9.2.6 Explain how water moves from the soil to the leaves of a plant. At first water enters the root by osmosis because the soil water has a lower solute concentration of minerals than the epidermal cell cytoplasm (there is a water potential gradient). Water movement across the cortex cell is by two pathways both involving a water potential gradient. The cortex cell cytoplasm has a solute concentration gradient. This moves water symplastically from cell to cell by osmosis. The Apoplastic

Differences in Cardiovascular Fitness that Effect Nonsmokers and Smokers Kayla Forbes 2-15-12 Bio Lab 140/77 Hilde Stawski Abstract: The goal of this experiment was to find out how smoking affected nonsmokers‚ light smokers‚ and heavy smokers heart rate during cardiovascular endurance. The participants will record their pulse rate before and after every minute for six minutes after the step test. As predicted‚ the heavy smokers had an increase in pulse rate that was twice as high as the

Laboratory report investigating the equine respiratory and cardiovascular systems Introduction The respiratory and cardiovascular systems of the horse work together to transport oxygen around the body and play an essential part in providing the horse with its increased need for oxygen during exercise. They allow the musculoskeletal system to use energy to facilitate motion. The cardiovascular system comprises the heart‚ blood vessels and blood. The heart pumps blood around the body

CARDIOVASCULAR SYSTEM OF THE HEAD NECK The cardiovascular system consists of the heart‚ blood vessels‚ and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen‚ nutrients‚ hormones‚ and cellular waste products throughout the body‚ the cardiovascular system is powered by the body’s hardest-working organ — the heart‚ which is only about the size of a closed fist. Even at rest‚ the average heart easily pumps over 5 liters of blood throughout

Cardiovascular Disease Ashley Cookie Cardiac Arrest Mr. Stapleton November 20th‚ 2012 Would you like to feel or be close to death? How would you like to have your heart pump rapidly out of control? A cardiac Arrest is the absence of ventricular contraction that results in systemic circulatory failure. A Cardiac Arrest is something that can happen out of nowhere without you knowing. You can be cooking and you just collapse and go into Cardiac Arrest. It’s that easy!
