Selective breeding. The process in which two animals which posess the desired qualities are mated to produce offspring which posess these characteristics themselves.
No one discovered genetically modified organisms. Such organisms are created by people working in laboratories. In 1953 it was discovered that DNA is the material that carries genes, the information that defines and structures each organism. For the next 50 years people worked to understand DNA and eventually learned how to modify it, in some circumstances. When such a modification is successful, the result is an organism that has been genetically modified - a genetically modified organism.
he invented them he didn't improve them,before there was something else(sorry i have forgot the name) but he was the 1 who invented dynamites.
there are lots of techniques by which we can improve the life of a timber like seasoning of timber,by applying different types preservatives coat before it is used.
There are people who will say GMO foods are closely regulated, but the FDA has declared them to be "substantially equivalent" to their non GMO equivalents. They have a voluntary consultation process for the developing company to consult with them before new GMO varieties are approved, which is not actually regulating them at all. The approval process for genetically modified animals appears to be much tighter.
Exposure to mutagens, such as chemicals, radiation ect. May I ask why you would want to do this?
Farmers, and ranchers, and gardeners have been genetically modifying plants and animals since the days of Gregor Mendel before 1900. Over one hundred years. You probably can't buy a Petunia that hasn't been genetically modified sometime along the way. So is it a 'real' Petunia or not? If it looks like a chicken and clucks like a chicken and walks like a chicken and tastes like a chicken; it's a chicken.
Some believe it's better to experiment on animals so if anything harmful comes from the product, they can improve it before allowing humans to use it. However, it's still considered to be bad.
There is food all over the world and before they became farmers they probably ate what they could find.
They had to find thing the old fashion way.
Before the industrial revolution, farmers do not use capital, therefore to make their work easier, they make use of their animals to plough their land.When they use their animal in ploughing their land,it looks just like it had been ploughed by machines,but it takes alot of time for farmers to plough the land within one day.
Before the railroads were built, farmers had to haul their crops on wagons. This was one reason the farmers who wanted to export part of their crops settled near rivers or near the Atlantic ocean.
Yes, farmers in the 1930s often had root cellars to store vegetables, fruits, and other food items. These underground spaces helped to keep produce cool and extend its shelf life throughout the year.
Farmers would have used horses to pull carts, ploughs and other farm machinery.
Before tractors farmers used horses, mules, and oxen to till the fields.
1. the majority of people were farmers. 2. made most of their things by land. 3. Farming land turned into towns. 4. Power was supplied by humans and animals.
