The goal of the Global Polio Eradication Initiative is to ensure that no child will ever again know the crippling effects of polio. Polio is a highly infectious disease caused by a virus poliovirus. It invades the nervous system and can cause total paralysis in a matter of hours. It can strike at any age‚ but affects mainly children under three. Polio is mainly passed through person-to-person (i.e.‚ fecal-oral) contact‚ and infects persons who do not have immunity against the disease. There is no

Different methods of transpiration… Water uptake from the soil: Plant roots are surrounded by soil particles. The outmost layer of cells (the epidermis) contains root hair cells that increase the surface area of the root These cells absorb minerals from the soil by active transport using ATP for energy The minerals reduced the water potential of the cell cytoplasm; this makes the water potential in the cell lower than that in the soil. Movement across a root: The movement of water across the

Transport Systems Essay In single celled organisms‚ nutrients‚ water and various substances that are need for basic cellular processes can easily be transported in and out through the cell membrane. This is an effective transport system for microscopic organisms‚ but multicellular organisms require a more complex transport system to sustain itself. Take humans for example; unlike a cell‚ only the outer layer of skin is in contact with the body’s outside environment. It’s not possible for substances

rise in table water‚ which evidently increases salinity as the salt is ‘lifted up’ along with the water (Mdba.gov.au‚ 2015). If left unmanaged salinity can have many implications. Salinity can impact on Agricultural production‚ water quality‚ transpiration‚ soil erosion‚ biodiversity‚ irrigation and ecological health of streams (Mdba.gov.au‚ 2015). There are a number of ways to manage salinity in the landscape these include salt interception which involves moving the Murray River groundwater and

1. Describe the hydrologic cycle‚ and describe the difference between evaporation and evapo-transpiration. The hydrologic cycle is the system by which water continuously circulates through the biosphere (p.394-5). Evaporation is the process by which water changes from a liquid to a gas. Transpiration is the transfer of water from plants leaves and stems into the atmosphere. Evapo-transpiration is a combination of the two. 2. Discuss how human activity affects water quality according to our

STUDY GUIDE INTEGRATED SCIENCE 10 PLANT UNIT DO YOU/CAN YOU…. 1. Understand that both plants and animals (eukaryotes) undergo a similar process for cellular division/reproduction? Both plant and animal cells undergo mitosis and meiosis. In plants‚ there is an alternation of generations; the gametophyte generation‚ where haploid gametes (pollen and ovule; sperm and egg) are produced via mitosis. Then the sporophyte generation combines these two into spores via meiosis‚ resulting in a diploid

Abscisic Acid and Stomatal Closure Abscisic acid is a single compound unlike the auxins‚ gibberellins‚ and cytokinins. It was called "abscisin II" originally because it was thought to play a major role in abscission of fruits. Though ABA generally is thought to play mostly inhibitory roles‚ it has many promoting functions as well. In 1963‚ abscisic acid was first identified and characterized by Frederick Addicott and his associates. They were studying compounds responsible for the abscission
