Both sides of the environment should also be exactly the same except for background color. The temperature needs to be kept consistent inside of the tank. To do this, the spiders need to be kept away from windows and housed somewhere there is no incoming cold air. It has been shown that spiders are less active in colder temperatures, so keeping them at room temperature (70°F) is important. Light entering from outside of the tank should also be the same on both sides. To keep this consistent do not place in sunlight, or somewhere that there are shadows. Overhead lights should be used because they will keep the light even on both sides. The lights should remain on 24 hours a day, so the spiders are always able to see the color of the background they are on.

Turgor pressure PP

Thigmonasty is caused by a change in the turgor pressure within Mimosa pudica leaves. Turgor pressure is defined as the force against the cell walls of the plant that is created by the water within the cell contents. This pressure is responsible for keeping the leaves standing up under normal conditions. When this plant is touched, the mechanosensory response begins by activating the contractile proteins in the base of the leaf. These proteins allow the water within the cell to slowly diffuse out which decreases the turgor pressure in the plant and therefore causes the leaves to collapse. Once one single leaf is touched, the adjacent leaves on the branch get stimulated by the motion of the first leaf and close as well. With the lack or excess of water in heat within the 4 environments, the turgor pressure in these leaves may be altered. Through understanding how thigmonasty takes place in Mimosa pudica plants, one can infer how changes in the surrounding environment might affect the plant's nastics movements.

When a water soluble substance, like Vitamin C, is present in the body at higher than threshold

plasma levels, it will be eliminated from the body through urination. The level of the substance

in the body must reach the renal threshold for this to begin to happen. In the case given in this

example, we are dealing with vitamin C which is a water soluble protein that can’t be stored in

the body. If you were to intake too much vitamin C into your body at a given time, then it will

remain in your blood stream until it is eliminated via the kidneys and urinated out of the body.

Taking the vitamins in smaller quantities in timed out intervals will allow all of the vitamins to

be absorbed into the body because the renal threshold will not be reached.

Due to a new retrovirus that is killing domestic dogs at rapid speeds, only one vaccine can be made to save one breed. The Labrador Retriever, one of the most popular and beloved dog breeds, makes the most sense to save for many reasons. The Labrador Retriever does well in a variety of environments and  is known for being an overall good dog. They have a loyal, loveable, and happy personality that any family would be happy to have in their home. They make for good companions and are happiest when they are with you. It is not difficult to please Labrador Retrievers and it is easy to form a meaningful bond with this beautiful breed. Whether it is playing fetch outside or laying next to you on the couch, these dogs love being with you.


Orgo Lab - Benzoin Experiment Discussion Part 4 PP

Submitted by sbrownstein on Thu, 11/01/2018 - 11:55

1,2-diphenylethane-1,2-diol was present and relatively pure in the final product. Yet the percent yield was 14%. This is a lower % yield than expected. This may be a result of impurities due to the incompletion of the reaction, loss of product in transfers, or evaporation. These mistakes could have been avoided if extra time was given to allow the reaction to complete and as few of transfers between glassware were performed as possible. Another possible change that may increase the % yield would be to increase the moles of benzoin in the reagents. Due to the fact that one mole of benzoin reacts with one mole of sodium borohydride and there is 0.2 mmol less of benzoin than sodium borohydride in the reaction, benzoin is the limiting reagent. By increasing the molar amount of benzoin in the reaction, the reaction would produce a larger amount of product yield, ultimately increasing the % yield.


Color Change

Animals have evolved multiple strategies for blending in with their environments, from the iconic color-changing common chameleon (Chamaeleo chamaeleon), to resembling a bundle of floating seaweed like the leafy seadragon (Phycodurus eques). These strategies are englobed in a broader term known as crypsis, and play an important role in predator-prey interactions for both hiding and hunting. One example of crypsis as a predation strategy is the case of the flower crab spider Misumena vatia. This species is capable of hunting relatively large prey such as bees, with the help of its ability to change color between yellow and white.

Addiction to narcotics pp

Submitted by yurigarcia on Tue, 10/30/2018 - 22:23


The deaths for overdose in the next decade will be more than the victims of HVI. There is an actual crisis of addiction of medicines that derivate from opioids in the U.S. This will cause a half a million deaths in the next decade. According to historians, everything changed in January 1980 with the publication of a letter of 101 word in the prestigious “New England Journal of Medicine”, that affirms the addictive capacity of these derivatives in hospitalized patients was negligible. 

As a result, doctors began using narcotics more freely. Then a study suggested that narcotics could be used with few side effects in patients with chronic pain that weren’t in serious conditions. With less fear of its use, doctors were progressively prescribing narcotics to patients with all type of chronic pain. Then in 1996 the laboratory Purdue Pharma started selling Oxycontin. This marked a before and after the crisis of the aggressive marketing practiced of that pharmaceutical companies. 

The American society reacted too late to the narcotics addiction and only last month a law was approved by the senate to control the problem. The use of narcotics in a patient with severe pain is an absolute necessity, but the necessary padlocks must be put in place to prevent their uncontrolled use from ending up causing addiction in innocent people.

PP Dog

The Labrador is the one the most intelligent breeds of dogs on the planet. Their relaxed temperament and ability to learn quickly has proved them to be extremely versatile, yet widely competent dogs. They have an incredible sense of smell, and throughout history have been used for hunting and tracking. Labradors are also known to have the largest litters among any other breed, lending the vaccinated pregnant mother the highest chance to produce the most puppies. Maximizing the output of puppies from a mother is the most logical decision because in order to increase the density of dogs on the planet, the growth rate must be large. In order to maximize the growth rate, we must pick an animal that will grow exponentially while also producing the highest output of puppies in their lifetime.


Impact of studying spider web perfect paragraph

The significance of completing this research is that it will help us to understand more about the variables that affect the thickness of spider webs. Spider webs are a material of interest to people because they are remarkably strong and able to withstand large forces, yet also soft. They vary widely in strength, some have even been said to be able to withstand hurricane force winds.  They have a very high elasticity. Discovering the various factors that contribute to differences in spider web characteristics, such as thickness, could help us learn more about the factors that contribute to their extreme elasticity and could be useful for Material engineering of a material that is both strong and soft.


Golden retriever PP

A new retrovirus has the potential to kill off thousands of dogs breeds across the nation, and it is our duty to determine which dog breed should be saved. I argue that a vaccine should be given to Golden Retrievers because these dogs are a family favorite and should be saved for their wonderful qualities.

A high percentage of dog owning families have Golden Retrievers, making them an extremely popular breed. It would be a shame to kill off a breed that is such common household pet. It makes sense to save a breed that is so common in order to save a high amount of families from feeling despair and mourning. Additionally, these dogs are considered fully grown at the age of one; it would be smart to save a breed that is full grown at an early age so that the virus isn’t killing off a high percentage of puppies. Saving this breed would save the virus from harming a large amount of innocent puppies.

            Additionally, golden retrievers are loveable, friendly, and cuddly, making them a household favorite. Young kids typically think of their family’s pet golden retriever as another sibling, and it would be catastrophic to their emotional well-being to take away a piece of their family. Golden Retrievers are loyal pets; it would be upsetting to put them in danger after seeing how loyal they are to their owners.

            It would make sense to vaccinate Golden Retrievers because they are one of the most common household breeds. They are easy to train and always compatible with strangers. Golden Retrievers have a great sense of safety, and always protect their owners. For example, some Golden Retrievers notice when humans need help when swimming and jump in after them to save them from drowning. Their protective and intelligent qualities make them a smart breed to vaccinate to benefit this planet. Additionally, Golden Retrievers usually have litter sizes ranging from four to twelve puppies. As they are great breeders, the population size of these dogs would flourish due to reproduction.

            While it is unfortunate that dog breeds are being wiped out due to a retrovirus, it is important to distinguish reasons to save one breed over another. The great qualities and characteristics of Golden Retrievers makes them a great choice to vaccinate.
