It appeared that that antibiotic had decreased the number of yeast cells. This was an unexpected result science antibiotic were meant to kill off bacteria not yeast. Our hypothesis stated whether antibiotic effect yeast cell cultures. We tested this theory by having a control in which one did not contain antibiotics and another that did contain the antibiotics, then collected yeast from the two cultures and placed them on a hemacytometer collecting chamber. These chambers were to see the yeast cells in a microscopic view and if or if not our hypothesis were true.
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
Mealworm Lab Report Introduction: This experiment was all about mealworms, and what items a mealworm prefers to eat or drink. A mealworm is an arthropod. It grows into a beetle called the Darkling Beetle. Mealworms are really just the larval stage of a beetle’s life cycle. They average at about an inch long and have a hard brownish yellow exoskeleton.
The purpose of this experiment is to test the hypothesis of pen’s ink affect on termite navigation. If this hypothesis is true, termites will follow a pen ink line only, regardless of the color of the pen’s ink. Method On January 13, 2014 three worker termites were taken out of the nest at the Coastal Carolina Community College Biology section and put into a petri dish with a damp paper towel. The initial observation (a termite following a red circle made of ink) was replicated again for a closer look. After obtaining 5 sheets of white computer paper (21.5cm by 28cm), Test 1 was performed.
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.
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.

In this experiment there were main 4 hypothesis made according to each agar plate each with a different types of genes on them. There are two genes that are on the agar plate and not in the solution it is the ampicillin and the arabinose genes. The ampicillin gene (amp) is a gene which acts like an antibiotic that kill the bacteria but when used with the pGLO plasmid it lets it survive because of the ampicillin resistant. The arabinose
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.
