mixing of solute particles with water‚ Osmosis is water mixing with solute particles to pass through the cell wall and provide nutrients to the cell. Since osmosis is a type of diffusion that only involves water moving through the permeable membrane‚ salinity affects seed germination through osmotic effects (Bliss et al.‚ 1986). When NaCl is present‚ the concentration of water particles lower‚ making the seed incapable of reaching its necessary nutrients. Barley seeds are considered whole grains

with carbonate ions ( CO3-2) and Bicarbonate (HCO3) ions are formed. Thus ocean acidification decreases carbonate ions; This causes a problem for marine ecosystems‚ because carbonate ions are essential factor to marine life. The acidity of seawater is determined by the amount of hydrogen ions in solution ‚ which is then measured on the pH scale. The higher the concentration of hydrogen ions in a solution‚ the lower the pH of the solution. As stated in the previous paragraph‚ carbonic acid

Introduction An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚[4] they can be of any size but usually

a burning sensation tingling through me. Glancing up through the blue waves‚ I can make out the hot sun‚ its rays beating down onto the seawater. I feel strange and very hot‚ and I wonder what is in store for me next. Water around me also becomes warm and before I know it something very strange happens… I’m going up! Yes‚ up into the air and out of the seawater. Slowly‚ I’m traveling upwards‚ towards the vast‚ cloudy sky above me. I glance around‚ hoping to spot some other raindrops in a similar

be able to drink the water that we need. Desalination is a great way to provide more water for people. Taking salt out of seawater will provide for lots of people. In Carlsbad‚California they are building a desalination project. This will provide a natural water source for people to drink. When it is completed the huge plant will turn as many as 56 million gallons of seawater each day into drinking

Rocky Shore Ecology: Holbeck Beach This study was conducted to deduce whether the height to width ratio of limpets altered across the three main zones on the shore: upper‚ middle and lower. It was carried out on Holbeck Beach‚ North Yorkshire‚ where limpets were measured in all three zones using random sampling. We found a significant difference in the height to width ratio between the upper and lower shore and upper and middle shore. This is due to many factors‚ including the threat of desiccation

Alpine Spatial Patterns and Dimensions * Location: Kosciuszko National Park covers 6‚900 square kilometres and contains mainland Australia’s highest peak‚ Mount Kosciuszko. The park is located in the south-eastern corner of New South Wales‚ 354 km‚ southwest of Sydney‚ and is contiguous with the Alpine National Park in Victoria to the south‚ and the Namadgi National Park in the Australian Capital Territory to the north east * Altitude: Treelines can occur over a great range of altitudes

(can you please help me with my biology practical report‚ its about effect of salt in seed germination) I put seed in plastic container in the dark room…please help me with systematic and random errors) I need to hand up my assignment on 31st of October-2013‚ can you please help me AS SSON AS POSSIBLE THANK YOU‚ I WILL REALLY APPRECIATE YOU IN YOU HELP ME‚ YOU WILL BE GREATFULL FOR ME ) Abstract: The problem was to determine the effect of salt water on germinating radish and sunflower seeds

Washington are already seeing the effects of ocean acidity on their oyster products. They have been experiencing death rates up to eighty percent in their larvae‚ which is much higher than normal (Atkin). This is all due to using the highly acidic seawater to grow them. This market is worth up to $280 million each year‚ which could be lost because of the drop in pH levels of

Agricultural problems in Pakistan and their solutions IMPORTANCE: Economy of every state depends upon 3 sectors i.e. agriculture‚ industry and commerce. These three are interconnected with each other as the progress or retrogress of one sector effects the other two. Pakistan is an agricultural state thus agriculture gains are of much importance than any other sector. Importance of this sector is manifold as it feeds people‚ provides raw material for industry and is a base for foreign trade
