INTRODUCTION Osmosis is a passive movement of water molecules going across the partially permeable membrane. It is a very spontaneous process due to the downhill energy flow known as “water potential” by which‚ water molecules move

High Blood Pressure Living a healthy lifestyle is the dream of every person but many of us facing the problem of high blood pressure known as silent killer. The research shows that high blood pressure is rapidly increasing and every third person is stuck with disease. High blood pressure refers to pressure of blood against your artery walls that leads to the heart disease and you need to arrest this silent killer before it strikes you as the research shows that above then 50 percent patients with

Research Caffeine is a bitter white crystalline alkaloid. Its chemical formula is CaH10N4O2. Caffeine also affects the human body. It is widely consumed by people of all ages. In the last period a market of caffeine-containing products‚ particularly energy drinks and food supplements increased. Caffeine for years is under discussion‚ whether it has positive adverse impact on health. Children are a group of special anxieties. Caffeine is a stimulant of central nervous system and

This lab focused on three factors affecting reaction rates‚ temperature‚ surface area‚ and concentration. Our first experiment (table 1) looked mainly into the effects of temperature on the reaction rate. To see how different temperatures would change the reaction rates we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams

Measurement of Heart Rate for Autonomic Nervous System Abstract: The Autonomic Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger

1. For each of the following (a through d)‚ indicate which is a variable and which is a constant: a. The number of minutes in an hour. Constant b. Patients’ systolic blood pressure Variable c. Pi (π) – e.g.‚ for finding the circumference of a circle Constant d. College students’ level of depression Variable 2. For each of the following research questions‚ identify the independent variable and the dependent variable within each case (a through e): Does a person’s age affect psychological

In this lab the rate of germination in relation to temperature was observed testing the hypothesis‚ if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray

DEMENTIA AWARNESS 1.Understand what dementia is 1.1 Explain what is meant by the term ’dementia’ A syndrome due to disease of the brain‚ usually of a chronic progressive nature in which there are multiple disturbances of higher cognitive function. These include impairment of memory‚ thinking and orientation‚ learning ability‚ language and judgement. 1.2 Describe the key functions of the brain that are affected by dementia The key functions of the brain that are affected by dementia are the temporal

the main focus is to oxygenate the blood. The body does this through one of the bodies organs‚ the lungs. Low oxygenated blood is pumped through the pulmonary arteries to the lungs. Whenever we breathe this low oxygen blood is turned back into oxygenated blood when carbon dioxide is forced into the air and oxygen reenters the body. The reoxygenated blood then reenters the heart. For this lab‚ the expected outcomes are that when the heart rate and blood pressure are measured‚ both will increase when

Chirped Pulse Fourier Transform Microwave (CP-FTMW) Spectrometer Abstract: Under the condition in which electric and magnetic fields are absent‚ rotational constants is a three molecular constants that substantiate polyatomic molecule. In this laboratory experiment at Missouri University of Science and Technology‚ we are going to collect rotational spectra by using 2 separate types of microwave spectrometers -- the FTMW (Fourier Transform Microwave) spectrometer and CP-FTMW (Chirped Pulse Fourier
