how increasing the temperature directed to yeast, affects its speed of producing carbon dioxide during yeast fermentation. I have the variables and method all planned out but the thing is, i don't know how i'm going to relate this to biology terms and concepts. I do know that yeast is a simple eukaryotic cell and may functions like one. Besides that, I also know that the cell membrane of yeast may break when uv light is directed on it, but i can't really seem to find and relate other biology concepts. Teacher asked me whats my objective of doing this and how i'm going to discuss it, suddenly I just really don't know what to answer. I hope you can help me. Thank you so so much in advance.

ning wave speeds through different mediums and had come across a confusing question. Can you state the speed of light from fastest to slowest as it passes (or doesn't) through the following: Liquid, solid, gas, and a vacuum?

it is Reading Break I am doubtful that I can contact my teacher before I need to know how to solve this. The following is the question: A light shines from the top of a pole that is 20 meters high. A ball is falling 10 meters away from the pole, casting a shadow on a building that is 30 meters away. When the ball is 25 meters from the ground it is falling at a speed of 6 meters per second. How fast is the shadow moving? Side note: from left to right are the following, lamp, ball, wall with shadow.

working on it since Friday) As it is reading break I doubt that I can cnotact my teacher before it is due. The question is as following: A light shines from the top of a pole that is 20 meters high. A ball is falling 10 meters away from the pole, casting a shadow on a building that is 30 meters away. When the ball is 25 meters from the ground it is falling at a speed of 6 meters per second. How fast is the shadow moving? side note: from left to right it goes lamp, falling ball, wall with shadow.
