2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

Chapter 6 Newton’s Second Law of Motion-Force and Acceleration The Big Idea: An object accelerates when a net force acts on it. 6.1 Force Causes Acceleration • Unbalanced forces acting on an object cause the object to accelerate. • The combination of foces acting on an object is net force; acceleration depends in net force. • Doubling the force on an object doubles its acceleration. • An object’s acceleration is directly proportional to the net force acting on

How does food move through the body? Food passes through the GI tract‚ and mixes with digestive juices. Eventually‚ it causes large molecules of food to break down into smaller molecules. Then‚ the body absorbs the smaller molecules through the walls of the small intestine into the bloodstream The bloodstream then delivers the small molecules to the rest of the body. After this‚ the food continues into the large intestine‚ and out your body. What happens during the chemical digestion in the

Newton’s second law of motion (Car vs Suv) According to newton’s second law of motion‚ Acceleration is produced when a force acts on a mass. The greater the mass is‚ the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied‚ the acceleration is directly proportional to the force‚ as an example‚ if pushing on an object‚ causing it to accelerate‚ and then you push
