Question 1 What are probable sources of acid precipitation in your community? What impact can this have on the environment in your region? Some of the probable sources of acid precipitation is Fog‚ and rain. During the summer it hardly rains which makes it hard for our crops to grow‚ also since we are in the valley it makes it hard for us to get the water that we need. During the fall it gets very foggy in the mornings and it makes it very difficult to see while your driving. Prevailing

BLAST Lab Assignment A team of scientists having discovered a fossil specimen near Liaoning Province‚ China. Our goal is to observe the physical structure of this fossil and determine the most likely placement of the fossil species in a cladogram. After careful examination of the fossil we notice some traits that could assist us in the classification of the species. For instance‚ it seems to have a vertebrae and what seems to be wing like extensions from its body. We therefore form the hypothesis

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

An activity that primarily utilizes type I muscle fibers is long distance running. Type I fibers are generally slow-twitch fibers‚ meaning they contract slowly and have a high capacity for aerobic glycolysis. Ectomorphs usually perform long distance running. In order to train slow twitch muscles (training slow twitch muscle fibers is for endurance purposes and other aerobic activities)‚ one must increase the time under tension (TUT). Specifically‚ one must focus on doing higher reps (12-15) and low

Background Information LeapFrog Enterprises was founded in 1995 by Mike Wood. Origins date back to 1990 when Mike Wood had an epiphany. He was playing with his 3 year old son and trying to help him recognize letters. It was then Wood came up with the idea of phonemic awareness. Wood took $15‚000 of his own money to invest in a patent. Upon advice from friend he had 20 mothers test the products marketability. Of the 20 mothers‚ all 20 loved the concept. In 1995 LeapFrog Enterprises released their

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality
