PH

3.3.2 pH Analysis The pH will be determined using an electrode with a penetration probe coupled to a calibrated portable pH meter. The samples will be analyzed in triplicate per treatment, and the mean value will be obtained from the fish sample. 3.3.3 Acidity analysis For the determination of acidity, 10g samples of three fish sample from each treatment will randomly selected, crushed and homogenized with 200 mL of distilled water in an Ultra-Turrax homogenizer for 1 min. This solution will be

five senses, this is possible because its effects are happening undersea. The sources of most carbon dioxide emissions is through the burning of coal , and gas. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH value drops immensely. An example of the effect of ocean acidification on marine species is that of the shells of crustaceans, mussels and many others. These important animals shells are dissolving due to the

Pool Operations Pool Operator, Records and Plans The pool operator has appropriate training for maintaining and operating the pool. In addition, the operator was also the only caretaker of the pool and was knowledgeable and active with the pool safety plan and pool records. To illustrate this, the operator knew where the safety equipment were located in the pool area; how to balance and maintain the pool water; and performed the regular maintenance and cleaning of the pool. Also, the Fraser Health

can take up to 3-12 months for compost to fully decompose. The topic is decomposition rate. The IV would be the pH level in the compost. The DV would be the rate of decomposition. The constant is the compost without anything added. The controls are the environment, compost materials, scientists doing the experiment, way of measuring,

Over 350 million years ago, the shark species has been labeled as the apex predator of the sea. With the increase in human population the demand for shark meat and fins are at an all time high therefore, the existence of the shark is becoming a concern. Individuals are observing to think of sharks as a negative feature to the environment, which is prolonging the effect to prevent shark species from becoming extinct. With that in mind, not only are human over-fishing sharks, but also the CO2 emission

Brittany Roberts AP bio WATER ESSAY The first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. Water covers about 3/4 of the earth. In nature, water naturally exists in all three physical states of matter—solid, liquid and gas. Water's extraordinary properties are emergent properties resulting

The damage it causes to the skin may be irreversible. Safety glasses are very important as if this harmful chemical

WEEK 2 Written Assignment I’m thinking no more than 1-2 paragraphs each for 3 & 4. 1. List the qualities (at least 6) that define life AND discuss how a single-celled organism, such as an Amoeba or a yeast cell, and a more complex one, such as a tree or a cat, matches up with each characteristic 1. Living things have cells. 2. Living things grow 3. Living things reproduce 4. Living things respond to stimuli 5. Living things use energy 6. Living things adapt to their environment A single celled

The West African Black Rhinoceros, the Caribbean Monk Seal, the Tasmanian tiger, And the Javan Tiger all have one thing in common, they are now extinct. And the reason? The reason is all around you. In the 3.5 billion years Earth has sustained life, there have been five major extinctions in the past 500 million years caused by natural disasters. Today, there are about sixty-six known species that are either endangered or vulnerable to extinction. Due to human activity, we are now undergoing a worldwide devastation

3.0 MATERIALS AND METHODS 3.1 Materials 3.1.2 DOWEX TAN 1 DOWEX TAN 1 is a macro porous strong base anion exchange resin with quaternary amine functionally designed for the removal of large natural organic compounds (NOM) from drinking water to reduce color and THM precursors. The resin was obtained from DOW chemicals. The resins are opaque white beads with particle size ranging from 0.3 to 1.2 mm and total exchange capacity is greater than 0.7meq/ml. 3.1.2 IRA-67 Weak base anion exchanger IRA67
