2) [6.2] In Microsoft Excel (I’ve provided an Excel spreadsheet, but you are welcome to use the spreadsheet application of your choice: Google Sheets, OpenOffice, etc.) plot a line graph of your green algae population size data to show how green algae relate to phosphorus input levels. Think about which is the dependent and which is the independent variable. Be sure to label your axes. Copy your completed graph into the

The protein molecules in many foods provide the amino acid building blocks required by our own cells to produce new proteins. To determine whether a sample contains protein, a reagent called Biuret solution is used. Biuret solution contains copper ions. However, the chemical state of the copper ions in Biuret solution causes them to form a chemical complex with the peptide bonds between amino acids (when present), changing the color of the solution. Biuret solution is normally blue, but changes to pink when short peptides are present and to violet when long polypeptides are present.

On Tuesday the 20th of September, a presentation was required of all students to show a video of individual experiments after a week was given on the day of the original assigning. Given the task of performing an experiment in order to become acquainted with the Scientific method, students of Biology 621A were required to record their experimentations in full - providing a question to be answered, constructing a hypothesis, designing an experiment that would aid in the proving (or disproving) of the hypothesis and collecting the data found from the experiment. These would go on to be graded based on their overall presentation quality, and content in regards to the mastery of the scientific method while proving its functionality and existence in scientific experiments no matter how small, while determining factors like independent or dependant variables.

In the modern world, the media plays a massive role in an individual’s life. Whether it be watching the news to gain knowledge about their surroundings or just watching daytime television for amusement, it is no question that watching television is one of the most popular pastimes. With a simple click of the remote, a million shows are available for the viewer to watch. Even though it is convenient, it contributes to a developing problem that only modern humans have come to face: the increasing number of aggressive attitudes and behavior found in children.

1. During the install, the option to sync with NTP (Network Time Protocol) server was checked. From a security perspective, why is it important for a system to keep accurate time?

My science fair experiment is a homemade polygraph test. It will measure the sweat responses to different questions. Throughout the experiment I will be asking questions, first testing, then the actual experiment. It will not be as sophisticated as the polygraph tests that the government has, but it still has the same function and purpose. I will be testing Kole Rodriguez for my experiment.

So my guess was correct again. The blue water did slowly enter the red water.

Weigh a dry 25 mL graduated cylinder on the digital scale. Record the mass in Data Table 5.

He believed environmental experiences also had an influence on the social learning of violence in children. He reported that individuals that lived in high crime rate areas were more likely to act violently than those who lived in low crime areas. He also believed television was a source of behaviour modelling. Today films and television shows illustrate violence graphically. Violence is often expressed as an acceptable behaviour.

Mr. and Mrs. Gaytsoff Hades have contacted me to do experiments on whether or not watching cop-killing videos to close to the television effects their child’s social behavior. Their son, Devilon has had problems fitting in with his peers at school. He also has some odd behaviors such as speaking in made-up ancient languages, performing in satanic rituals, and even performing in animal sacrifices. The parents have been accused of child abuse for allowing Devilon to watch these videos close to the television, but they think that this is not the case. Bottom line, they want me to conclude if watching cop-killer videos too close to the television have any negative influences of behavior. I will be conducting three experiments to test this theory.

3.1. Mass balance of the two-step hydrodeoxygenation products The yields of the pretreated, and hydrodeoxygenative products obtained from the 1st, and 2nd reaction with Amberlyst 36 wet, and Pt/C, respectively, based on the weight of the bio-oil, are shown in Table 1.The yield of each product revealed that the composition of HDO products was affected considerably by the pretreated temperature. In the pretreatment step, 94.8-97.0 wt% of reactant was recovered. The amount of by-product (gas, and char) yielded similar amount at 50-100°C, while the yield of gas, and char increased to 4.0, and 1.2 wt%, respectively, when the bio-oil pretreated at 150°C.

number in order from 1 to 100, the make of the car, the price when new

The purposes of this project were to examine TV violence and analyze how TV violence may influence children’s aggression. In Bandura’s Bobo doll experiment, results showed that children who observed aggressive models toward the Bobo doll were more likely to imitate that behavior than children who observed non-aggressive models. Male children were more likely to imitate the model if they were the same-sex compared to female children. Male children displayed more physical aggression compared to female children. The females were likely to show physical aggression when they witnessed an opposite-sex model perform in an aggressive model group. However, females were likely to show verbal aggression when they witnessed a same-sex model perform in

These results correlate highly with the social learning theory on aggressive behavior. Those exposed to substantial violence and aggression were likely to imitate it later on in life. However, while an observational study can elicit enlightening results, they do not provide much on practical, empirical evidence. What the researchers did was observe behavior exhibited by the individuals they studied; they did not control the amount of violence the individuals were being exposed nor were they preventing others from being exposed to such programming. Thus, this study can not be deemed as an “experiment”. While they tried eliminating the lurking variables that may plague the results of their findings, it would be impossible to eliminate every possible influence other than the television exposure through an observational study.

          Due to violence on television, children become less sensitive to that pain and suffering of others or to become more aggressive to others. It also makes children more fearful to the world around them. (Abelard 1) Viewing habits of children observed for many decades deduced that violence on TV is associated with aggressive behavior, more than poverty, race, or parental behavior. It also reported that a TV show contains about 20 acts of violence an hour.
