Innate behavior is an unlearned, inherited fixed action pattern, while learned behavior is not inherited but gradually ascertained throughout the life span of a species. Methods and Materials Seven experimental apparatus’ were constructed, like the one in figure 1. Two petri dishes were cut so as to be connected at one end then glued together on a small portion of wood blocking. The petri dishes simulate the testing environment and the connected end allows the specimens to move freely in between scenarios. First the phototaxis experiment was conducted by placing five Armadillidium vulgare in each side of the petri dish for a total of ten in the overall created environment.
Once the three bags were purchased, I separated and counted each color per bag. Other class mates did as well. These results from my sampling and the other class members were compiled into an excel spreadsheet that has been used throughout this project. The average bag of M and M candy (plain) from our class samples has 53-58 pieces of

Why are some organisms unable to grow in potassium cyanide (KCN) broth?if it is sensitive to cyanide, it will be unable to grow in KCN broth * * The ducitol fermentation test is positive when the media changes to a yellow color.
Apparatus For our experiment we used a wooden runway with a start box at one end and we put pieces of plexi glass on top of the runway when the subjects were in it. We also used a bell and a small ceramic bowl with mash and sugar in it. Procedure Surgery The first subject was anesthetized with 1.10 cc, the second with 1.38 cc, and the third with .45 cc of Katamine-Xylazine. Then the subject’s head was shaved and mounted in a stereotaxic frame. An incision was made in the scalp and retracted.
| The Play Years: Piagetian Tasks | Morganne Ausmus | North West Arkansas Community College | In this paper I replicated the four experiments done by Piaget to reveal a variety of deficiencies in the Preoperational thinking of preschoolers. The four experiments consisted of changing the spacing between one row of pennies even though the number of pennies in each row never changed, pouring one cup of water into a different sized container even though the amount of water in each cup never changed, changing the physical shape of a piece of play dough when the amount of play dough doesn’t change, and changing the physical shape of a piece of play dough when the weight of each piece of play dough is equal and does not change. | The Play Years: Piagetian Tasks Piaget’s famous conservation tasks reveal a variety of deficiencies in Preoperational thinking. According to Piaget the Preoperational stage occurs between the ages of two and seven years old and is a time when the thinking of a preschooler lacks the logic of the two remaining stages of development (Berk). Conservation refers to the idea that certain physical characteristics of objects remain the same even when their outward appearance changes (Berk).
This is the reason for hypothesizing that it will have the highest RF value. II. Materials & Procedure Equipment and Materials: * 5 different dyes or inks of the same color (Red) * Sharpie * Crayola Marker * Overhead Pen * Food Coloring Gel * Food Coloring Liquid * 5 Strips of chromatography paper * 5 Test Tubes * 5 mL of water * Pipet * Pencil * Ruler Procedure 1. With the pencil, a mark was drawn at both one and two centimeters from the bottom of the chromatography paper. 2.
Next I placed each of the slides under the microscope from day zero and viewed how many cells were present for each sample. Since each slide held only .5 mL I multiplied by two since the chart called to measure by a full mL. After day one of viewing each type I did the same thing over until I reached day 16 to observe what had taken place.

Introduction The alleleopathy of garlic (Allium Sativum) is a direct or indirect harmful or beneficial effect of one plant. “The smell that produces the cloves of garlic when it’s crushed is produced by volatile, a chemical that evaporates into the air” (college, 2009). The crushed clove garlic smell hinders other plants which keeps them away from competition with the growth of the garlic (Allium Sativum). Other plants other than garlic such as broccoli and carrots have different effects on the environment. In Kingsborough Community College at Biology lab department
The variables in this investigation include the independent variable, which is the environment, the dependent variable, which is the density and diversity of invertebrates and the controlled variables which include the number of vials at each location (10), the spaces between vials (5m), the amount of glycol/ethanol solution used (15ml) and how long the vials are left out (3 days). Materials: - 2x Permanent Markers - 30x Vials - Glycol/ethanol solution - Tape measure - Trowel - 15x petri dishes - 15x tweezers - Magnifying glass - Microscope Method: 1. Divide the class into three groups; with each group looking after a different transect line. 2. Pre-label 10 vials per transect (30 in total).

"Ringworm" is the common name for the skin infection caused by a special group of fungi; it is not caused by a worm at all. The fungi feed upon the dead cells of skin and hair causing, in people, a classic round, red lesion with a ring of scale around the edges and normal recovering skin in the center. Because the ring of irritated, itchy skin looked
