Free-Fall Lab Assignment Nishad Gothoskar Physics Online Experimental Design: In order to design an experiment to measure free-fall acceleration‚ the researcher must construct a wooden tower with height 10 meters along with a trap door system to release a tennis ball from rest position. In this case‚ the researcher must measure the time the ball takes to free-fall from rest position to the ground. Using this info and the formula: s=vit+ 12at2 s = 10 m vi = 0 m/s The researcher will

SELECTION- a series of rare‚ but beneficial mutations accumulate over time to produce a complex feature where previously there was none • STRUCTURAL ADAPTATION: A characteristic in a plant or in an animal’s body that helps it to survive in its environment. Examples are protective coloration (camouflage) and the ability to retain water. • FUNCTIONAL ADAPTATION: ?? • TAXONOMY- the science of classifying all organisms; taxonomists classify both living and fossil species - TAXON a category used to classify organisms

Plasmid Grant Zarrinmakan‚ Berkley Kruschke‚ Erika Lawrence. Wed/Fri‚ D-Block‚ 12-January-2015 Introduction Transformation is the genetic alteration of a cell resulting from the direct uptake of exogenous DNA from its surroundings. By doing this lab‚ we will answer the essential question: What influences transformation efficiency? Although there are many possible influences‚ our hypothesis is that plasmid has a positive influence. To test this hypothesis‚ we will set up an experiment in which we

AP Biology Lab Four: Plant Pigments and Photosynthesis Abstract: The purpose of this lab is to separate and identify pigments and other molecules within plant cells by a process called chromatography. We will also be measuring the rate of photosynthesis in isolated chloroplasts. Beta carotene‚ the most abundant carotene in plants‚ is carried along near the solvent front because it is very soluble in the solvent being used and because it forms no hydrogen bonds with cellulose. Xanthophyll is found

1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain

Shalacia Gilmore Fall 2012 BIO 1107 Natural Selection Lab INTRODUCTION In the 1850s‚ two scientists by the name of Charles Darwin and Alfred Russell Wallace composed the theory of evolution by natural selection. (1) Darwin characterized several claims needed for natural selection to happen‚ including heritable variation within the population‚ and the presence of more individuals than the environment can support. They also discovered that certain environments favored certain traits. These
