Answer:
Corn crop is resistant to herbicides because they are genetically modified through genetic engineering. There are some bacteria which are resistant to herbicides i. e. no effect of chemicals on that bacteria. So the biotechnologist take a gene from this resistant bacteria and induced it in the corn plant which becomes the part of their genetic makeup. So when we apply herbicide, the gene produces some enzymes which cancel the adverse affect of herbicide and only weeds are affected.
Not all veins and arteries travel together but most of them do. Reason being that veins don't have good means of pumping up to the heart and this is facilitated by arterial pulsations.
Muscular contractions help venous to pump blood because when muscle contract venous sinuses are caused to contract and blood be pumped up. Where there is no gravity muscular contraction is important because of the veins of the lower extremity.
