Essay On The Digestive Track Of A Mealworm

A short term effect on an earthworm would be that it would have lots of food for a short amount of time due to

As an experiment I would place multiple kinds of cereal in front of a single mealworm, and record their reactions to each certain type of

In part 2 of the experiment we are inducing RNAi through the process of feeding. To do so, a black pen is used to label the bottom of an OP50 seeded plate with the date and “wild type”. Another OP50 seeded plate is labeled with the date and “dpy-13”. A black pen is then used to label the bottom of the plate seeded with dpy-13 RNAi feeding strain with the date and “wild type”. Five L4-stage worms from the plate of wild type worms are then picked and moved to the OP50 seeded plate labeled “wild type”. Any eggs or young larvae that may have been accidentally transferred are to be picked off of the plate and then flamed in a Bunsen burner. The same method is used to move five L4 wild type worms to the plate seeded with the dpy-13 RNAi feeding strain, and once again to move five L4 dpy-13 worms to the OP50 seeded plate labeled “dpy-13”. These plates are then incubated upside down at 20˚C.

Just last month, a deadly worm was found in not one, but four locations in the U.S. state of Florida. This worm, until recently, was documented in only twenty-one countries, most of which were island nations. Although the New Guinea Flatworm may seem as a highly dangerous predator, it is only about two inches in length and mainly targets snails for its nutrition. These worms are not harmful to humans, but they will feast on any soft creature in the soil. In order to eat snails or any critters with a hard shell, the New Guinea Flatworm latches itself onto the shell’s opening and then spits out its own stomach through the opening in its belly. This allows an acidic goo to dissolve the snail’s flesh and the worm can continue on with its meal by swallowing both its stomach and the snail.

This worm has other things it can eat as well. The one thing this worm loves to eat is the snail eggs it finds when it attaches itself to the bottom of the cabbage leaves and when it is searching for it's prey as well. Many scientists have said that the new guinea flatworm is one of the fifteen tenth largest dangerous and threatening invasion on the united states. They say it continues to grow even this year as well. It fact many people say that when it starts to develop the worms never stop growing and developing and continue to grow and grow and take over populations and specific areas in the united states. Many relationships with other species in the worm occur because the worm continues to invade state by state ,county by county or even area by area and it is causing problems everywhere. Another reason the specific species relationships happen is because the worms continue to have offspring and then they will continue to develop and develop. The next reason is the flatworm can carry a parasitic disease that infects rats and can be passed on to

Purpose: The purpose of the lab is to find out the change in mass of the mealworms and the potato slice and compare them. It is also to find out how much carbon dioxide is in the container at the beginning and the end of the experiment.

There were statistically significant more tail thrashes observed in N2 control worms (M=6.67, SD=1.53) than unc-54 sugar worms (M=2.00, SD=1.00), p=.012, and also unc-54 stevia worms (M = 1.00, SD = 0.00), p=.003. N2 sugar worms (M=8.33, SD=2.08) had significantly more tail thrashes than unc-54 control worms (M=0.67, SD=0.58), p WormBase. N.p., n.d. Web. 15 Apr.

Purpose: We want to see if putting a worm or organism in different temperature will change the rate of CO2. We predict cold will make the process slow down. Hot will speed it up, and with room

Also, using the same technique for Superflab and uncooked rice, concluded the Dmax for Superflab was 4.101x10^-8 and 4.108x10^-8 for uncooked rice. Finally, the average Dmax readings for the green Play-Doh was 4.050x10^-8C (Table 1 and 2). The investigator used solid water as a control to calculate the ratios for each of the bolus materials (Table 3). The One-Way ANOVA concluded differences between the groups (F=523.6, P<0.0001). The average standard deviation between all the samples was

During this experiment many errors were made. The biggest error that was made was that we did not control the environment that the slime molds were in. We initially kept them at school in favourable conditions, where growth was good. We then took them home and moved them around the house, so the slime mold was constantly having to adapt to these environmental changes, until it could not withstand it anymore, and eventually died. Another error that was made was the fact that in transferring the slime molds, and feeding them we used only inoculating hoops, these inoculating

During the 7-day confinement period that occurred prior to the second experiment, two individuals from the control group died due to desiccation. Thus, the control group in the second experiment has a sample size of 4 instead of 6. The individuals that died were then replaced by two new individuals prior to population density manipulation for the third experiment.

One of these is the amount of food. As the Artemia Salina population decreased, the amount of food placed into the beakers daily did not decrease proportionally, so that nearing the end of the experiment, the Artemia Salina were severely overfed. This could have affected the mortality rate. Another area where the experiment could have been conducted improperly is in the cleanliness of the tank. We did not have a filter or an aerator in any of the enclosures, which created a suboptimal environment for the Artemia Salina to live in, which could have contributed to the lifespan of the Artemia Salina.

“It’s mouth was some eighty meters in diameter…with crystal teeth with the curved shape of crysknives glinting around the rim…the bellows breath of cinnamon” (Herbert 225). Simply delineates the monstrosity of these brobdingnagian creatures. And he also says, “ Worms of more than four hundred meters in length have been recorded by reliable witnesses, and there's reason to believe even larger ones exist." (Herbert 356). This gives a glimpse of how truculent the worms can be, and given the fact that the climate provides a tough environment, the worms can be connected to the climate, because if the climate was not so cruel, and hot, then more precipitation would occur on the planet, and water is poisonous to the worm. Worms would cause drastic change to society if they were to ‘disappear,’ because the worm’s feed on Sand Plankton, and sand plankton eat the mélange in the sands of Arrakis. The term “Little Makers” makes its appearance when the sand plankton grows, and become little makers, because they make mélange. This leads to how important the sandworms really are. The Fremen are dependent on the worm, because of the spice that the little makers make. And the Fremen are dependent on the spice, or they will die. So, if the climate were to pose a death sentence for the worms, there would be a deadly process of what would follow: precipitation occurs, and the worms, and little makers would start to die. This would then cause the creation, and distribution of mélange to

There was no significant (p&lt;0.05) difference between the initial weights of the lugworms in the 4 sample groups, avoiding any bias in treatments. As Figure 4 shows each sample group showed a large increase in weight after exposure to the diluted salinities with the lugworms that were placed in full strength seawater not showing an increase of more than 1.7%.

Copepods are good bio indicators of the aquatic ecosystem as their presence can depict the quality of water in aquatic ecosystem. The death of Copepods in week 3 can be due to various factors such as enormous increase in the salinity of the water from 223 to 257 and the temperature wasn’t high enough (optimum temperature 28degree Celsius).(Rhyne et al 2009; Nielsen et al 2003) Copepod existence did not increase when there was rise in salinity and temperature as they were not able to tolerate warm and saline environment. (Hall and Burns 2001) The increased salinity levels generated osmotic stress which copepods couldn’t tolerate. Also, the small aquatic ecosystem in the jar didn’t give enough space for copepods to escape from predators such as Crayfish as predicted by the food web. There wasn 't enough diversity in diets for copepods to feed on so they were unable to acquire their vital nutrients which could have also contributed to their death. However, the death of copepods enabled primary producers to grow which was vital for the survival of the ecosystem as animals need oxygen gas for respiration and energy as they are unable to make their own food.
