Investigate factors affecting cell membrane permeability in beetroot. Research Question: How does variation in temperature affect the permeability of cell membranes? Background Information: In this investigation I will want to identify how variations in temperature effect the permeability through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC

Basic Mechanism An autoimmune disease occurs when the body produces an abnormal immune response against self antigens. It is caused by failure of the tolerance processes to protect the host from the action of self reactive lymphocytes. An organ-specific autoimmune disease involves gradual damage to cellular structures and is replaced by the compensating connective tissue which depletes the function of the gland/organ. Type 1 diabetes (TD1)‚ is an organ specific autoimmune disease characterize
