Phenylketonuria, or pku, is a recessive genetic disorder in which the amino acid phenylalanine cannot be properly metabolized. children with pku develop mental disabilities. however, the condition can be prevented with a special diet if the disease is caught very early. which of these is a societal decision that could be made based on scientific knowledge about pku? a. some parents choose to serve meals that meet a pku diet even if no one in the family has pku. b. hospitals are required to screen all newborn babies for pku. c. newborn babies who are heterozygous for pku should be treated for the disorder. d. both parents must carry the gene to pass on the pku disorder.

The correct answer is B) Hospitals are required to screen all newborn babies for PKU.

Explanation:

Correct on Edge :)

**please mark brainliest!!

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
