means lethal dose. LD50 is the amount of a material, administered at once to
cause the death of half (50%) of a group of test organisms. A test which shows that LD50 of a certain
chemical is 20 mg per kg means that 20 milligrams of that chemical for every 1
kilogram body weight of the test animal when administered in one dose, causes
the death of 50% of the test group.</span>
Answer:
Quickly
Explanation:
The more quickly that a new generation of organisms develops and reproduces the faster that you will be able to observe whether the new traits have been passed on to the new generation or not, and so on if you want to see this effect over several generations. For example, if you have genetically modified corn, you just have to wait one year to see if next year's generation of corn will have the modified trait or not. Conversely, if you geneticall modify an apple, you have to wait several years until the new generation of apples mature and are able to flower and produce the next generation of apple embryos.
