1. Temperature: Put some hot water‚ warm water‚ and cold water in three bowls. Just use water from your faucet‚ and please be sure that the hot water is not too hot to touch! Place a finger in the hot water and a finger of the other hand in the cold water. After a few seconds‚ place them both in the warm water. Describe the sensations. Can you trust your senses for measuring temperature? Explain your answer. Placing finger A(pointing finger on left hand) in the “hot” water‚ my finger felt a hot

Saline Salt Company Analysis The Saline Salt Company production process was simple. Their process involved extracting salt from six tanks of 900‚000 cubic feet of seawater which could only be held on a large plot of land. As land becomes more valuable and rarer‚ expansion of the existing method becomes very difficult. Saline Salt Company could not compete with other companies that were producing larger amounts of salt in shorter amounts of time. Saline Salt Company did not expand as the needs

When a beetroot cell is exposed to various kinds of temperatures‚ its plasma membrane is affected and may change in structure resulting in the leaking of betacyanin. If the temperature changes‚ then I would expect to observe that there would be a change in the concentration of betacyanin that has leaked from a beetroot cell. In specific‚ at high temperatures‚ the phospholipids that make up the plasma membrane of the beet root cell become progressively more destabilized causing them to transform into
