Christopher Bisda BIO 101 Week 1 Individual Assignment 02/08/2010 The Process of Science a. Chapter 2: Question 11 How might you use a radioactive isotope to find out whether the oxygen in CO2 comes from sugar or oxygen gas? I would substitute with a radioactive isotope of oxygen and run the reaction. Upon observation of the result‚ the oxygen came from what was used if the carbon dioxide is radioactive. If the carbon dioxide is not radioactive‚ then it came from the sugar. b. Chapter

Aim To work out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because

Did you know that one fully-developed tree produces oxygen for ten people every spring? Imagine walking on the sidewalk in your city’s downtown area. As you’re window shopping‚ you notice a tall‚ thin rectangular post implanted into the concrete substituting a tree. On the side of the post‚ there’s a slogan that reads nothing can replace a tree written in capital white letters with a black background. You pay closer attention to the sidewalk and realize that a silhouette of a palm tree is reflecting

Beanium Investigation The purpose of this investigation was to find the average atomic mass for the element Beanium with three isotopes. The average atomic mass is the average mass of the atoms of the element divided by the total number of atoms. An isotope is an atom with the same number of protons‚ but different number of neutrons; they are different forms of a single element. Since we knew the isotopes had almost the same amount of sub-atomic particles‚ we made our hypothesis the following:
