AP Biology Summer Summaries There are many differences between proximate and evolutionary causes and explanations on why we are such easy targets for diseases. The proximate explanations are described by its anatomy‚ physiology‚ and biochemistry. Evolutionary explanations go into detail on what would happen if we didn’t have the genes that cause us to get sick. Proximate causes look for what genes it is made up of and how it works. Evolutionary causes are why natural selection hasn’t eliminated

------------------------------------------------- Enzyme Pre-Lab Harry Kang 9/26/12 1) The purpose of this lab was to determine the rate of enzyme activity under variety of different conditions‚ such as‚ different amount of drops of enzymes and different temperature of water. The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction

Chromatography of Photosynthetic Pigments Abstract In this experiment a process of chromatography was used to separate chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta carotene. When these pigments were obtained they were used to measure the wavelengths by way of spectrophotometer of each and the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how

AP Biology Outline for Behavior Territoriality - behavior of animals that enables individuals to occupy and dominate an area. Territory is an area where one or more individuals defend the area. Thus the two are interpedently interacting with each other to defend the area. Dominance Hierarchies social organizations in which some individuals of the group have adopted a subordinate status to others. The role of this in social behavior is that it shows that the subordinate individuals are depended

Throughout the period 1801-1817‚ the government was ruled by the Jeffersonian Republican party‚ whereas the Federalist Party began to slowly fade away from public view. The Jeffersonian Republican party‚ led by Thomas Jefferson‚ professed to favor a weak central government through the support of more states’ rights‚ "...that the states are independent... to...themselves...and united as to everything respecting foreign nations." (Document A). On the other hand‚ the Federalist Party‚ previously led

1. (a) I‚ III‚ and IV are correct. II is not correct. To explain III‚ de Broglie’s equation states l = h/(mv)‚ so nl = nh/(mv) = 2pi(r). Where: l = wavelength‚ v = velocity of electron‚ n = some positive integer‚ r = distance of electron from center‚ m = mass of electron. Solve‚ get mvr = L = nh/2pi. (b) The current wave mechanical model for the atom states that there are an integer number of wavelengths in every standing integer number (n). 2. (a) The first shell electrons in Lithium are

AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

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
