depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface becomes less positive. Additionally‚ when depolarization reaches a certain threshold‚ an action potential is initiated and the polarity of the membrane reverses. 4. What is the difference between membrane irritability

“Biology Article” Barbara Manley Professor Trinna S. Johnson Introduction to Biology May 9‚ 2013 A New System for Cancer Detection This article summarizes a new technique that would allow for cancer cell detection without being invasive to a person’s body. It states that currently‚ human cancer cell detection is conducted through a person being cut on or biopsied. This new procedure allows for humans bodily fluids to be utilized in detecting cancer cells. Chandra states‚ “While current

it has evolved to adapt to most environments to withstand any other organisms. In the 1930’s Alexander Fleming‚ Ernst Chain and Howard Florey discovered an antibody which could destroy most bacteria and assist to fight infectious diseases. Many experiments were completed to understand the full impact antibiotics had on humans and how much was needed to rid someone of disease. Drug companies began to mass produce Antibiotics as a means of curing infections and diseases‚ but only a few years later scientists

3.8.1.2 Leaf area and leaf area index (LAI) Leaf area of five randomly selected plants‚ was measured with the help of leaf area meter (Model LI-3100‚ USA) at 20‚ 40 and 60 DAS by destructive sampling from all leaves of the five sample plants (Sticker et al.‚ 1961). Plants were cut at the soil surface‚ leaves were separated from the plants‚ covered with blotting paper to keep the leaf intact and retain its original shape and were brought to the laboratory. Leaf area was measured immediately after
