Question: What is the effect of calcium in different concentrations on lima bean growth? Personal Engagement: For my internal assessment‚ I chose calcium because it interested me how adding a certain nutrient or element‚ can aid in growth of an organism. Calcium is a vital nutrient needed by most organisms and can be found in many things we consume like milk. Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima

“Electrolytes turn on all thought and motion‚ almost like a wall switch. They trigger all events like muscle action by controlling ion channels”(Edward Kane‚ 2010).Electrolytes have four minerals that include Sodium‚ (Na) Potassium‚ (K)‚ Magnesium (Mg)‚ and Calcium (Ca). Electrolytes help us by giving us an electrically-charge. Our brain uses it‚ so that they can send messages to others parts of our body so it can continue its function. And that’s very important because without it our nervous system‚ heart

In an abbreviated notation differing from the normal atomic symbols‚ these compounds are designated as C3S‚ C2S‚ C3A‚ and C4AF‚ where C stands for calcium oxide (lime)‚ S for silica‚ A for alumina‚ and F for iron oxide. Small amounts of uncombined lime and magnesia also are present‚ along with alkalies and minor amounts of other elements Hydration. The most important hydraulic constituents are the calcium silicates‚ C2S and

01/27/2013 Abstract: What can be found from this experiment is as follows‚ Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse effects on our body. You can measure the water hardness by EDTA titrations.

hydrocolloids. The first combination of ingredients we played with utilized the gel which occurs when alginate is introduced to a calcium. The product‚ which acted as the catalyst for our ideas‚ was designed for gluing meat pieces into uniform blocks‚ cylinders and whole new structures. The product consists of two components‚ one a sodium alginate and one a calcium lactate. While the idea of using these two ingredients to bind proteins was interesting we were more excited by its other possibilities:

Even if you’re being told that drinking milk that contains calcium can help prevent Osteoporosis it isn’t going to magically disappear from your developing of it. To completely understand how to fully prevent yourself from getting Osteoporosis in your life it’s better to first understand what the bone remodeling process is‚ the relationship of calcium and the bones‚ noticeable symptoms and ways to prevent yourself from getting osteoporosis.

the person gets older and there bones will gain strength. The best exercise for the bones is the weight-bearing kind‚ which forces the bones to work against gravity. Certain cells called osteoblasts constantly bring calcium into bones to make them stronger and osteoclasts take calcium from bones. Exercise increases the rate that osteoblasts strengthen bones. Inactivity weakens the bones. So any exercise that places force on a bone will strengthen the bone. Most people achieve their peak bone mass

Hard -120-180 mg/l Very hard 180 + mg/l It is important to study the hardness of water because of the problems it can cause when left untreated. Hard water can cause “scale‚” or build-up in plumbing fixtures and water heaters.3 Scale occurs when calcium carbonate‚ CaCO3 ‚ is deposited as calcite crystals on the inner surfaces of pipes‚ and evaporator surfaces. This occurs when water with a high hardness value is evaporated or heated. This buildup can block pipes‚ make heat transfers in boilers
