You have already collected data on your Redbud seed samples and recorded that information individually and also as a class section. The hard copy Table that you used to record that information will be returned to you for your use in this final. The first thing you need to do is to convert your class totals to percent so they can be compared to one another. To do this take each of the 4 category count (Good Seeds, Aborted Seeds, Bruchid, Chalcid) and divide each by the total number of seeds analyzed by your class. Round off your number to a whole number (ie 3.87 rounds off to 4).

For example: Good Seeds 50/Total Number of Seeds 200 = .25 or 25%

Do this in order and place your answers in the following question boxes for each of the categories. Your entry should be a number (25) versus the decimal (.25) equivalent. Do not enter the % percent sign.

Good Seeds = ___________%
5

Bruchid Infested Seeds = ___________%
7
1
Chalcid Infested Seeds = ___________%

Now, insert the percents you just calculated into the Table so you can compare your class results to the total results for all 5 sections of biology classes.
9
1
Describe how your individual class percents compared to the total percent for all 5 classes.
A Our class results were very similar, all were less than 2 percent differences + or - from the Total 5 Classes.
B Our class results were about the same, at least one number was between 3 to 5 percent differences + or - from the Total 5 Classes.
C Our class results were substantially different from the Total 5 Classes (at least one number was greater than 5% difference).

Based on your results and using them to support your view, explain whether you think the total infestation percentage poses a threat to reproductive potential of the Redbud tree. (Reproductive potential is the number of good seeds available that could grow into a new plant.)
A No. The combined infestation percentages were low (less than 10%) compared to the total viable (good) seeds.
B Yes. The combined infestation percentages were high (greater than 10%) compared to the total viable (good) seeds.
11
1
Select a possible hypothesis for the experiment.
A If Redbud seeds are infested, then reproductive potential will be low.
B The Redbud reproductive potential will be high if there is no infestation by insects.
C If the Redbud seed reproductive potential is high, then there will be a large insect infestation and aborted seeds.
D Infestation by insects causes a low Redbud seed reproductive potential.
12

Identify a constant in the experiment.
A the Redbud tree species
B the students who did the experiment
C the redbud seeds
D the amount of light in the room where each student examined the seeds
13

Quantitative data was collected because students had to judge whether the seeds were good, aborted or infested, however, qualitative data was finally collected when students counted and tabulated the number of seeds in each of the categories.
True
False
14
1
Explain the benefit of increasing the sample size. (Why did we use the class totals compared to one set of individual data?)
A The larger the sample size the greater potential for accuracy.
B The larger the sample size the more likely it will be that the hypothesis is correct.
C The larger the sample size the less likely it will be that the hypothesis is incorrect.
D The larger sample size doesn't effect the outcome of an experiment.
15
1
State whether you think this study ( underestimated or overestimated ) the reproductive potential of the Redbud tree and why.
A underestimated because a better process was needed to determine viability of the seeds (aborted seeds were determined only by sight).
B underestimated because the samples were taken from only one tree in Lawrence.
C overestimated because a better process was needed to determine viability of the seeds (good seeds were determined by sight only)
D overestimated because not enough samples were surveyed (opened and had the seeds examined)

Insert the organisms in this study into the bubbles in this Conceptual Model of Carbon Flow Through the Redbud-Bruchid Beetle-Chalcid Wasp Ecosystem. The 5 terms you will insert are: Atmosphere (A), Bruchid beetles (B), Chalcid wasps (C), Decomposers (D), and Redbud tree (R). To make this easier abbreviate the terms by using the letter provided after each term.
In 2014 biology class students collected the same type of data that you did in your experiment (2017). Study the graphs below comparing the two sets of data.
23
1
The data collected in 2014 and 2017
A shows that there was a large difference in the number of good and aborted seeds.
B shows that the redbud reproductive potential was the same.
C shows that the infestations in 2014 were almost double of those in 2017.
D shows that the students in 2014 didn't do as good of a job as you did in 2017.

Since seeds need water to grow and plants continue to need water to stay healthy, grow and reproduce by making flowers with seeds in them, consider the table showing yearly actual rainfall compared to the average expected rainfall per year for 2013, 2014, 2015 and 2016.

The rainfall amounts for 2013 and 2014 would have influenced the health and growth ability of the redbud tree and the seed collected in 2014.

The 2016 rainfall amount would influence the health and growth ability of the redbud tree in the seeds collected in 2017. (Be sure to consider the rainfall amounts in 2015.)

Select a hypothesis that might be drawn based on this observation.
A If yearly rainfall is equal to or above the average rainfall, then redbud reproductive potential increases.
B If yearly rainfall is less than the average rainfall, then redbud reproductive potential increases.
C When the amounts of rainfall are equal to or greater than the average, the redbud reproductive potential will decrease.
D When the amounts of rainfall are less than the average rainfall, the redbud reproductive potential will increase.

The percentage of aborted seeds in 2014 is very high, 67%. One of the causes of aborted seeds is a lack of fertilization from pollination.

A recent concern about the sudden death of honeybee populations has been in the news. Scientists and bee keepers haven't been able to determine the reason behind the deaths. Speculation is that continued use of pesticides has caused increased reservoirs of the chemicals in the bee's ecosystem and the higher concentrations are now causing them to die. Should there be a concern about the loss of pollinators?
A Yes. Without pollinators we would lose our plant based food sources.
B No. There are lots of other pollinators besides honeybees, so we don't have to worry about losing our plant based food source.
For now, you are done analyzing and commenting on the data you collected in your class experiment.

C All energy is dissipated (lost) into the environment as heat.
D Some energy is stored within the organism; the rest reverts back to the producer.
27
1
Why do all living things depend on the cycling of matter?
A Living things are part of the cycles.
B Living things need the energy that comes from cycling of matter.
C Living things create new matter, which is then added to the cycle.
D Matter cannot be created, so resources must be recycled to support continued life processes.

You want to know if you give a plant more water if it will grow taller.

The experiment you design is to use five (5) pepper plants that are already 10 centimeters tall and to give each of them a different amount of water every three (3) day for a month.

One plant will receive no water. One plant will receive 25 ml, one 50 ml, one 75 ml and one 100 ml of water. You will measure the plants after a month and record your data. All plants are placed in the same type of containers, soil and location.
A The plant species; same soil, container and location; and same watering schedule are all examples of constants in this experiment.
B A possible hypothesis for this experiment is: If plants will grow taller with more water, then the plant receiving the most water will be the tallest at the end of the experiment.
C The plant that received no water in this experiment is a control.
D All of the statements are true.
29

The results for an experiment to see what the addition of different quantities of water will do to the growth of a plant are shown in the Table above. One possible hypothesis for this experiment is: If plants grow taller with more water, then the plant receiving the most water will be the tallest at the end of the experiment. Based on the results in the Table above, what is correct about the hypothesis.
A You have to accept the hypothesis that it is true because the plants receiving 75 ml of water were the tallest.
B You have to reject the hypothesis because the plant with the most water wasn't the tallest at the end of the experiment.
C Your data is inconclusive, so you can't reject or accept the hypothesis.
D The data was inconclusive, so you need to rewrite the hypothesis and redo the experiment.
30
1
Explain why the experiment above had a group of plants that received no water.
A This was a control so you could tell the difference between plants that were watered and not watered.
B Since the original height of the plant was 10 cm, this showed that there was no grow without water.
C This was a constant so you could tell the difference between plants that were watered and not watered.
D This was the independent variable which was being manipulated in the experiment.
31
1
Why is it important to have only one independent variable in an experiment?
A Because it is too difficult to set-up an experiment with more than one independent variable.
B Because it costs too much to set-up an experiment with more than one independent variable.
