Then describe what you expect to see with low and high levels of infestation. A bacterium that has a gene for producing Cry proteins Worth 5 possible points 5. . Titles should be straightforward, informative and fewer than ten words. Artery, Blood, Blood pressure 1614 Words 5 Pages bigger sunhats with a brim facing downward are more effective.
Larva hatch from the eggs. All of the above are correct. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. The female European corn borer moth first lays eggs in June. I think that the fish can handle the amount of Dissolved Oxygen to an extent then the population falls, but then starts to build back up. A stomach poison produced by bacteria b. Bt was then introduced into corn using genetic methods.
The Journal of Agricultural Science. Variables Variables Control of the variables Independent variable State your independent variable and the range, if applicable, and also the number of repeats How will you manipulate your variable? This eliminates the need for the application of a corn borer insecticide. Independent Variable- Dissolved Oxygen Dependent- Fish 5. This decreased spermatophore volume is associated with a decrease in female fecundity and fertility. Inspect 20 consecutive plants in each of 5 areas of the field, picking the first plant of each set randomly. The tip of its abdomen protrudes beyond its closed wings. Carbohydrates are important to our body because we need to use energy.
The composition of male pheromones varies with age. Diffusion is movement of cells from a high concentration, to a low concentration. In case of applied research, testable hypothesis need not be evolved from the theoretical framework but still it is important as it provides a background for understanding the problem researched. In this lab we will make them be a prime example of osmosis, which is a transport mechanism. Question 2: How does seed type affect the length of the stem? Begin with a description of the background information that supports this type of investigation and gradually narrow the focus to your research question and a statement of your hypothesis.
Would it pay to apply the insecticide? European Corn Borer Interactive Lab. The opposite effect was found in homozygous Z males. It provides the conceptual foundation to proceed further with the research. The graph will fill in automatically as you enter the averages that you have calculated. During the winter, the European corn borer stays in its larval stage. Record observations about the gum and the ingredients 3. The number of eggs per egg mass decreases each day.
Also, determine if borers are still present and actively feeding. Instructions to Learners Please complete the Module 1 Virtual Lab, Dependent and Independent Variables, using the instructions within this document and not the Virtual Lab instructions. You might just learn something new; I know I sure did. Variables: Independent Variable: type of food available. Obermeyer Overwintering larvae pupate in the spring, emerging as moths in late May and early June. The radish stem was longer.
Question 1: How does seed type affect when the seeds germinate? The E variant of pheromone has a trans- configuration of hydrogen molecules around its double bond, while the Z variant has a cis- configuration. Parts of the experiment Control Group-water Experimental Group- different foods Independent variable- Type of food Dependent Variable- temperature of water Controlled variables- water temperature of unheated water Materials Stirring. Begin the experiment with no infestation. Boiling, Chemistry, Experiment 834 Words 3 Pages drops and thus reducing income. The European Corn Borer, Pyrausta nubilalis Hübner: A Recently Established Pest in Massachusetts. The purpose of this lab is to figure which one is the monomer and which one is the polymer. Identifying Dependent and Independent Variables Instructions: For each of the following research designs, identify the dependent and independent variables.
Based on the information in Table 2, the patterns I observed were that were 2ppm of Dissolved Oxygen added each time and there was 1 fish less than the amount of Dissolved Oxygen, then 4 fish less, then 3 fish less, then 4 fish less, than 5 fish less. This damage can cause leaves to break at the point of borer entry. These holes become apparent as the leaves grow out of the whorl. Rarely, these moths will live on other grains, , or flowers. My hypothesis was correct based on the outcome of the experiment. As the larvae feed and grow, some may be found tunneled into the midrib of leaves.
The hypothesized relationship can be tested by means of suitable statistical techniques. Randomly select the first plant of each sample set. This moth plagues corn crops in , , , and. Hypothesis: If you chew the gum until the flavors completely gone then the sugar will dissolve and the gum will weigh less. Higher humidity also induces the calling behavior, while desiccation, or drying out, decreases the calling behavior.
