Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima beans. Background Information: In plant growth‚ calcium effects the metabolic process of other nutrient uptake that is vital for growth of the plant. Calcium also strengthens the cell wall structure (It is an essential part of the cell wall);

Photosynthesis in C3 plants and their adaptations to the Mediterranean Climate Abstract. Photosynthesis is the process that plants use to harness the energy of the sun through light and use it to create sugars. Photophosphorylation is the first step of photosynthesis and occurs in the chloroplast. Light is captured by light harvesting complexes. The light excites electrons which excite surronding electrons through resonance induction and excite special pairs of electrons. These electrons help pump

given the bulk density and minimum void content. Equipment * Electronic Balance * Metal Cylinder (AS Compliant) * Metal Scoop * Tamping Steel Rod Test Procedure 1. Determine the weight and volume of the cylinder (for lab experiment written on side). 2. For the mixed aggregates ensure they are well mixed. Now fill the cylinder with the aggregate to 1/3 the height of the cylinder using the scoop. 3. Compact the aggregate with the tamping rod giving 25 strokes without

Research question : How does the different light intensity affect the rate of photosynthesis in plants? Objective : To investigate the relationship between different light intensity (by having the source of light at different distance to the plant discs which is at; 10cm‚ 15cm‚ 20cm‚ 25cm‚ 30cm‚ and 35cm ) and rate of photosynthesis of plant. Introduction : Photosynthesis is the process where light energy is absorbed by green plants to convert the raw materials (carbon dioxide and water) into

Makalah Biologi Percobaan Reaksi Hidrogen Peroksida dengan Katalase Penulis: Jancolin Yani Pendahuluan Seperti yang kita tahu bahwa hydrogen peroksida yang dihasilkan oleh sel-sel didalam tubuh kita akibat metabolism sel akan terpecah menjadi gas hydrogen dan oksigen dengan adanya keberadaan enzim katalase. Zat hydrogen peroksida sangat berbahaya bagi tubuh dalam kuantitas yang banyak oleh karena itu harus dipecah dan dikeluarkan. Sebagian besar zat hydrogen peroksida

Prediction I think that the speed of the cart will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a

constant speed AC motor‚ while the HP stage is driven by a variable speed DC motor. This feature allows variation of the intermediate pressure. Each stage is provided with its own dynamometer. At compressor’s inlet there is an airbox with a sharp-edged orifice for flow measurement. An intercooler is provided between the two stages‚ and an intercooler between the second stage and the pressure vessel. Connected to the pressure vessel is an exhaust pipe with a throttling valve and a calibrated flow
