A solution contained a mixture of three different amino acids. A scientist passed an electric current through the solution to separate the amino acids. She placed a drop of the mixture at one end of a piece of filter paper, attached an electrode to each end of the paper and switched on the current. She switched off the current after 20 minutes and stained the paper to show spots of the amino acids at new positions. Her results are shown in Figure 6. Figure 6 Drop of mixture placed here Filter paper Positive (+) electrode Negative (-) electrode Key • Spot showing the location of amino acids after 20 minutes 08 3 Explain what the positions of the spots in Figure 6 show about these amino acids. [3 marks] can someone please please answer this before tomorrow thank u :)
so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants
it can be observed without changing the identity of the object.
it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
