Answer:
Option D, Gastric Juices
Explanation:
The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.
Hence, gastric juice does not belong to second line of defense.
Thus, option D is correct.
Fatigue can have causes that aren't due to underlying disease. Examples include lack of sleep, heavy exertion, jetlag, a large meal, or aging.

Answer:
B. Dehydration synthesis
Explanation:
Adenosine diphosphate (ADP) and Adenosine triphosphate (ATP) are currencies of energy found in plant and animal cells. They are also nucleotides found in the mitochondria in the cytoplasm of the cell.
Cellular oxidation in a cycle of enzyme-catalyzed metabolic reactions, known as Carboxylic/Krebs cycle. ATP synthase is a huge molecular complex and has a function of catalysing the addition of a third phosphorous group to form ATP through rehydration synthesis. The reverse of this reaction; production of ADP from ATP is called hydrolysis.
