Why was it made? Bt corn was produced to combat the species of caterpillar pest called Lepidopteran. It was made to take care of one of these types of caterpillars specifically‚ the European corn borer. Bt corn is made to include the gene from Bacillus thuringeiensis. This bacterium lives naturally in soil. It produces a toxin that becomes a pesticide. Bt corn can produce this type of pesticide in its pollen. (para 1). How is it made? When Bt corn is made the producers use a specific protein that

1. BIOLOGICAL CLASSIFICATION Aristotle’s classification - Aristotle was the earliest to attempt a more scientific basis for classification of organisms. - He classified plants into trees‚ shrubs & herbs and animals into two groups‚ those which had red blood and those that did not. Two-kingdom classification - In Linnaeus’ time Two Kingdom classification (Kingdom Plantae & Kingdom Animalia) was developed. Drawbacks of 2-kingdom classification Prokaryotes (Bacteria‚ cyanobacteria) and eukaryotes

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions
