The purpose of this experiment is to observe whether male crickets (Acheta domesticus)1 have a preference between carbohydrates or fat. The null hypothesis is that there is no preference between carbohydrates and fats for male crickets. The expected result is that the male crickets (Acheta domesticus) will prefer the carbohydrates. In this experiment, bananas were used to represent carbohydrates and butter was used to represent fat.
In this experiment, 20 male crickets were selected randomly. One cricket was placed in the choice chamber at a time with bananas in one chamber and butter in the other chamber. The cricket was placed in the holding chamber for 30 seconds before the gates were opened, releasing the crickets. Once the crickets moved out of the holding chamber, the cricket was recorded for a whole minute, noting the time spent in each chamber in seconds. The cricket was then removed from the choice chamber. The same amount of food was replaced (0.75 grams), and the experiment was repeated again for a …show more content…

Our statistical data recorded for the total amount of time that the 20 crickets spent on the butter side was 738 seconds and our average time was 36.9 seconds. The average time was recorded by adding all the trial times for one variable (banana or butter) and dividing by the trial number (20).
If the p-value is less than alpha (0.05), we will reject the null hypothesis that there is no preference for male crickets between carbohydrates and fats. If the p-value is more than alpha (0.05), we fail to reject the null hypothesis that there is a preference for male crickets between carbohydrates and fats. Our p-value was 0.07. Since our p-value is greater than our alpha (0.05), we fail to reject the null hypothesis and conclude that there is no preference for male crickets between carbohydrates and

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).

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

Throughout the duration of the experiment, the female portrayed approximately 14 out of the 51 behaviors observed, in contrast, the male was very active and demonstrated majority of the behaviors observed. It is also important to note that the female was non-responsive and was inactive for the majority of the experiment. The behaviors observed fall under two main categories; either a maintenance behavior or a courtship behavior. The maintenance behaviors observed consist primarily of the crickets grooming in a distinct order, the order consisted of running their antennas through their mouth, followed by running legs through their wings, this entire process lasted a duration of about 60-78 seconds every occurrence. A subcategory of the maintenance behavior could be a foraging behavior, which consisted of the male cricket moving around from one branch to another looking for either food or other resources.

The alternative hypothesis of this data set was that as the amount of methyl eugenol added to the fly increased, so did the number of flies attracted. According to table 3, there was a huge difference of flies in trap 1 where the original group has a total of 39 flies in contrast to 1 fly in the comparison group. However, after comparing the two other traps, although there were more flies captured with 0.50 mg methyl eugenol, the difference was not that significant with a range of 6-7 flies difference in the traps. After calculating the t-test, there was a p-value of 0.3 which was above the indicated range of 0.05 and a critical value of 1.3 which was higher than the indicated value of 1.002 with a degree of freedom of 4. Although the p value was about 0.05, the calculated t value was above 1.002 (vs. 1.3) which could mean that the null hypothesis was rejected.

Experiment 1 was an ecosystem that lacked the presence of a predator whereas experiment 2 had a predator present. We found that experiment 1 displays a positive linear relationship (0.171, adjusted R-squared), but visually has a negative slope in terms of β (-992.1)(see Figure 1), whereas experiment 2 does not return a positive linear relationship (-0.01437, adjusted R-squared), and visually also has a negative slope in terms of β (-964.4)(see Figure 2). Our beta estimates are comparable for the two regressions, but the linear regression for experiment 2 shows a more horizontal line, closer to a slope of zero. Experiment 1 shows a higher mean between our two variables (11.52, F-statistic on 1 and 50 DF), but returns a high probability of a correlation between the Final Concentration of Dunaliella and Number of Artemia (0.001354, p < 0.05) in comparison to experiment two where the data is more closely dispersed from the mean (0.3623 F-statistic on 1 and 44 DF) and lower probability of a correlation between the Final Concentration of Dunaliella and Number of Artemia (0.5503, p >

This meant that in the population there were already ten different color of prey that occurred naturally. However, when the environment was a blue background with colorful flowers and butterflies, many of the different colored prey had gone extinct and the red prey had the highest number of survivors. Also, environment two was pink, white, and black plaid and the prey that had the most number of survivors in that environment was white. This demonstrates that depending on the environment, different variations of a trait would be successful. It also demonstrates that the adaptations in this experiment depended on the environments.

As my experiment, I tested 4 students by giving two of the four students a piece of spearmint gum and two students no gum during the test. The students with the gum both averaged a 97. Georgia scoring and 97, and Chloe also scoring a 97. The students who did not have a piece of gum during the test both averaged a 94. Emma scored a 100 and Mackenzie scored an 88.

Through concise analysis of research papers and other experiments conducted elsewhere, the final conclusion of this lab was supported. All in all, the inquiry experiment allowed the accomplishment of the goal of identifying one of the main reasons why fruit flies eat rotten fruit. Introduction: Drosophila (a model research organism) melanogaster (black abdomen) is the common fruitfly. The lab required the usage of fruit flies as they are a commonly used organism in many experiments. The portion before the inquiry lab utilized the usage of different foods to determine exactly which food the flies would experience more of an attraction towards.

The objective of this experiment is to investigate if Seagulls wait around the bears while they`re finishing to eat their left over. Commensalism is a relationship between two species who live in close association and one receives a benefit (+), whereas the other is unaffected (0). My hypothesis is that the Grizzly bears and the seagulls have a commensalism relationship, where the seagulls receive benefit and the bears are unaffected. I will randomly gather photos from different time frame to look at both the number of seagulls and bears.

This change in portions of a population over time matches Charles Darwin's thoughts on evolution (Millstein 2021), which we aim to evaluate in our experiment. We intend on doing this study by using knives, forks, and spoons to represent plastic claws in an environment and having them compete against one another, having beans as their main resource. We hypothesize spoons will become the dominant trait over generations of natural selection due to it being the best trait to scoop as many beans as possible. Materials and Methods This experiment started with 3 groups, each representing the different phenotypes of plastica. One group was spoons, the second was knives, and the third was forks.

PROCEDURE My experiment was to test if color affects people’s sense of taste. My problem questioned, “Between a yellow sugar cookie and a blue sugar cookie, which cookie will people prefer?”. My hypothesis predicted that people will prefer the yellow cookie instead of the blue cookie because yellow is associated with happiness. To investigate my hypothesis I made cookie dough and then split the dough into two

The preference of food by ants has been studied such as Barbani (2003), studied the food preference and activity of Odorous house ants, and O’Brien (2005) studied the Red imported fire ants and their preference in liquid feeding. It has been seen that ants can as act predators, scavengers, herbivores, detrivores and granivores (Holldobler and Wilson, 1990; Holway et al., 2002) and they choose food which varies in abundance, accessibility, palatability and nutritional value (Goud). The digestive system also plays a role in the type of food to be selected because the intake of food. The digestive enzymes of ants are able to breakdown solid foods and hence most ants prefer liquid sugary food because it easy to digest than the other times of food (Barbani, 2003; Ricks and Vison, 2004). In this will determine ant’s foraging preference when exposed to different sugar concentrated solutions.
