in a broad arc. The mountain range startsnear the Mediterranean Seaon the border between France and Italy. Then it curves north- and eastward through northern Italy‚ Switzerland Liechtenstein‚ southern Germany‚ Austria and Slovenia. The Alps are about 1‚000 km long‚ the broadest section over 260 km wide. The highest peak‚ Mont Blanc‚ situated on the border between

Evolution: descent with modification; the idea that living species are descendants of ancestral species that were different from the present-day ones. Biology: the scientific study of life. Emergent properties: new properties that emerge with each step upward in the hierarchy of life‚ owing to the arrangement and interaction of parts as complexity increases. Systems biology: an approach to studying biology that aims to model the dynamic behavior of whole biological systems based on a study of the

Chapter 10 and 11– Homework 1. Describe the stages of transcription. Initiation- Initiator tRNA binds to small ribosomal subunit. Small subunit/tRNA complex attaches to mRNA and moves along it to an AUG “start” codon. Large ribosomal subunit joins complex. Initiation must occur in the order listed above. Elongation- mRNA passes through ribosomal subunits. tRNAs deliver amino acids to the ribosomal binding site in the order specified by the mRNA. Peptide bonds form between the amino acids and

Continental drift is a theory stating that the Earth’s continents have been joined together and have moved away from each other at different times in the Earth’s history. The theory was first proposed by Alfred Wegener in 1912. Whilst his general idea of continental movement eventually became widely accepted‚ his explanation for the mechanism of the movement has been supplanted by the theory of plant tectonics. However there was a problem in accepting this idea originally because Wegener had no convincing

The Paleolithic Diet You see it every day‚ someone goes to grocery store grabs a box of Mac and Cheese some frozen burgers and goes home to make their families dinner for that evening. But what did man do before processed food was available? Even more so‚ what did man do before the agricultural revolution almost 10’000 years ago? The term “Hunter-Gatherer” is almost lost to the modern world‚ something that you only hear about in stories of our past or in fictional recollections. Another question

The Big Bang Theory is the theory that the entire universe was once confined to a dense‚ hot‚ super massive ball then 12-17 billion years ago huge expansions occurred and material in the ball began moving out in all directions. Then‚ instant cooling ensued due to the expansion and thus the universe was born. b. Individuals Roles in the BBT: Edwin Hubble – Created the most powerful telescope of the time
