Answer:
A sea sponge 760 million years old
Explanation:
It's unclear exactly how long sea sponges have been around, but they are at least old enough to be the longest-existing creatures on Earth, outside the realm of microorganisms (like bactery). The oldest evidence of a sea sponge found was a fossil discovered just last year in a 760-million-year-old rock. This beat the previous record for oldest sponge fossil, a 635-milloon-year-old sponge discovered in 2009. There may be still older fossils yet to find. But finding an older species is unlikely,as these simple organisms appear to be the progenitors of much more complicated life, including the first multicellular animals.
The presentation of an 18-month-old with hereditary fructose intolerance (HFI), deficiency of aldolase B and low blood glucose levels is due to accumulation of fructose-1 phosphate and the inhibition of glycolytic-gluconeogenic pathways.
Explanation:
Hereditary fructose intolerance leads to deficiency of fructose-1-phosphate aldolase enzyme. This enzyme deficiency leads to accumulation of fructose-1 phosphate in the liver. Fructose-1 phosphate inhibits the action of phosphorylase enzyme which monitors the glycogen to glucose conversion. Since glucose formation is reduced, hypoglycemia and lactic acidosis takes place accounting for the patient’s low blood sugar.

Answer:
Hair and nails are mostly made of protein. Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood.
