animals - cats‚ rabbits‚ rats‚ dogs‚ monkeys and so many other animals are cruelly used in various kinds of scientific research and millions of them die every year. Is not every life created by God equal? Experimentation on animals serves as a protective alternative to testing on human beings. Since all these new products are being “tested” it seems unlikely and unethical to “test” on human beings right? But since humans are the ones who will later benefit from these products why not have some volunteer

The Black Rat initially originated in Asia during the 14th century. It struck Europe from being carried in by ships‚ slowly spreading to different continents making the Black

tested in this study? (i.e.‚ What is the question that researchers are trying to answer across the two experiment?) (2 pts) The general hypothesis tested in this study concerns the effectiveness of classical moral storytelling as a promoter of virtues in 3- to -7- year-old children. Specifically‚ researchers aimed at determining how this type of fiction might educate children on honesty‚ as well as warn them about the consequences of lying. For this reason‚ they conducted two experiments. In the

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

involves the process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol

of Food Preference in Rats after Initial Taste Preference ---------- --------------- Abstract Rats are animals known to be neophobic‚ fearful of new experiences and tend to show behaviors of avoidance to eat novel foods. However‚ there are high chances that rats will eat novel foods if they have reasons to expect that the food is safe to consume and not harmful. The social transmission of food preference paradigm (STFP) was tested in 28 male rats that were about 5 months old. The

Rats in the Cellar The last thing any homeowner wants to discover is that they have rats in the cellar (basement)‚ especially since the rodents are harbingers of disease. They also cause safety hazards due to their natural gnawing instinct and can chew through electrical wires‚ which can result in the house catching on fire. Norway rats’ habit of tunneling under foundations can potentially cause structural damage to the home‚ causing thousands of repair dollars. Fortunately‚ homeowners have options

A lateral motion device is a mechanism used in some railroad locomotives which permits the axles to move sideways relative to the frame. The device facilitates cornering. The coupled driving wheels on steam locomotives (often simply called "drivers") were held in a straight line by the locomotive’s frame. The flanges of the drivers were spaced a bit closer than the rail gauge‚ and they could still fit between the rails when tracking through a mild curve. At some degree of curvature‚ though‚ the flanges

This idea that perhaps seemingly “good” people can be able to ignore what is obviously morally wrong led me to an article about an interesting experiment: The Milgram experiment. This experiment‚ developed and run by Stanley Milgram‚ took place at Yale University in 1961. Milgram’s experiment consisted of having volunteers from a diverse range of backgrounds and occupations individually brought into a room and sat at a table with an array of levers. Across from this volunteer was another person who

Rats! Most people would only see these little critters as pests. But‚ did you know rats have been domesticated rats for over hundred years. These domesticated rats contribute so many things for the advancement of mankind. Not only are domesticated rats used for research in medical science but they are also kept as pets by many people. Yes‚ pets‚ there are actually people who keep rats as pets. Domesticated rats are great pets for adults and even children. Rats are extremely intelligent pets. They
