I chose a simple procedure that can be carried out using materials that are easily found in the home. The exception is Toluidine blue which however can be bought in shops that sell materials for chemical and biological laboratories. Almost all microscopists have this dye or another nuclear colorant.

Keeping conditions inside the body the same is called homeostasis. It’s not easy. Lots of things have to happen‚ e.g. energy transferred between body and environment‚ carbon dioxide is a waste product of respiration and has to be transported by the bloodstream to the lungs where it is breathed out‚ waste and waste products are filtered out of the blood and excreted in the urine. An incubator has a temperature sensor‚ a thermostat with a switch and a heater. Negative feedback happens when one factor

Makenzie Ann Cox October 22‚ 2014 Biology 1112.317 Lab Report Amounts of Carbon Dioxide/ Oxygen Animals are Producing/ Consuming Introduction Every cell needs a source of energy in order to perform their daily functions. However the process to get this energy is different for plant and animal cells. Plants cells undergo a process called photosynthesis where light energy from the sun is used to convert carbon dioxide and water into glucose and oxygen. For animal cells‚ the process is known as cellular

Lastly‚ an isotonic solution entails no net movement of water across a semi-permeable membrane as the two substances involved display osmotic equilibrium.
