salty water and feed on fish‚ carrion‚ plants‚ and detritus. Because they are completely aquatic‚ they rely on their gills for breathing‚ but can spend short periods of time out of the water if their gills will not dry. Like most crustaceans‚ they have a hard‚ calcified exoskeleton. The heart is located in the upper portion of the cephalothorax‚ which is located just in front of the first abdominal segment (UNT Lab Manual‚ 2017). We can measure the heart rate of the crayfish by measuring the change

factors that can influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that can affect the rate of this diffusion. Our intent

Although there was a short uptrend during last week‚ which was driven by yields‚ the investors worry more about deflation and the euro’s resilience. What’s more‚ the ECB rates are highly expected to be cut after ECB’s policy meeting on Thursday. The market is expecting a 25bps reduction in the benchmark rate to 0.50% from the current 0.75%. During the last week‚ many weak economic

If the participants in international trade are aware about exchange rate risks‚ they may prefer to switch to domestic activities where profits are relatively less uncertain rather than continuing trading in foreign markets. Alternatively‚ international traders may attempt to use forward foreign exchange markets in order to hedge against any possible losses.

In the face of rising inflationary pressure in Hong Kong‚ some people have suggested that the Linked Exchange Rate system is the root cause of the situation and that the Hong Kong dollar should no longer be linked to the US dollar. The Financial Secretary already stated in his blog on 14 August that the Link continues to be the most appropriate exchange rate arrangement for Hong Kong. I will elaborate further on a few related issues. Many people who advocate un-pegging the Hong Kong dollar from

Demonstration of the Rates of Reaction Between Sulphuric Acid (25mL ±0.5mL) and Magnesium (0.02g ±0.01g) Changing Due to Different Surface Areas By Chania Baldwin Introduction: When sulphuric acid and magnesium are added together‚ magnesium sulphate and hydrogen gas is created. To create such a reaction the atoms must collide with a sufficient amount of energy. Every reaction requires a different amount of energy to create the reaction‚ which is called the activation energy; when there is not enough

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over
