Why didn't farmers used to eat the best of the seeds that they produced?complete the selective breeding simulation until you have successfully produced the largest crop possible. 2. how many tries did it take you to successfully produce the largest crop possible using selective breeding? engineering a crop complete the transgenic manipulation simulation and answer the questions as you complete the activity. 3. what is the purpose of the activity "transgenic manipulation? " 4. what does bt stand for? why would someone want this gene in a crop 5. what is a vector?6. why was the vector inserted into the

1. The farmers did not eat the best of the seeds that they produced because they they offered them as sacrifices and used them to plant for the following season.
4. Bt stands for Bacillus Thuringiensis. People want this because it's a Gram-positive, soil-dwelling bacterium, commonly used as a biological pesticide. With Bt plants can protect themselves from insects.
5. A quantity with more than one element. Vectors are used in science to describe anything that has both a direction and a magnitude.
6. This action required the genetic alteration of a bacterial cell by the uptake of DNA isolated from a genetically different bacterium and its recombination with the host-cell genome. The first evidence from the experiments provided that DNA is the genetic material.

Hope this helps!! (If not sorry!) Also i'm sorry idk 2 or 3 but hope you find out!
