Title: Does the frequency of the bright red blotches of the Nepenthes Gracilis affect it’s ability to lure prey? Introduction: The Nepenthes gracilis belongs to the Nepenthaceae family, a group of monotypic carnivorous plants who use their specialized pitcher-shaped leaves to capture their prey through passive pitfall traps (Bauer, Di Giusto, Skepper, Grafe, Federle, 2012). The adaptation of carnivory in plants is as a result of nutrient-poor habitats in which the fitness of the plants…

then it will contain catechol oxidase. The null being, if it is potato extract, then it will not contain catechol oxidase. The second hypothesis, if it is PTU, then it is a noncompetitive inhibitor can be nullified by the statement, if it is PTU, then it is not a noncompetitive…

gracilis. If the null hypothesis is rejected, then this trait in N. gracilis aids in its adaption by contributing to its fitness and improving its chances of surviving, by increasing the amount of preys captured. Adaptations of lid size combined with nectar glands which attract…

The null hypothesis for this experiment reads a change in the substrate, Catechol, concentration then there will be a change in the rate of reaction. The alternate hypothesis states if there is a change in Catechol concentration then there will be no change in the rate of reaction. To explain the null, if one chooses to change the amount of substrate in each trial then you should expect to see a change in a number of products produced in those trails. I predict that the trials with less…

Survey assessment: The survey part of the experiment produced mostly quantitative data. After analyzing the results of the survey, a few interesting findings to support the hypothesis were found, as well as a few that did not necessarily support it. When asked directly, consumers’ answers overwhelmingly supported the original hypothesis. Displayed advertising for healthy food seemed to have a substantial effect on consumers, due to the large sector of survey respondents who claimed to notice…

Does Rhinoceros hornbill’s casque affect its viability? Introduction The rainforests and tropics near Thailand are home to many species including the Rhinoceros hornbill (Buceros Rhinoceros) (DWA, n.d.). In many tourists’ eyes, one cannot help but be attracted to the unusual horn like bone sticking out of the top of the rhinoceros hornbill’s head. That spectacular horn like bone on top of its head is called a casque (DWA, n.d.). Alexander et al. (1994) discovered that the hollowness of the…

first hypothesis for this experiment is as the concentration of caffeine increases, there will be an increase in the pulsation rate. The null hypothesis is that as the concentration of caffeine increase, there will not be an increase in the pulsation rate. Based on the results, there was a statistical significance with a >95% confidence level in the difference of water and caffeine 10mM. Therefore, the experimental hypothesis is supported by the data and is accepted. The second hypothesis…

associated with age in the section of intimate partner is noted with a single * so we know that p is less than or equal to 0.05. The value associated with the age coefficient (-0.11) is less than the level of significance (0.05). As a result, the null hypothesis can be rejected concluding that the age coefficient is significantly statistically related for the fear of cyberstalking by intimate partner.…

the importance of stomata physiology for plants, and test a hypothesis regarding stomatal density. Stomata are vital to plant function because they let the plant take in carbon dioxide from the atmosphere and release water vapor. Stomata are surrounded by two guard cells that help them open and close in response to their environment. We were given the choice to test either the null hypothesis or the alternate hypothesis. The null hypothesis proposed that there is no difference between stomatal…

variance. According to Sykes, the logic behind the t-test is that we formulate a hypothesis. We can either accept or reject the hypothesis depending on where the t-statistic falls, that is, in the uppermost of lowermost tail of the…
