Mutations In Nature Evolution Of Man
1,542 words... A virus invades a host cell by piercing it at a site called a "receptor. Upon attachment, the virus injects its DNA into the cell, coding it to reproduce more of the virus. After the virus is replicated millions of times over, the cell bursts and the new viruses are released to continue the cycle. The body's natural defense against such cell invasion is to release certain proteins, called antigens, which "plug up" the receptor sites on healthy cells. This causes the foreign virus to not have...

Active Transport Membrane Potential
2,258 wordsEffects Of Solutions On Ion Transport Across Membranes Abstract Concentration gradients exist between two different salt molarity solutions on opposite sides of a membrane. Movement of ions across these sides can be achieved by either active or passive diffusion. In our first three experiments we used these concentration gradients to determine the characteristics of selective permeability of an artificial membrane to potassium chloride (KCl), the potential difference across the skin of a frog, R...
