Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Corn is a crop plant. Glow-worms are organisms which give off light. Which process could use these two species to make corn plants which glow?
A
breeding the organisms together
B
causing mutations in the organisms
C
selective breeding
D
transferring genes from one species to another species
Explanation: 

Detailed explanation-1: -Sex and reproduction Corn reproduces sexually and is difficult to propagate vegetatively. Because it has separate male and female flowers it is very easy to control breeding and corn was the first crop for which hybrid seed was produced.

Detailed explanation-2: -The maize (Zea mays) leaf utilizes CO2 to make sugars using the C4 photosynthetic pathway, in which carbon assimilation is essentially split into two distinct cycles within the leaf.

Detailed explanation-3: -Bioluminescence. Bioluminescence involves introducing reporter genes that encode for enzymes (known as luciferases) that can catalyze a light-producing reaction. Luciferases are found in organisms such as fireflies, glowworms, and jellyfish (Contag and Bachmann, 2002; Contag et al., 1998; Greer and Szalay, 2002).

Detailed explanation-4: -Their lights are bioluminescent, which is the natural production of light by an organism created by a chemical reaction. In glow-worms, a molecule called luciferin is combined with oxygen to create oxyluciferin. A chemical reaction with the light-emitting enzyme luciferase produces their illuminations.
