An investigator wishes to use animals in an experiment that involves category B, C, and D activities performed on the same anima
Arte-miy333 [17]

Answer:

Category D

Explanation:

In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.

D.Amylase is deactivated by the low pH in the stomach.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides

.E. Monosaccharides are absorbed through the intestinal wad

Explanation:

Carbohydrates are complex or large molecules are they are found in rice, bread e.t.c

Digestion of carbohydrates start from the mouth through a process called mastication i.e chewing of the carbohydrates. The salivary gland then secrete the salivary amylase which act on the chewed carbohydrates. The salivary amylase breaks down amylose and amylopectin present in starches into smaller chains of glucose which is called dextrins and maltose. When it get to the stomach, the amylase cannot further break it because it does not work in acidic conditions. The substance form chyme in the upper stomach and pancreatic enzymes act on it to break it down into simple sugar glucose. The pancreatic enzymes include sucrase, maltase and lactase.

Sucrase breakdown sucrose into glucose and fructose, maltase breakdown maltose in two molecules of glucose and lactase breakdown lactose into galactose and glucose. The simple sugar are then absorbed into the blood through the intestinal wall.
