AP Biology Lab Report Investigation 12: Fruit Fly Behavior Abstract: In the lab that was conducted‚ students were supposed to examine the tendencies of fruit flies‚ specifically Drosophila’s‚ to move toward or away from important stimuli that aide in their survival‚ also known as taxis. Another objective for this lab was to identify the patterns and relationships between environmental factors and a living organism. Students are supposed to use two bottles to allow the flies to choose

Kunal Bhattacharjee Period 8 AP Bio Enzyme Catalysis Lab Report by Kunal Bhattacharjee 1 Kunal Bhattacharjee Period 8 AP Bio Enzyme Lab Report INTRO: Enzymes are a type of proteins that are formed by Amino acids and help speed up metabolic reactions. They are able to do this by interacting with the substrate . The substrate is what is being breaking down in the reaction. The substrate comes in to contact with the enzyme by binding to

HABITS OF DROSOPHILA MUTANTS Name: Joshua Suidgeest Student ID: U3081023 Tutorial Day and Time: Friday’s at 14:30 (until 17:30) Tutor’s Name: Sandy I declare that the written work presented in this report is my own work. Abstract As a pre-introduction to this lab report as a whole‚ this experiment was carried out to answer some questions that may come to mind when “Drosophila” and “Inheritance” are put in the same sentence. The Drosophila insect is a species of fly of five different

. Information transfer is fundamental to all living organisms. For the three following examples‚ explain in detail how the transfer of information is accomplished. a. The genetic material in one eukaryotic cell is copied and distributed to two daughter cells. Eukaryotic cells go through Interphase and Mitosis. Interphase is further subdivided into 3 stages‚ G1 (first gap)‚ S (synthesis of DNA)‚ and G2 (second gap). In all 3 sub phases cell growth happens and organelles like mitochondria are replicated

Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught

DOLP- Fungi General Structure and Function: For many years‚ fungi were classified into the plantae kingdom because the two kingdoms seemed to be alike; but now‚ we know that they are all too different. In fact‚ the fungi kingdom is more closely related to the animalia kingdom. Some of the only notable similarities between the fungi and plantae kingdoms are that they are both made of eukaryotic cells‚ both immobile‚ both contain cell walls (although made of different material)‚ and both evolved

Chapter 3 Molecules of Life I. Carbon 1. 6 electrons- (4 valence) has the ability to bond with 4 other elements 2. Hydrocarbons- (contains only C & H) 3. Asymmetric carbon- attached to 4 different atoms or groups of atoms II. Isomers - Compounds having the same molecular formula but different structure and properties 1. Structural- differ in covalent arrangement of their atoms and may differ in location of double bonds 2. Geometric- same structure different arrangement 3. Enantiomer/stereoisomer

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle

AP BIOLOGY ESSAY QUESTIONS 1. Discuss the lock-and-key theory of enzyme-substrate interaction giving a specific example to illustrate the theory. Include in your discussion the effects of each of the following: a. b. c. d. 2. Substrate concentration pH shifts Temperature shifts Competitive inhibition Describe in detail the process of meiosis as it occurs in an organism with a diploid chromosome number of 4 (2n = 4). Include labeled diagrams in your discussion. Indicate when and how each of the

The plants used in this experiment are called Wisconsin fast plants‚ due to their extremely short life cycle. In just 40 days‚ the plants germinate‚ grow‚ flower‚ and die‚ which makes them convenient to study in classroom experiments. They are members of the crucifer family and are related to other plants like broccoli and cabbage. In this experiment‚ 8 fast plant seeds were planted in a self-constructed bottle-growing system‚ and they were left to grow for 7-14 days. The Net Primary Productivity
