Unformatted text preview: Fill in the table and Graph Net and Gross Productivity vs % of light Using your data table, what seems to be the trend as the % of light decreases? WHY? Using your data table, what seems to be the trend as the % of light increases? WHY? Where would you say this organism is using as much energy as they are making? WHY? Using your table and graph, explain why most of the time there are bigger plants on land than in the sea? Explain this in terms of evolution % light DO (mg O 2 /L) Gross PP = Bottle – Dark (mg O 2 /L) Net PP = Bottle – Light (mg O 2 /L) Gross Carbon fixed in mgC/L Gross PP x 0.698 x 0.536 Initial 8.4    Dark 6.2    100% 10.2 65% 9.7 25% 9.0 10% 8.5 2% 7.1 Dilution & pH Review C 1 V 1 = C 2 V 2 C 1 = original concentration of the solution, before it gets watered down or diluted. C 2 = final concentration of the solution, after dilution. V 1 = volume about to be diluted V 2 = final volume after dilution By drawing the " X " through the equal sign and filling in the formula with letters of a size permitted by the borders of the " X ", it reminds you that : for all dilution problems C 1 > C 2, and V 1 < V 2 . It makes sense because to dilute, we add water. This increases the volume but lowers concentration. Examples by Type : 1. Easiest: Joe has a 2 g/L solution. He dilutes it and creates 3 L of a 1 g/L solution. How much of the original solution did he dilute? 2. Joe has 20 L of a 2 g/L solution. He diluted it, and created 3 L of a 1 g/L solution. How did he make such a solution? 3. Joe has 20 L of a 2 g/L solution. To this solution he adds 30 L. What is the final concentration of the solution? pH Reminder: pH = log (H + ) Which is more acidic? (H + ) of 1.0 x 108 or 1.0 x 1012 Which is more basic? (H + ) of 1.0 x 106 or 1.0 x 103 Stomach acid has a pH of about 12. What would the H + concentration be around? [H 3 O + ] or [H + ] scientific notation pH 0.1 0.01 0.001 0.0001 0.00001 0.000001 0.0000001 0.00000001 0.0000000001 0.00000000001 As [H + ] gets smaller, scientific notation exponents get ________________, and pH goes __________ As [H + ] gets larger, scientific notation exponents get ________________, and pH goes __________ Random Questions 1. Hydrogen peroxide is broken down to water and oxygen by the enzyme catalase. The following data were taken over 5 minutes. What is the rate of enzymatic reaction in mL/min from 2 to 4 minutes? 2. Data taken to determine the effect of temperature on the rate of respiration in a goldfish is given in the table below. Calculate Q 10 for this data. 3. If 250 people out of a population of 1,000 are born with sicklecell anemia, how many people in the population will be more resistant to malaria because they are heterozygous for the sicklecell gene? 4. In a population of 250 peas, 16% of the peas are homozygous recessive wrinkled and the rest are smooth. What is the frequency of the dominant allele for smooth peas? 5. There are 2,000 mice living in a field. If 1,000 mice are born each month and 200 mice die each month, what is the per capita growth rate of mice over a month?...
