Answer: It is an example of TRISOMY 21.

Explanation:

Trisomy 21 is a genetic condition in which 21 chromosome fail to separate during the growth of egg cell and sperm which make either of the two to an extra copy of chromosome 21. This is also known as down syndrome. This lead to slow and in appropriate mental development in affected individual.

Phosphoriboglycinamide transformylase(GART) is agene found on chromosome 21, which lead to down syndrome is an example of trisomy 21.

eimsori [14]

Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>

<u></u>

  • The process by which an embryo transforms into a fetus is known as embryogenesis.
  • The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
  • Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
  • The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
  • An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.

kap26 [50]

Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.

Explanation:

Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.

The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.

But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.
