Use the organism that you used when completing this lab (commonly germinating peas).(A) Key points to include: the organism you chose, clear identification of the experimental variable, clear explanation for the variables that you must control, an explanation of the apparatus that you will use to measure the cellular respirationconsumed by germinating peas will be measured.Tags: Record Store Business PlanKinesiology Research PapersCritical Thinking Writing PromptsLow Cost Resume Writing ServiceDare Essay FormatEssay On New Year CelebrationTitle Page For Business PlanAnswers For Social Studies HomeworkEssays On How To Save WaterCreative Writing Assignment Ideas
Practice is crucial to divide your time efficiently.
You will get a ten minute reading period between the multiple choice and free response sections.
The graph shows that peas that have been germinating for three days consume more oxygen during a 30-minute period than peas that have been germinating for one day.
The peas that have only been germinating for one day are not as well developed.
I will be able to measure the amount of water drawn into the pipette by comparing where the water mark begins and where it ends. KOH will be added to an absorbent cotton ball and placed on the bottom of the respirometer with a non-absorbent cotton ball in between, so the KOH will not interfere with the experiment.
Because volume must be controlled, I will use glass beads to control the volume differences between the two germinating pea samples.This has created a very simple system for duplication.When a cell replicates its DNA during mitosis, it simply unzips the double helix and adds nucleic acids along its length until a duplicate set of complementary strands is created.The DNA strands are actually copied in small segments and linked together to form an entire strand.Although there are only four different base pairs, the longer the strand gets, the more combinations of base pairs can be created.Hypothesis: Measuring cellular respiration for 30 minutes at intervals of 10 minutes at a time will demonstrate that peas that have been germinating for three days will consume more oxygen through cellular respiration than peas that have been germinating one day.Procedure: I will place 20 peas that have been germinating for one day in one respirometer and 20 peas that have been germinating for three days in another respirometer.The high number of potential combinations from only four base pairs and the impact of small changes in the sequence of base pairs contributes to the diversity of proteins in an organism.This diversity of proteins contributes to the diversity of organisms that exist because physiological function is essentially protein driven.Therefore, these peas are not undergoing as much cellular respiration as the more developed peas that have been germinating for three days.All living organisms contain genetic information that provides several functions inherent to the individual organism and the perpetuation of its species.
