The disease, Amyotrophic Lateral Sclerosis, better known as Lou Gehrig's Disease
... is Lou Gehrig's disease. Lou Gehrig was a hall of fame baseball player who played with Babe Ruth on the Yankees. He once hit four homeruns in one game. He fell victim to ALS in the late 1930's. ALS was discovered in Paris, France in the early 1870's. Jean-Martin Charcot ...
The Endomembrane System
... plasma membrane. The nuclear envelope (found around the nucleus) is made of a double phospholipid bilayer, it has two double layers of phospholipids and many pores. The Nuclear envelope separates the contents of the nucleus from the cytoplasm while still allowing the nucleus and the cytoplasm ...
