Prokaryotes don't have a cell nucleus. While eukaryote organisms have a nucleus. Prokaryotes organisms thus are confined into single-cell organisms
They have the exact relationship
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:
Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.
Explanation:
All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.
