The correct answer is - B. Beak size determines what the bird can eat.
The beak of a bird can come in many different shapes and sizes. It can be pointy, long, short, rounded, scythe-like, thin, thick... All of those shapes and sizes have a specific role, and that role is to enable the bird to feed itself with certain type of food source. Every food source requires certain type of beak in order for the bird to be efficient in getting its nutrition, so depending on hat the bird eats, we can easily see a pattern in the beaks, where birds that eat nuts have one strong and shorter beak, the ones that eat warms and insects have thin, pointy one, the predator birds have claw like, sharp beak...
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.
Pigment molecules absorb light energy.
