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

"When a person glimpses the face of a famous actor‚ sniffs a favourite food or hears the voice of a friend‚ recognition is instant. Within a fraction of a second after the eyes‚ nose‚ ears‚ tongue or skin is stimulated‚ one knows the object is familiar and whether it is desirable or dangerous. How does such recognition‚ which psychologists call preattentive perception‚ happen so accurately and quickly‚ even when the stimuli are complex and the context in which they arise varies? Much is known about

The Affctive Filter Hypothesis :- The fifth hypothesis‚ the Affective Filter hypothesis‚ embodies Krashen’s view that a number of ’affective variables’ play a facilitative role in second language acquisition. These variables include motivation‚ self-confidence and a low level of anxiety are better equipped for success. Low motivation‚ low self-esteem‚ and debilitating anxiety can combine to ’raise’ the affective filter and form a ’mental block’. Comprehensible input may not be utilized by second-language

White King‚ Red Rubber‚ Black Death “White King‚ Red Rubber‚ Black Death‚” illustrated how King Leopold II of Belgium acquired the Congo as a free state and exploited it by reign of terror. King Leopold II took over leadership of Belgium from his father‚ hoping to gain power and wealth‚ as well as assuming control of overseas territories like most other European nations of the time did. Leopold created‚ through political lobbying and military force‚ the Belgian Free State. The Belgian Free State

Little lights shine their way down the rugged winding path. Foot steps trudge in front and behind staying close together. Dodging thorns and burs left and right. Ouch!—Every time. Quiet laughs fill the silence as we continue on. Our trek ascends us up a treacherous slope and through a cow pasture carpeted with mines and under a barbed wire fence and down a mile long tractor path that feels like an eternity all with our bags and rifles being persuaded down by gravity. Finally‚ we make it to where

low-pass filter is an electronic filter that passes low-frequency signals and attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. It implemented using a resistor and a capacitor. The actual amount of attenuation for each frequency varies from filter to filter. A low-pass filter is the opposite of a high-pass filter. The below circuit diagram illustrates a simple ’RC’ low-pass filter. The range of frequencies passed by a low pass filter within a
