principal at the end of each year. Bond B has a maturity of two years and interest promises an annual rate of 8.85% (4.425% every six months). Compounding occurs semiannually; accrued interest is added to the bond’s principal every six months. Bond C matures in two years and promises an annual interest rate of 8.65% (.0237% per day). Compounding occurs daily; accrued interest is added to the bond’s principal at the end of every day (assume 365 days/year). A. Calculate the annual yield-to-maturity

Investigating Vitamin C Background Vitamin C is found in green vegetables‚ fruits‚ and potatoes. It is essential for a healthy diet. The chemical name for vitamin C is ascorbic acid. Ascorbic acid is a good reducing agent and therefore it is easily oxidised. Methods for the detection of vitamin C involve titrating it against a solution of an oxidising agent. Where to start There are several oxidising agents that can be used and a commonly used one is 2‚6-dichlorophenol-indophenol or DCPIP

Hepatitis C is an infectious disease caused by the hepatitis C virus (HCV) that primarily affects the liver. There are different types of hepatitis viruses‚ including hepatitis A‚ B‚ D‚ and E. Among the different viruses‚ hepatitis C is the most serious because it can be chronic and cause severe liver damage. During the initial infection people often have mild or no symptoms. Occasionally a fever‚ dark urine‚ abdominal pain‚ and yellow tinged skin is there. Early on chronic infection typically has

IB Biology Lab – Vitamin C content of food Aim: To compare the vitamin C content of different fruits using the decolourisation of DCPIP from blue to clear as the indicator. • You first need to estimate the volume of a known concentration of vitamin C solution required to decolourise 2 cm3 of DCPIP solution. • Then you need to determine the volume of fruit juice that decolourises 2 cm3 of DCPIP solution. This gives an estimate of the concentration of vitamin C in fruit juice. • This

lives. There have been studies that show that people who are abused by their peers are at risk for serious problems (Murillo C.‚ 2008). These problems include low self esteem‚ stress‚ depression or anxiety and even in the worst cases‚ suicide. Sloane Molloy‚ a guidance counselor at Glynn Middle School‚ states “It can escalate to violence when left unchecked” (Murillo C.‚ 2008). Besides the students the school is also affected by bullying. Many schools are fighting back against bullying. There

Investigating the vitamin C content of fruits and fruit juice Aim: In this investigation‚ I aim to measure and compare whether there is a higher content of vitamin C in a fruit or a juice by measuring the volume of the sample required to decolourise a solution of dichlorophenolindophenol (DCPIP). Introduction: For this experiment‚ I aim to investigate and compare the content of vitamin C in the fruit against the fruit juice. The theory of this method is a titration with dichlorophenolindophenol

The cout object is said to be "connected to" the standard output device‚ which usually is the display screen. The cout is used in conjunction with the stream insertion operator‚ which is written as << which are two less than signs as shown in the following example. -------------------------------------------------

Many people have never heard of C-ASIST and are always amazed to hear what they do for the community. I now have an ‘elevator speech’ prepared for when people ask what it is. I always say “C-ASIST‚ is a non-profit organization that offers a free health clinic once a month to help the underinsured and the uninsured.” People don’t know how it works and how the founders are able to run a free clinic‚ but I explain to them that it is all volunteer based so they do not have to pay anyone that works at

Cytochrome-C Comparison Brief Description: The molecular clock refers to mutations in DNA nucleotide sequence of genes occurring at a constant rate over time. The greater the difference in nucleotide sequence between two individuals of different species‚ the greater the amount of time has passed since they diverged from a common ancestor. The molecular clock helps to provide evidence to support conclusions previously based on comparative morphology and fossil records. Hypothesis: One hypothesis

1.3 C. elegans sensory system C. elegans is a simple multicellular organism‚ and‚ like other animals‚ it constantly perceives environmental cues and elicits appropriate physiological responses. Remarkably‚ this process is achieved with only a small number of neurons. An adult C. elegans hermaphrodite nervous system harbors 302 neurons‚ which have been grouped into 118 distinct classes according to their topology and synaptic connection pattern (Ward‚ 1975 #4;Sulston‚ 1977 #8;Sulston‚ 1983 #9;Ward
