Biology Project Autumn Brown 3rd block Mrs. Stephens More than 2‚000 years ago‚ Aristotle began grouping plants and animals into various categories. Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way

Biology Exam Review Unit One – Biochemistry What is an isotope? Isotope - An isotope is all atoms of the same element that have the same number of protons‚ but they may have different numbers of neutrons in the nucleus. - This means that all atoms with the same atomic number can have different atomic masses. - Because they have the same number of protons and electrons‚ they behave exactly the same in chemical reactions. Radioisotope - The nuclei of some isotopes of an element are unstable

will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid rain? I also should say the most important thing that scientists are doing in their labs. Where acid rain is most effects on which states and does it affect human when we swim in a really high acidic ocean. Acid rain is a mixture of water and gases that have a pH of 5 or lower and it is found in our atmosphere. Acid rain is made

The lab was to include a purpose‚ procedure‚ data/observations‚ all reactions and side reactions written out with qualitative data beneath each product and reactant except H20‚ and a summary. The purpose of this experiment is to observe the qualitative aspects of a series of reactions involving copper. Procedure 1.Measure about 1g of solid copper. 2.Place Cu in Erlenmeyer flask and place flask under fume hood. 3.Add dropwise 15M HNO3 until solid copper is completely reacted. 4.Place flask

A Quick Fix Pill Alcoholism is a problem that affects many people around the world. Although many realise their problem and actively try to fix it with counselling‚ family support‚ and professional rehabilitation facilities‚ 90% of patients fail to successfully stop or even reduce their consumption. However‚ it is usually not ‘them’ but instead their brain that gives in first. What if there was simply a drug that tricked the brain into submission‚ into believing that there was no rewarding effects

Biology Lab Report 7 “Independent Assortment & Dihybrid Cross” 10-22-2013 Biology 202 Introduction: In genetics‚ when crossing a purebred white flower with a purple flower‚ we might expect its offspring to be a blend of both colors. Instead‚ we see that its offspring is purple as well. This is led to be by one trait being dominant over another trait. Gregor Mendel came up with a theory that each member of a pair of homologous chromosomes separates independently

Meghann Kiphart AP Biology Lab Report Number One Mrs. Irvine Introduction: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration. This process with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of
