High accumulation of recombination proteins C. No outcrossing of genes to animals D. No production of human proteinsExplanation / Answer
35. Option A) Are ineffective
Biofilters are used for removal of odour from the air mostly released from sewage treatment plants and cannot remove 90% of the air contaminants because of limited efficiency of the biological components.
36. Option A) Herbicide resistant weeds
When a weed may get outcrossed with a herbicide resistant plant, it may lead to transfer of the resistance from the plant to the weed and hence develop hybrid weeds which will be herbicide resistant.
37. Option C) Both a and b
USPTO issues patents on products as well on product-by-process in which the process or technique by which the product was made can be patented. So, both, process and product patents can be issued.
38. Option A) Mandatory
In July 2016, President Barack Obama signed a bill making this law, asking Food Business Operators to always mention, if the food was a genetically modified food.
39. Option A) Wild Mexican Maize
Wild mexican maize has been polluted with external genes.
40. Option D. Vitamin D
Golden rice is fortified with vitamin A, and night blindness is caused due to absence of vitamin A and maybe corrected by its consumption
