What are two ways of producing transgenic crops?
Transgenesis can be facilitated by:
- plasmid vectors
- viral vectors
- pronuclear injection
- protoplast fusion
- ballistic DNA injection
Multiple cropping is the agricultural practice of growing two or more crops in the same field during the same growing season. This type of polyculture can be categorized into two ways: double-cropping, where the second crop is planted after the first is harvested; and relay cropping, when the second crop is planted before the first has been harvested.
What are scientists more likely to learn from transgenic animals that from transgenic bacteria or transgenic plants?
How humans genes function. Animal biology is much more similar to that of humans than the others. This means that animals and humans (we are animals BTW) share a more recent genetic relative than the with the other two types of organisms. All life is related, that's why studying bacteria and viruses is very interesting. But from a human medicine standpoint animal studies are the most useful. Yhin Ramirez
There are at least two general ways of doing this: move an electrical conductor through a magnetic field use motion to accumulate electric charges The first of these is exploited in dynamos for producing direct current and in generators for producing alternating current electricity. The second is mainly a curiosity that is probably best represented by the Wimshurst machine.
Agriculture in the south is actually very similar to that in the northeast but there are some differences such as in the south there is a lot of cotton and peanut production with in the northeast there is a lot of production in fish. Beign with these two differences the equipment used in producing and harvesting these crops are different as well.
Rabi crops and Kharif crops. Kharif crops are grown from June to October. Rabi crops are grown from November to April. There are more possibilities than those just stated above. The other possibilities you may be referring to are: 1. Grain and legume/oilseed crops 2. Conventional and organic crops 3. Cash crops and feed crops
