Answer: RadioImmunoassay
Explanation:
RadioImmunoassay is a technique used in the measurement and comparison of hormones. It helps to identify difference in the hormone concentration of various species. It makes use of Anti-bodies directed against the hormones and the radio-labelled forms of hormones. A standard curve that contains a known amount of hormone is then use to compare and calculate measurements of the new hormones.
Answer:
The reference value that is expressed as a percentage of total calories is called as % daily value.
Explanation:
The % daily value tells about the the nutrients which are present in a single serving of food. They are mostly present on the Nutritional Fact Label for foods. The standard for the % daily value is set to 2000 calorie. 2000 calories are required for a healthy adult diet. But even if a person has a calorie uptake lower or higher then that, he/she can still use the % Daily Value as a guideline.
For example, If 2% vitamin C is written on a label than it defines that one serving of that product supplies 2% of the vitamin C that you require each day.
Answer:
D. chemical digestion
Explanation:
In chemical digestion, large food molecules are broken down into smaller particles thanks to the action of enzymes present in the digestive juice, undergoing changes in their chemical composition.
Chemical digestion is a process that occurs with the action of enzymes. It starts in the mouth with the action of the enzyme amylase, which is present in saliva and digesting starch. In the stomach, there is the action of gastric juice, consisting of hydrochloric acid and the enzyme pepsin, which acts on protein digestion. In the small intestine, the food undergoes the action of substances produced by the pancreas (alkaline substance containing trypsin and chymotrypsin, enzymes that act on proteins) and by the liver (bile, which contains salts that act on the digestion of fat, is produced by liver but is stored and concentrated in the gallbladder).
