Answer:
The correct answer would be C. Left untreated, it can cause intellectual disability.
Phenylketonuria (PKU) is a rare autosomal recessive disorder caused by a defect in a gene responsible for making phenylalanine digesting enzyme.
This defect leads to the lack or deficiency of this enzyme in the body. Consequently, phenylalanine builds up in the body.
People with this disorder are usually put on a restricted diet which restricts protein-rich food (such as milk, meat, cheese etc as they contain amino acid phenylalanine) from their meals.
Untreated PKU can cause various complications such as brain damage (intellectual disability), neurological problems, major health and development problems etc.
Answer:
Phosphorylases that selectively add phosphate groups to the Cdc-2 subunit, thereby activating this complex.
Explanation:
The cyclin B-Cdc-2 (also known as maturation-promoting factor or simply MPF) complex is activated when it enters into the nucleus during the G2/M transition in the cell cycle. Cdc-2 is a protein kinase that associates with cyclin proteins. These proteins (cyclins) regulate the cell cycle by activating cyclin-dependent kinases. It is well known that phosphorylation of the Cdc2 subunit at different residues can both activate and inactivate the MPF complex. Moreover, enzymes capable of both inactivating phosphorylases and activating phosphatases have also shown to be able to activate MPF.

Looked them up but you know the internet and what you have been taught could be different so good luck
No we dont. us males have one less.
