In this lab report we will be conducting an experiment to test for cellular respiration in germination. When germination occurs cellular respiration provides plants with the ATP needed to produce all the molecules that they require to grow. So in the experiment that follows serves for the purpose of measuring the amount of oxygen uptake and use that as proof that germinating soy beans are in fact carrying on cellular respiration. My hypothesis of course being that soybeans do in fact carry cellular respiration out but not non-germinating soybean seeds.
For this experiment I will be utilizing a volumeter with three respirometers, which is used to measure change in gas volumes. I’ll start off by removing the three vials from the volumeter and labeling them as A, B and C.
We’ll then place absorbent cotton at the bottom of each vial and wet the cotton with 15% potassium hydroxide (KOH) without wetting the sides of the vials. The KOH will absorb CO2 produced by the soybean seeds. After this place dry cotton on top of the wet cotton. Next we are to count twenty-five soybeans and add them to vial A. In vial B we will place twenty five non-germinating soybean seeds and add glass beads until the amount of volume occupied is roughly the same as in vial A. We will add glass beans to vial C and bring it up to about the same volume as in vials A and B. Finally I’ll replace the vials into the volumeter and place two-hole stoppers in each. Each of the stoppers has a vent and this vent is clamped shut. I removed the clamps and adjusted the side arm so that about 5mm-1cm has gone through the stopper. Now using a Pasteur pipe to insert Brodie manometer fluid, which is simply water colored with vegetable dye and a small amount of detergent, into each side arm until there is
Pregame Prayer in Today’s Youth The smell of fresh cut green grass. Dirt from the infield spread evenly over the diamond shaped field from first base across to third base. The freshly cooked scent of goodies from the food stand, getting ready for the start of the game that is about to start. On the outfield grass in the distance, there are about six baseball players from the home team who know they are about to get part of their uniform dirty and they all start to kneel down to one knee. With the…
Writers and speakers have a large impact on the ideas and opics people consider to be inethical or unfair. People are able to convince others, whether through speech or writing about their ideas. During he mid 19th century and mid 20th century there were laws that caused problems for certian people, like women, blacks, and other minorities. Just like today people spoke out against those problems they were facing and pushed for others to see what their potential could be without these things limiting…
Imagination is a big part of lives As a young kid we all imagine or make believe things that are not real, are real. There isn’t anything wrong with making believe or pretending. Pretending or imagining things as a kid can be a great way for the mind to be stimulated it can show where a child’s head is at. We should continue to let our kids imagine, and pretend. What can we learn from using our imagination is learning who we are as people? What we like to do or how creative we can be. We can…
Tara Nemec Eric Schmitt English 1001 12 November 2009 Animals Used For Clothing Attending the zoo when you were a child was the best day ever at the time. You would walk in and see glass cages with different kinds of animals to your left and your right with all kinds of vegetation, each satisfying the needs of that animal. You would run up to the cage, face squished up against the glass and just stare at them for minutes in amazement even if they were just sleeping or sitting still. You…
Annotations for To Kill A Mocking Bird 1. Diction Chapter 1, Pg. 6 “Our mother died when I was two, so I never felt her absence… I did not miss her, but I think Jem did. He remembered her clearly, and sometimes in the middle of a game he would sigh at length, then go off and play by himself behind the car-house. When he was like that, I knew better than to bother him.” This quote shows that Jem and Scout are motherless but have their maid Calpurnia and that their father, Atticus was wifeless…

Perry and Maier both believed in the historical history of the bible but they had different points of views. In the readings from Perry there was a statements made on page 36 that seemed or sound as though he don't entirely believe or agree with all the bible in tell. I totally disagree when Perry stated that the bible contains factual errors, folklore and legends. Do to the fact that from the Book of Genesis stated that God created everything from the heavens and the earth to light, life and humans…
Warren Christopher believes that humans need to be able to depend on and trust one another, he shared with us three examples to illustrate his beliefs. He tells us how he once was driving down a two-lane highway at sixty miles an hour, and on the opposite side of the road, another car was approaching him around the same speed. He looked at the drivers eyes for just a second, and wondered if the driver depended on him, like he did on the driver. Even though no words were heard or spoken, they both…
Comedic Review for Jo Koy In Jo Koy’s new Comedy Central special, “Don’t Make Him Angry”, he builds his material on typical stereotype humor yet adds playful ties with familial additions from his own daily experiences. Jo Koy doesn’t shy away from his Filipino heritage. Contrastingly to many other comedic genres, Jo koy addresses more detrimental issues like raising kids. All of these comedic topics are executed in Jo Koy’s great method of character portrayal through voices and gestures. Unlike…
Participants in the action, some of them in parts that are minor and seem insignificant, contribute one by one the indispensable stitches which make the pattern, and contribute them not knowing; that is to say, they act when they do not know the truth of the situation in which they act, this truth being known, however, to us who are spectators." (The Brevity of Friar Laurence, 850) The idea that Fortune dictates the course of mankind dates back to ancient times. Those writers of the medieval world…
