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 ;

With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction and load each one into a separate well of an agarose gel, and then run the gel.
