Hi guys, what exactly do we need to know about transgenic crops in this SD dot point?
- The distinction between genetically modified and transgenic organisms, their use in agriculture to increase crop productivity and to provide resistance to insect predation and/or disease, and the biological, social and ethical implications that are raised by their use
Do we need to know how they are made or any examples? Thanks
For that dot point you don’t need to know how they’re made, but I think there’s a different one that refers to it? You do need to know a bit about how they’re made in order to distinguish between transgenic and gmo though.
You don’t need to know an example for the exam however you might have to for your SAC (I did).
You need to know:
-definitions and differences between transgenic and GMO’s
- their use in agriculture (making crops bigger, making insect that eat them die, making them resistant to insecticide/pesticides so that more can be sprayed on them)
-biological issues - things like wiping out natural plants
-social issues - e.g. farmers who can’t afford the modified plants going bankrupt
-ethical issues - e.g. ‘playing god’
Hi.
I was wondering if anyone knew the answers to these questions(taken from Nature of Biology Edition 5 textbook).
1. What is the main excretory product found in human urine?
True or False
2. Amino acids in excess if needs cannot be stored by animals.
3. The concentration of urea in the blood is equal to its concentration in the urine.
4. Reabsorbtion of substances occurs by both passive diffusion and active transport.
Thanks.
Hey, it’s not very useful for us to just answer them for you. If you want to explain what you think the answer might be/what you think the question relates to then we’ll be able to help
