Hydrophytes Hydrophytes are plants that live in aquatic habitat. Hydrophytes can be divided into two types; fully submerged in water or partially submerged in water. These plants can absorb much water as they live in water habitat. Hydrophytes have various features in order to adapt in the aquatic environment in terms of morphological and anatomical adaptations. The morphological adaptations are divided into roots‚ leaves and stems. The roots of hydrophytes may be absent or poorly developed as

It is no secret that exercise is important to an individual ’s physical and mental health. Physical exercise has been attributed to improved circulation and blood flow to the brain which results in improved overall health. The effect of aerobic exercise on one’s mental health is not as well understood. The increased cognitive benefits of aerobic exercise can be used to promote healthy lifestyles in all individuals young and old. We seek to find a correlation between physical activity‚ specifically

The Effect of Light Intensity on Photosynthesis and Transpiration Inna V. Raymundo BOTANY I Section V-6L August 29‚ 2012 ¹A scientific paper submitted in partial fulfillment of the requirements in Botany I laboratory under Dr. Nonnie Bautista‚ 1st sem‚ 2012-2013. ABSTRACT Photosynthesis and transpiration both play important roles in plants. But there are factors which affect the rate of photosynthesis and transpiration. The external factor that was identified is the

ROOTS * is an organ of a plant that typically lies below the surface of the soil. * a part of a plant body that bears no leaves‚ and therefore also lacks of nodes. * is the beginning of the vascular system pipeline that moves water and minerals from the soil up to the leaves and fruits. FUNCTIONS OF ROOTS: * Underground (usually) * Anchor the plant in the soil * Absorb water and nutrients * Conduct water and nutrients * Food Storage ROOT SYSTEM: 1. Tap root system

Steven Gard Case Study 3 7/18/2012 s2444532 R.S. has smoked for many years and has developed chronic bronchitis‚ a chronic obstructive pulmonary disease (COPD). He also has a history of coronary artery disease and peripheral arterial vascular disease. His arterial blood gas (ABG) values are pH = 7.32‚ PaCO2 = 60 mm Hg‚ PaO2 = 50 mm Hg‚ HCO3- = 30 mEq/L. His hematocrit is 52% with normal red cell indices. He is using an inhaled ß2 agonist and theophylline to manage his respiratory disease

REPSIRATORY DEPTH Depth- amplitude of each respiratory movement The depth of ventilation refers to the amount of air that is inhaled and exhaled. The amount of air inhaled and exhaled in one cycle is called the tidal volume. The more the chest cavity expands‚ the greater the depth of the ventilation. Full expansion of the chest wall with full relaxation on exhalation is a good indicator of adequate depth of breathing and adequate tidal volume. Many books will try and apply numbers in milliliters

Plethysmography is used to measure changes in volume in different parts of the body. This can help check blood. The test may be done to check for blood clots in the arms and legs‚ or to measure how much air you can hold in your lungs. Lung plethysmography: You will breathe or pant against a mouthpiece. Clips will be put on your nose to shut off your nostrils. Depending on the information your doctor is looking for‚ the mouthpiece may be open at first‚ and then closed. You will be breathing
