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

Bio 104-03 Lab #3- Acids Bases‚ and Buffers 1. An acid is a substance that releases hydrogen ions as they desolve in water and ranks lower than seven on the pH scale. An example of an acidic substance is lemon juice. A base is a substance that accepts hydrogen ions and ranks higher than seven on the pH scale. An example of a base substance is hand soap. A neutral substance ranks a seven on the pH scale and has equal concentrations of H+ and OH-. An example of this is pure water. Electrolytes

Unit 1 Assignment 1: Homeostatic Balances Homeostasis is maintaining an Internal Balance. If we fail to maintain an internal balance every system inside of our body will be disrupted. Hypertension To explain to a 65 year old man with an 8th grade education‚ that he has hypertension‚ I would begin explaining‚ in a manor I believe that he would understand‚ what hypertension is and how it can affect him. ‘Hypertension is when your blood pressure is high on a daily basis. Blood pressure is considered

“Brain Lab” Questions: 1. Structure Function Frontal Lobe It contains centres for reasoning and movement. Parietal Lobe It is for somatic sensing and taste. Occipital Lobe It is responsible for processing visual information from the eyes. Temporal Lobe It is involved in primary auditory perception‚ such as hearing. Cerebrum (Cerebral Hemisphere) It is the largest part of the brain which is the last centre to receive sensory input and integrate them. It also coordinates the activities of the other

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

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

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the
