Pillbug Lab Report Hypothesis

In this experiement, there were two behaviors kinesis, and taxis, our pillbugs showed taxis behavior in all four types of environments. Introduction: Ethology is the

In the second experiment our hypothesis stated that when the number of males placed in a dish are increased with a (sustained) amount of one female beetle, the time span of the mating process will decrease because the female will have of an option. This hypothesis was not supported because with the trials we preformed the results showed that the different ratio of dishes had a different time span of which they

The χ2 value was 0.012858, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact reliable. In Trial 3, twelve isopods (60%) made the choices of hiding behind the sucrose sponge. The χ2 value was 0.00350342, df was 3 and hence the P value was in between

Provide 4 answers. Tell me why the correct answer is correct and why the incorrect answers are incorrect. 1. This occurs when a researcher fails to reject a null hypothesis that is

Research Scenario A: Question 1: Step 1 selection of test statistics Null hypothesis The null hypothesis is a statement that explains there is no difference between two variables (Salkind, 2013). Using the research question, a

Students started off with a population of ten Skittlefish (skittles) on an orange reef (construction paper). The skittles had varying colors, and the adaptive trait being examined was the ability to blend in with the reef so the predators would not find them. The hypothesis that was thought up was that individuals’ survival was based on their location and coloring. The first year began with two of each color, and 5 Skittlefish were eaten that “year”. The ones eaten were two green, two purple, and one red.

In almost every experiment, there’s an independent and dependent variable, a constant, and a control group. The independent variable in this lab was the coins. The dependent variable was the density. The constant was the amount of water. In this lab, there was no control group .

a. Water boils to produce steam at 100 C (212 F) b. Water produces gas with sodium metal c. Water and oil separate when combined d. Water dissolves sugar 22. In the experiment, students put brine shrimp in water with different concentration of salt and counted the number. Which of the following changes to the experiment will increase confidence in the validity of the result? a. Count the number of dead brine shrimp instead of living brine shrimp b. Add more brine shrimp to the water with the highest salt concentration c.

In this experiment, the question that was asked was, are elephants afraid of mice? The hypothesis is if a mouse is placed near an elephant, then the elephant will be frightened. The experimenters traveled to an African safari to perform the experiment with their test subjects (an African elephant and a white mouse). They hid the mouse in elephant dung and rolled over the dung whenever elephants passed by. At first there was speculation that the elephants might have been startled by the moving dung.

My third hypothesis is that the Member’s Mark will hold the most pennies when it is dry because Member’s Mark is two-ply and appears the thickest. PROCEDURE To prepare for both experiments I will acquire five brands of toilet paper, rubber bands, and a stopwatch from local stores. There is no control group for any of the experiments because I am comparing brands of toilet paper.

On April 6, 2016 at approximately 11:45am, a local police station got a call about a hostage situation at a local pharmacy. When police and medical examiners got to each crime scene, they learned that all of the hostages were given drugs and had overdosed on them. Some of the pills, in powder form, were found near the victims. One of the victims was stable enough to tell the investigators that the power on the floor were the drugs they were forced to take. The medical examiner found out each hostage was given either unknown A or unknown B.

In this experiment, we are testing whether or not the Isopods' have more of a preference for an environment with syrup or with water. The alternative hypothesis we devised is that if the Isopods are placed in between a syrup and a water chamber, then they will go towards the syrup chamber. This is believed because we believe the Isopods may have an attraction to the sweet scent and taste of the syrup. My group and I observed 10 pillbugs behavior over the span of 5 minutes, recording the number of pill bugs found in each chamber every 30 seconds. We fail to reject the null hypothesis because the chi squared value is 3.6 which is less than 3.84 (critical value at .05).

Purpose: The purpose of the experiment was to understand how strong a bessbug by using weights and observing the time the best bug takes to travel to a certain distance. Background Information: The horned Passalus; also known as the Bess Beetle, is widely known beetle that is easily recognized. The Bessbug is a shiny black insect with a hard shell.

The objective is to determine foraging preference of ants by observing and measuring their selection between three different sugar concentrated solutions (5%, 15%, and 30%). The hypothesis is that ants prefer high sugar concentrated solutions than low sugar concentrated solutions. The prediction is that most ants will prefer high concentrated solution (30%) than the less concentrated solution

On my work I will introduce the insects called bedbugs, I talk about their historical significance on humans, their natural life, prevalence, mobility and mortality rate. How to prevent them according to the primary, secondary and tertiary intervention will be shown also. Historical Significance Bed bugs have been biting us since the beginning of recorded time (Usinger 1966). Experts believe that the bugs first parasitized bats and then moved to humans inhabiting the same caves in Mediterranean region (Sailer 1952, Usinger and Povolny 1966).
