I would say 1 and 4 are the best answers. GMO crops are clones (genetically identical) so it reduces the genetic diversity making crops susceptible to new diseases.
B. chloroplast carrries out photo synthesis
Dolly was a female fin Dorset sheep,
Although it has been claimed that dolly had 3 mothers. one provided the egg, another the DNA, and a third carried the cloned embryo to term.
So therefore, dolly has the genes of different species of sheeps.
Hope this helped!
Answer:
Cool air falls, this is associated with greater pressures areas.
Warm air rises, this is associated with low-pressure areas.
<u>Explanation:</u>
Due to the <em>differences in air pressure</em>, <em>the wind is blown from 'one location to another location'</em>. The cool air is denser than warm air hence the cool air fells which has high density. The warm air has less density and it rises. So the cool air is related to greater pressure areas and warm air is related to lower pressure areas.
