Abstract: In this study of researching animals and their behaviors, demonstrates the behaviors of sow bugs and their likeness to dry vs. moist and light vs. shade preference. The general hypothesis for this experiment was that the sow bugs would prefer the shade vs. the light, and the moist climate vs. the dry climate. In this experiment, six sow bugs were obtained in a petri dish lined with filter paper that was taped to keep the bugs from escaping. Three different trials were completed by first covering half the petri dish with a piece of construction paper and the other half left uncovered in the presence of light. The second trial completed was covering half the filter paper with drops of water to present moisture, and dry on the other half, both in the presence of light.
Lab Write-Up By Daniel Nunez 9/9/13 Title of lab: Pill bug behavior lab Background knowledge: Ethology is the study of animal behavior. Behavior is an animal’s response to sensory input and falls into two basic categories learned and innate (inherited) Problem statement/question: What will happen when pill bugs are placed in an area with one side wet and the other side completely dry? Hypothesis: The pill bugs will move towards the dry side. Test variable: The amount of bugs on each side. Outcome variable: The amount of pill bugs in each side.
Introduction: Sow Bugs, small land crustaceans, have oval bodies with armor like plating, live in humid and cool environments such as logs and leaf litter, and are chosen to be used to test for taxis, movement towards or away from a stimulus. Both chemotaxis, movement in response to chemicals, and phototaxis, movement in response to light, are tested in this experimental procedure. The purpose of this experiment is to test the response of Sow Bugs to a light and a chemical source, showing whether they exhibit taxis to a certain stimulus. Body spray was used because it exhibited all the attributes of a potential chemical substance. It has color and smell and being in a liquid and a gas form.
Title: The Beaks of Finches Purpose: We did this lab to demonstrate how natural selection would occur in the habitat with different kinds of finches. Paragraph: This lab demonstrated natural selection involving finches and their beaks. Seeing as finches use sexual reproduction, there is variation within the species. To illustrate, different finches have different types of beaks which may or may not be helpful when trying to survive. We represented the variation of beaks using tools such as pliers, tweezers, a staple remover, an ice cream scoop, a clothes pin and a baby spoon.
Biology 101 Weezie the Worm By: Carlin McKenzie Introduction My lab team did an experiment on what worms like and dislike being around. A lot of different kinds of wet and dry substances were tested during this experiment like corn starch, dry milk, baking soda, ginger, sand, orange juice, molasses, veggie oil, vinegar, and water. Weezie was evaluated how he liked the substances by neutral, negative, and positive. Neutral being that he didn’t really mind being around it, but he also wasn’t going to close. Positive was when he would go close the substance.
In mutualism both species benefit; in commensalism one species benefits and the other is not affected; and in parasitism the parasite benefits and harms the host. 2. Prokaryotes engage in all three types of symbiosis with eukaryotes, e.g., Rhizobium is mutualistic with plants, bacteria living within the intestines and on the skin of humans are mostly commensal but some are mutualistic, e.g., anaerobic, fermenting, bacteria living within the female vagina create an acidic environment hostile to yeast and other fungi. C. Pathogenic prokaryotes cause many human diseases 1. To be pathogenic, a parasite must invade the host, resist internal defenses long enough to begin growing, then harm the host in some way.
It can be concluded from the observations and records of the 1st experiment that sow bugs prefer to spend more time in and environment that consist of dirt rather than one that consist of sand. From the observations and records of the 2nd experiment it can be concluded that sow bugs prefer an environment with higher levels of illumination rather than one with a lower level of illumination. Introduction Sow bugs also known as woodlice or pill bugs are small round topped insects with 7 pairs of legs. Sow bugs belong to the Class Crustacea other crustaceans include lobsters, crabs, and shrimp. Dr. Jonathan Wright of
labatory #4 | Pill Bug Behavior Lab | BIO 101 | | Jordan Deskins (partners with Adryan Cheeseboro) | 10/30/2014 | Objectives: * Conduct experiments examining the responses of Armadillidiiade (“sow bugs ”) to the environmental factor of texture * Design and conduct an investigation of animal behavior * Develop basic experimental design skills For this experiment we want to determine if “sow bugs” gravitate more towards a rough or soft texture when place into a choice chamber. Pill bug research: Pill bugs are crustaceans, and not insects; they’re related to organisms such as lobsters, and breathe through gills. They also have five sections of hard exoskeleton. Other characteristics of the pill bug are that they
Genetics Lab Report We gathered all of the materials together which consisted of: a microscope, small “worm picks” to pick-up the worms, petri-dishes of C. elegans worms, 2 clean petri-dishes with no worms and a circle of worm “food”, ethanol, and a flame. In the following experiments I hoped to learn what types of c. elegans herm mutations were dominant or recessive by crossing mutations and finding the F1 and F2 offspring. I also want to learn how the breeding of these worms will affect the genotypes and phenotypes of the offspring. Gathering all the materials to the group’s workspace, we took the petri dishes full of the worms and placed them next to the microscope. The first petri dish we placed under the microscope at 37x was the one containing wild-type hermaphrodite offspring.
The main point is that objects can serve many purposes for example a coffee pot holding down a piece of paper. Objects can serve many purposes even though they may have not been designed that way. As we look at the Reed example of the Chimpanzee eating the bugs off of the stick we must really stop and think about this situation and whether this stick is the product of function or complexity. A main problem of the argument that the Reed example testifies against is the idea that design and purpose are linked. The stick just happened to act as a good eating utensil however, had to be pulled out of the ground and forced against its original stance.
