The purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

metabolic rate are investigated. Hypothesis: With the information given‚ we tested the effects of given hormones on the body by using virtual rats. We expect to see a greater metabolic rate for the normal rat as opposed to the thyroidectomized rat. The hypox rat is expected to have the lowest metabolic rate. Metabolic rate will increase once thyroxine is injected. TSH will increase the metabolic rate of all the rats with

(a) Give generalized conclusions (in point form) according to your observation in (a). 1. systolic pressure increases when the degree of exercise increases Systolic pressure increases gradually from 115 mmHg at rest to 150 mmHg during severe exercise. When thr degree of exercise increases‚ the skeleton muscle needs more energy(ATP) for rapid contraction by carrying out aerobic respiration. The skeleton muscle required faster uptake of oxygen and removal of carbon dioxide. At the same time‚ skeleton

factors that can influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that can affect the rate of this diffusion. Our intent

I have chosen this skill as I was nervous about performing it in practice and could reflect on my experience. The aim of this essay is to reflect and discuss learning achieved and my application of the clinical skill in practice. The NMC require that as a nurse “you must have the knowledge and skills for safe and effective

Introduction: High blood pressure or hypertension meaning high pressure (tension) in the arteries. Arteries are vessels that carry blood from the pumping heart to all the tissues and organs of the body. Normal Blood Pressure is below 120/80; blood pressure between 120/80 and 139/89 is consider pre-hypertension‚ and a blood pressure of 140/90 or above is considered high. The systolic blood pressure is the pressure in the arteries as the heart contracts and pumps blood forward into the arteries

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

Lifestyle Steps to Lower Your Blood Pressure How can I lower or prevent high blood pressure? Follow the guidelines below to help lower or prevent high blood pressure‚ also called hypertension. Maintain a healthy body weight If you are overweight‚ losing as few as 10 pounds may lead to a meaningful drop in high blood pressure. Medicine for high blood pressure may also work better after weight loss. If you have high blood pressure‚ it is very important to discuss these lifestyle and diet changes

The high blood pressure double whammy The double whammy for people with hypertension is that the extra adrenalin required by being overweight or obese: constricts our arteries and blood vessels to raise our blood pressure and give us an energy boost ready to defend ourselves or to escape a dangerous situation; and it could also lead to type 2 diabetes! The good news is that losing weight need not be difficult or involve unappetizing diets. Losing weight is a natural way to reduce our high blood
