They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences.

Organ where carbohydrate absorption occurs
Rina8888 [55]

Answer: Small intestines

Explanation: Digestion of carbohydrates begins in the mouth mechanically and through salivary amylase. It passes down to the stomach by parastalsis, digested further and goes to the small intestines where their absorption begins. Carbohydrates are a source of glucose, that most organs use as their primary energy source. Indigestible carbohydrates and fibers travels down to the large intestines where they are digested by bacteria or eliminated as waste through the anus.

The small intestines consist of microvilli that increase surface area for maximum nutrient absorption. Carbohydrates are absorbed by the small intestines via the jejunum, taken to the blood stream then transported to the liver where glycolysis and most metabolic pathways take place, for energy production.

Acidity is responsible for ulcer, dyspepsia, heartburn and the formulation of the ulcer. One way to experiment on how the acid is neutralized is by using vinegar and starch.

Cell biology techniques, on the other hand, want to know what's going on inside intact cells.
