EFFECT OF INTEREST RATE ON FOREIGHN EXCHANGE RATE (EVIDENCE FROM ASIAN REGION) ABSTRACT: In this article we investigate the impact of a change in U.S. short term interest rates relative to those in some Asian countries like Bangladesh‚ Thailand‚ Japan‚ Pakistan‚ and China on the bilateral foreign exchange rates between the U.S dollar and each country’s currency. Several factors determine the exchange rate of a country. A higher currency makes a country’s exports more expensive and imports cheaper

Abstract: The rate of photosynthesis and cellular respiration can change in varying conditions. How does the rate change with varying degrees of temperature and light exposure? To test this algae beads were exposed to a CO2 indicator‚ which changes colors based on the level CO2 level present. The algae beads were exposed to two different variables‚ light and temperature and tested for color change‚ Ph‚ level‚ and CO2 absorbance level. The beads were exposed to a light and a dark condition‚ and another

process of photosynthesis requires sunlight for its nutrients to make their way into the chlorophyll on green plants. This suggests that without direct sunlight‚ photosynthesis will not be completed correctly or the plants functions will not work properly. Majority of plants that undergo photosynthesis have chlorophyll stored within them‚ it is what gives them their green color. However‚ there are few species of plants that don’t acquire chlorophyll‚ but still undergo the process of photosynthesis. Specific

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

filters and the percent orange light transmittance through the solution was measured to determine the rate of photosynthesis. This experiment was set up to discover how different wavelengths of light affect the rate of photosynthesis in a spinach‚ DPIP‚ phosphate solution. I proposed that the spinach‚ DPIP‚ phosphate solution under no filter‚ and therefore exposed to all light will have a highest percent orange light transmittance and a highest rate of photosynthesis. The solution under the red filter

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye‚ and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm)‚ or 400×10−9 m‚ to 700 nanometres – between the infrared‚ with longer wavelengths and the ultraviolet‚ with shorter wavelengths. These numbers do not represent the absolute limits of human vision‚ but the approximate range within which most people can

adding hydrogen to them. In prokaryotes instead of chloroplast they use their own cell membranes to do the job. Wavelength also has a role in photosynthesis because they have just the right amount of energy to excite chlorophyll electrons boosting them to a higher energy level. When summing everything up the reactants are carbon dioxide‚ water‚ and the suns energy and the process is light dependent and the Calvin cycle. The products include oxygen and glucose. Pigments serve as photosynthetic organisms

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be
