Iker Lopez Anatomy & Physiology P2 Wednesday‚ September 19‚ 2012 Heart Rate Response to Baroreceptor Feedback Lab Fundamental Question: Does the body respond to its environment? Testable Question: When the body is in the squat position to normal while the time limit stays the same and how far you squat is the same‚ will the heart rate recover after returning to standing position in 10 seconds? Hypothesis: If the body moves back to normal position from squatting position while the time limit

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

understand the photosynthetic process to help enhance the efficiency and quality of life on Earth. By fully understanding the function of photosynthesis‚ some environmental adjustments can then be made to refine the photosynthetic process. In this lab specifically (Lab No. 7)‚ we isolated specific color wavelengths and recorded the rate of photosynthesis in comparison to the unaltered rate of photosynthesis

neither man would expect the effect these elements could have on modern science‚ namely rockets. But creating a rocket is just combining these two gases in a closed environment‚ and one spark. This lab exemplifies just that what happens when the gases H2 and O2 are chemically combined with a spark. In this lab‚ the objective was to see how far a pipette filled H2 and O2 could travel. One half a centimeter of H2O was added to keep the gases inside‚ and make sure that only these H2 and O2 where included

Introduction to Microscale Laboratory Niki Gharavi *‚ Minh Nguyen San Jose City College ABSTRACT: The objective of the experiment was to be introduced to working with the lab equipment‚ specifically heating and measuring‚ and to be able to create some of the apparatus that future experiments will require. Heating methods used were an aluminum block‚ a sand bath‚ and a water bath. The aluminum block heated most quickly while the others were more stable. Regarding the measurement of water‚ the less

One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

Pseudomonas aeruginosa Pseudomonas aeruginosa is the bacteria of my initial unknown project. Determining which bacteria I had was completed by many steps. The one fact that I had‚ was that it was a gram negative bacteria because on the gram stain it appeared pink. Its cell wall is composed of a plasma membrane‚ periplasmic space‚ peptidoglycan and an outer membrane (lipopolysaccharide and protein). By looking at the agar plate it was easy to tell that it was not a swarmer and it did not have any

The experimental membrane we used in this lab acted as a barrier in which only a small number of molecules can pass through. In this experiment we wanted to show the process of osmosis‚ in which water passes through the aforementioned barrier. Osmosis is critical to life because the process regulates

of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion is present in the K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O using
