Corn is a popular feed for pigs because it is high in carbohydrates. However, it has a very low level of the amino acid lysine, so farmers usually add high-lysine feeds to the corn. Which statement BEST explains why lysine levels in pig feed are important?

Lysine is important because it is very essential for the body functions of a pig.

Explanation:

Pigs require high levels of lysine, an amino acid. Without enough of this, muscle proteins cannot be formed because amino acids cannot combine correctly. Lysine is essential for body function. Corn diets can only provide pigs with limited lysine and this is not up to what is needed in a pigs nutrition. If the pig is consuming enough lysine then it can use other essential amino acids.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
