but because it can cause hazard for the humans and possibly to the environment‚ the hydrogen peroxide is now as an alternative to replace formalin for a common treatment for parasites (Pedersen and Flemming‚ 2010). Graslund et al‚ 1 (2003) showed that the hydrogen peroxide acts as chemical that served several purposes such as to eliminate bacteria‚ parasite and also algae in shrimp farming. However‚ the hydrogen peroxide still can be hazardous for the health of farmers (Boyd‚ 1999) and also affect

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by

Case Study- Environmental change leads to changes in a species Possums and sodium fluoroacetate resistance Possums‚ from populations with exposure to this vegetation‚ are particularly tolerant to fluoroacetate. However‚ the level of tolerance varies among the different populations of each species‚ depending on the degree to which the toxic plants were present in their microhabitat. The brush-tailed possum (T. vulpecula) from Western Australia was found to be nearly 150 times more resistant

going to talk about how gold is made. I also noticed some physical and chemical changes happening in the video. My first Physical change I saw was when they drill in a certain spot‚ on the rock then they can put the pieces back together and pretend it did not happen because the molecules have not changed in the object‚ you are just breaking them into smaller pieces. So that is why it is a physical change. A chemical change I saw is when there is gold mixed with other materials like silver and etc. But

Motion and Change Motion and Change two physical displacement features that in turn make up all the physical reality. The rotational motion of electrons and nucleus generate the electrical fields that create all the elements known to man. The amount of neutrons and electrons depends on the elements structure‚ for example water is H2O. Water requires one hydrogen atom and two oxygen atoms this mixture combine creates water. Pre-Socratic philosophers attempted to explain the issues regarding issues

Organizational change is usually triggered by relevant environment shift‚ either internal or external‚ that sensed by companies and leads to intentionally generated response (French‚ Bell & Zawacki‚ 2006). This paper will discuss several organization development models.. Theories of Change In order to survive and prosper in a rapid changing environment of business world‚ organization is often required to generate fast response to changes (French‚ Bell & Zawacki‚ 2005).

As time changes‚ communication changes. The skill of handwriting a letter had slowly went away by fast moving time‚ now the email had been a most preferred method of communication. There are varieties of difference in handwritten letter and email messages‚ still are very similar. In the Old aged‚ where social events were more favored‚ handwritten letters were valued. In today’s world‚ email has replaced the old aged of letter writing. While there are many advantages to email‚ the handwritten letter

this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate
