Introduction- We did an experiment about different types of movements called kinesis and taxis. Kinesis is the change in the speed of movement or the rate of turning which is intensified by a stimulus (Meyer, 2006). Taxis is movement towards or away from a stimulus (Meyer, 2006). We did our experiment using Sowbugs. Sowbugs are also called common rough woodlice. They are ectothermic and elliptical-shaped bodies that are heavily plated with different colors such as grey, deep blue, orange, and albino (Riggio, 2013). Methods- Watch four sowbugs in a 5 tray for four five minutes. We used the focus method to complete the ethogram. Step 1 Results This graph represents the total of movements of 4 Sowbugs did in twenty minutes. The most movement are walking around edge, turn around, climbed, sniffing, and walk across. The least movements were climb on, ride, and …show more content…
Results- This graph shows the amount of time spent in the these areas. This tiny sowbug did much of its time in the light portion of this experiment. The tiny sowbug did the most traveling back and forth from the light and dark areas of the trays. This graph shows the amount of time spent in the areas of light and dark. Just like the tiny sowbug the small one spent most of its time in the light area. The small sowbug was less concerned about being in the dark. Discussion- My hypothesis was not completely supported by the data. Yes sometimes the sowbugs did go into the dark area. They spent most of their time away from the dark area. If they got close to the edge of the dark area they would run away from it. We also noticed that the tiny one was riding on the back of the small sowbug when it went into the dark area. I guess even sowbugs need a buddy when they are frightened. The tiny sowbug was more curious to go into the dark area than the small sowbug. All together they spent the same amount of time in the light
To test the hypothesis the impact of temperature on milkweed bugs, they will be placed in three different temperature conditions. The temperatures include: 10°C (refrigerated), room temperature 22°C and at 28°C. These various temperatures represent the lowered temperatures from the milkweed bugs optimal temperature (28°C). The day and light cycle for these conditions will be 16L:8D. To test the hypothesis of the effect of light regime on development, milkweed bugs were placed in 22°C condition with a 16L:8D cycle and 22°C condition with a 2.5L:21.5D cycle. About 35 milkweed bug eggs will be placed in a clear container for each treatment group.
The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.
Introduction The bean beetle also known as the Callosobruchus maculatus, is an agricultural pest insect from Africa and Asia. That can be found throughout the tropical and subtropical regions. The lifecycle of a bean beetles is quite short an adult been beetle lays their eggs on the external surface of a bean. The larva hatches from the egg burrows from the egg through the seed coat and into the bean endosperm without moving outside the protection of the egg.
Introduction: Isopods are crustacean, which is split into smaller groups, called order. Scientifically Isopoda order is called isopods, which include pill bugs and sow bugs (Crustacean class). Most of the time isopods are mistaken for “bugs” since they look like insects.
Stimulants and Depressants How do stimulants and depressants affect a Lumbriculus worm? These questions are answered with the Lumbriculus worm lab. Stimulants and depressants affect the system in different ways. Stimulants make neurons fire faster, and depressants make neurons fire slower. The nervous system of a Lumbriculus worm is very exposed and visible, so different plants and herbs were tested to see how it would affect the heart rate of the Lumbriculus worm.
The data collected from previous classes had a total of 77 owl pellets that were dissected. Out of the 77 total of owl pellets that were examined, a total of 137 rodents skulls were found in the owl pellets compared to a total of 32 nonrodent skulls that were uncovered in the owl pellet. The data in Figure 1, demonstrates the average total number of rodent skulls compared to average nonrodent skulls found in the final spreadsheet from the total number of owl pellets dissected in each class. On average, the amount of rodent skull prey caught is 1.80 in an owl pellet in a night compared to 0.42 nonrodent prey skulls found in an owl
The Wittig reaction is valuable reaction. It has unique properties that allows for a carbon=carbon double bond to form from where a C=O double bond used to be located. Creating additional C=C double bonds is valuable due to its use in synthesis. The Wittig reaction will allow the synthesis of Stilbene (E and Z) from a Benzaldehyde (Ketcha, 141).
Whereas, Virginia Woolf, however, seems to perceive life as pointless, meaningless, and reveals that life’s struggle with death is inevitable. Woolf personifies the moth by describing the moth as “him” versus “it” in order to showcase the aspect of life of all living things and not just the moth. Wolfe describes the life of a moth flying across a window seal then the second time the moth seemed either “so stiff or so awkward that he could only flutter to the bottom of the windowpane; and when he tried to fly across it he failed”. She then describes watching the moth’s futile attempts to fly across the window only to stop momentarily then to “start again without considering the reason of its failure”.
For Woolf, the moth symbolizes herself. She sees herself and her life in the moth. In the beginning of her essay, Woolf describes day moths as “hybrid creatures.” She herself feels as such because of the societal expectations for women in the 1900’s. Woolf expresses that she cannot be a true writer because she is not a man.
The bessbug had a thorax, abdomen, and head. When the bessbug did not have weights on, it moved fast. The bessbug tried as hard as it could (at times) to get onto the lab table surface and get off the carpet squares. Data: Quantitative Data Qualitative
If the bug walks over to the dry side, as opposed to the wet side, where the bugs are known to be attracted to those conditions, then it will give us the possible theory that pillbugs are communal animals, swayed more by majority rather than their familiar habitat. We will repeat the experiment multiple times to see how many of the bugs can be swayed by the majority, starting with 1, and ending the experiment with 4. Independent Variable: Bugs placed in dry habitat (starting with 9, ending with 6) Dependent Variable: Bugs that move over to the majority's habitat (starting
(page 1). The moth lives his life, as if positivity is the only thing it knows. This creates the moth as an embodiment of life. As the others work in the sun, and appreciate the summers day, the moth flies around, its’s only concern in getting from corner to corner. The moth does not think about
When the book starts the rabbit’s room is very bright but as he goes through and tells everything in his room goodnight and become sleepier and sleepier the room appears to become darker and darker in value. Just like as our eye gets heavy when we get tired and begin to fall asleep, we start to see less and less until we finally begin to slumber and there’s just darkness. The illustrations do an incredible job of showing the darkness taking over the room throughout the course of the story. Rabbit’s room is full of so many unique textures.
1. There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce.
