The Science of Transportation: Ancient World: The Wheel: • How do they work? Wheels work by rolling along a surface. The curved surface of the wheel reduces the friction between the two surfaces due to a decrease in surface area. With less friction it is much easier to move an object. This is because rolling friction is much weaker than sliding friction. • How did they come to be? The wheel was invented in prehistoric times; as the oldest example of a wheel yet found is from the region of

membrane and explain the process of active and passive transport through the membrane. The plasma membrane is made up of proteins that form pores and channels‚ carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane is a double layer of these phospholipid

1. The cell membrane structure is vital to the life of the cell. The cell membrane is shaped as having a phosphate head at the very outer surface‚ and two fatty acid tails hanging from it. The membrane is double‚ so at the tip of the fatty acid tails‚ there are two more fatty acid tails attached to another phosphate head. This is what it looks like: <br> <br>The reason the cell membrane is shaped like this is mainly to control the water flow in and out of the cell. Water is very important to

resting membrane potential. The resting membrane potential depends on the intracellular and extracellular concentrations of the Na+ and K+ ions. Conductance would change the concentration gradient causing either Na+ or K+ to flow into or out of the cell which would change the resting membrane potential. ACTIVITY 2 Receptor Potential 1. Sensory neurons have a resting potential based on the efflux of potassium ions (as demonstrated in Activity 1). What passive channels are likely found

LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood
