Discuss how the therapy for PKU would be different if the disease was not caused by the essential amino acid phenylalanine, but rather by a non-essential amino acid. Would the disorder be potentially more or less life-threatening? Explain your reasoning
What will be an ideal response?
Because phenylketonuria (PKU) is caused by the inability of the body to metabolize the essential amino acid phenylalanine (which must be ingested in the diet), it can be treated by limiting the intake of phenylalanine in the foods that are eaten. However, if PKU was caused by a non-essential amino acid, the molecule would be manufactured by the body rather than ingested. The disorder could not be treated by changes in the diet and would, therefore, be much more challenging to treat and possibly more life-threatening.

In western Sweden, coastal marine ecosystems have been exposed to discharge of nutrients over several decades. As a result, algal blooms are more common.Algal mats on the sea bottom limit sunlight and alter the amount of dissolved oxygen in the water. Additionally, some algae produce toxic compounds that can enter shellfish. Furthermore, the decomposing algae produces a strong odor. Which statements below correctly match the outcomes to their effects on value of the ecosystem? Check all that apply.
_____ Aesthetic value is lost because the algae makes the beach ugly and smells terrible. _____ Indirect economic value is lost because fisherman cannot catch their usual fish. _____ Direct economic value is lost because the toxic shellfish cannot be eaten. _____ Aesthetic value is gained because the algae could be used for biomass. _____ Direct economic value is lost because the properties near the beach aren’t as desirable.
