Sir Isaac Newton was one of the most influential physicists and mathematicians of our past. He is often described as a distinguished scientist who viewed the world from a different perspective and he played an invaluable role developing many of the sciences of the contemporary world. He focused his entire career studying complicated topics such as math‚ alchemy‚ optics‚ and physics. After centuries of studying his life and work‚ some even speculate that Newton was searching for a series of principles

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

forms of infectious diseases. The chemotherapeutic agent works by stopping the bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory. Chemotherapy began in the 1940s and is now a multi-billion dollar industry. Different antibiotics and synthetic drugs all have different modes

pleiotropy is the single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits. Mutation in this type of gene will simultaneously affect more than one trait. An example is phenylketonuria‚ a human disease caused by mutation(s) in a single gene that codes for the enzyme‚ phenylalanine hydroxylase. The disease is characterized by mental retardation and reduced hair and skin pigmentation. List and explain other factors that

Taha Al-Yousif Hooke’s Law Lab Date conducted: September 18th 2013 Partners: Mohammed‚ Liam‚ Ben Nguyen Purpose: The purpose of this experiment is to find the relationship between the stretch of the spring and the attached mass and to verify that this relationship is accurately described by Hook’s Law. Theory: Hooke’s Law states that to extend a spring by an amount (Stretch) from its previous position‚ one needs to add an external force (Mass). Therefore

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special
