Answer: Option A.
Different beaks were available
Explanation:
Variation is the difference between traits, cells, or characteristics between organisms of any species which is caused by change in genetic information or effect of environmental factors on the expression of genes.
From the question, different beaks were available because there is variation or differences in shapes, sizes and expression.
Answer:
At the interior side.
Explanation:
Nonpolar amino acids of a protein more likely to be found at the interior side of the soluble proteins where they are far from the water because water is a polar molecule and only polar amino acids of protein can interact with the water so that's why the polar amino acids are present on the surface of soluble proteins and the nonpolar amino acids of a protein are present at the interior side of the soluble proteins due to its nonpolar nature.
In aerobic respiration, the final electron acceptor in the electron transport chain is oxygen. It accepts two electrons and a molecule of water is formed as a by product.
In anaerobic respiration, the final electron acceptor in the electron transport chain is pyruvate. Anaerobic respiration commonly occurs in the muscle tissue of animals as a result of intense activity or exertion. Pyruvate is used as makeshift electron acceptor in place of oxygen and is reduced or converted to lactic acid.
