Glyphosate resistance in plants can be generated by expressing in them transgenes that serve one of the following three purposes: 
(1) Overproduction of EPSPS enzyme 
(2) Encode an EPSPS enzyme that is tolerant to glyphosate
(3) Produce an enzyme that inactivates glyphosate
(4) Use a combination of the strategies (2) and (3)
Which of the above strategies can be used to make plants glyphosate resistant?

Mechanical barriers provide a first line of defence against insect pests and pathogens, these mechanical barriers developed by plants;

                   COLUMN A  

                     COLUMN B

A. Thorns

i) It can be found on the stem and petioles of roses and are formed by the epidermis

B. Spines

ii) Found on a lemon tree (Citrus sp.) are modified branches, as can be seen by their position in the axil of a leaf

C. Prickles

iii) Found on shoot and leaves of tomato (Solanum lycopersicum) are derived from epidermal cells

D. Trichomes

iv) which are characteristic of cacti (Opuntia spp.) in the New World, are modified leaves

Match correctly following combination of barrier developed by plants ;
