Answer:
Scientists have isolated the gene that produces the bioluminescence protein and inserted the gene into the embryos of tetra fish. This results in tetra fish that produce a green glow.
Explanation:
Tetra fish is a type or an example Glofish that has undergone genetic modifications whereby the gene in jelly fish that produces the green fluorescent protein (GFP) was extracted and inserted into the embryos of the tetra fish thereby causing them to glow or fluoresce in the presence of Ultraviolet light or natural light. The genetically modified tetra fish passes this fluorescent gene from one generation to another.
The aim of this genetic modification in tetra fish was to be able to detect water pollution in the sea using the glow of the tetra fish.

Skin and Integumentary system protects by forming a selective barrier.
<u>Explanation</u>:
Multicellular organisms unlike unicellular organism have a variety of systems each having a different function. The body of multicellular organisms is covered with epidermis or skin which is known as largest organ of the body. The skin consists of many sensory receptors and protects by enclosing muscles and other body tissues. While Integumentary system is made with skin and its various appendages like hair, feathers, nails etc. with receptors and secretary pores and protects the body from pain.
