Answer:
food web
Explanation:
Food web is an interconnection and assimilation of different good chains. Many food chains are interlinked a hence a food web is created. This represents what is eaten by which organism. The diagram that Ari had drawn is a diagram of a food chain. The grass is the primary source of food in the food web. Rabbit, Mouse, and grasshopper are the animals that eat the grass. The grasshopper is eaten by a shrew and a mouse. The rabbit and shrew are then eaten by the fox. A mouse is eaten by a snake and a fox. This is the diagrammatic representation of a food web.
I'm pretty sure the answer is B
The genetic code is based upon reading 3 bases at a time
there are 4 nucleotides bases in DNA and 20 amino acids .
In order to incorporate all the amino acids we consider 3 bases in genetic code
4 x 4 x 4 = 64
if we would take 2 bases -
4x4 = 16 that would leave out 4 amino acids without a code .
