The night was cold and quiet as if the whole city block went to sleep. With nothing but silent raindrops and distant voices‚ I wake up from my four hour slumber and looked at the time. Glancing at the clock on my computer‚ the numbers on the screen clearly says 12:20 pm. “Yeah‚ today is Halloween‚” I think to myself sarcastically.

Juicing is usually done with a machine which turns raw fruits and vegetables into liquid and pulp. The machine chops the fruits and vegetables into tiny pieces and spins them‚ separating the juice

its stomata to allow diffusion of the gas into its leaves. However when a plant does this it also results in loss of water‚ as water vapour diffusing out of the leaves. Lost water however is drawn up through the xylem through a process called transpiration. Water is able to move in opposition to gravity due to the negative pressure of the vessels‚ and the cohesion-tension property of water‚ which allows water molecules to “stick together” and influence the movement of another water molecule. If it

Substantial Content I. Importance of natural method of pest control The problem with broad range conventional pesticides is that they not only kill the bad bugs‚ but they rub out the good bugs‚ too. A garden without natural predators means a world of insects gone wild. There’s nothing left to keep pest levels in check. In fact‚ chemicals can mean double trouble because although you wipe out the first wave of pests‚ the second wave which is not the usual pest‚ but another insect moving into the
