Education is important to me because it is the key to freedom‚ key to having a better world‚ and the key to enlightening oneself. Education brings freedom to any individual mind who is trap from the cruel circumstances a person faces. The best example is Fredrick Douglas who used education to escape slavery. Education can make the world a better place to live in‚ which it can bring an end to poverty‚ end to racism‚ end of wars‚ and end life threating diseases. Finally but yet importantly‚ education

The presentation should be engaging for the audience (you can direct it to a specific audience or your general community)‚ and should summarize all of the important research and findings. The presentation should include: detailed explanation of how smoke detectors and carbon monoxide detectors work and suggestions for use (number‚ mounting locations‚ etc.) specific explanations of how different fire extinguishers (at least three types) work‚ advantages and disadvantages of each type‚ and effectiveness

Dean Spade challenged my trust in legal reforms and their overall protection for minorities‚ especially those from the LBTQ community. I was ignorantly unaware that a concept such as pink washing existed. Dean Spade explained in the lecture that pink washing was‚ “when an oppressive harmful institution tries to use an emptied-out version of queer politics as a PR stunt for itself‚ but queer people don’t get anything out of it‚” (Spade‚ 2016). One example that Spade used were the Hate Crime Laws and

William ‘Bill’ Shakespeare’s The Tragedy of Hamlet‚ King of Denmark‚ a turn of the 16th century revenge tragedy play‚ is today still a relevant and delving tale‚ that stands as Bill’s reconceptualization of the genre. The genre was popular at the time of Hamlet’s creation‚ and thereby retains traditional elements of a revenge tragedy. However‚ and after adding many dramatic elements‚ a flicker of an Oedipus complex‚ and a touch of humor‚ Bill analyses and explores the revenge tragedy on a more complex

of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a protein network that gives the cake structure. Denaturing of egg white when it cooks is also a chemical reaction (if this does not happen the bread will have not have shape) Baking powder: Baking powder has two chemical reactions which are the following: 1.

proteins are‚ which informs researchers whether there is a ligand binding to the protein or not1. However‚ the point of this lab was to show how light can be used to determine the concentrations of either DNA or proteins in solution‚ which is a very important part of virtual drug screening. This lab introduced how a spectrophotometer can be used to determine the absorbance of different concentrations of a certain solution‚ and then how to use the information gathered and Beer‟s Law to calculate the concentration

reactions‚ a tertiary alcohol‚ such as 2-methyl-2-butanol is most favorable for the reaction because when the leaving group leaves‚ it will leave a + charge on the carbon it was attached to‚ and a tertiary carbocation is the most stable. Another important requirement for a Sn1 reaction is a weak nucleophile attack group. Hydrochloric acid is a weak group because it has no negative charge‚ and works well for the reaction.
