Which has homodont teeth?
RRB NTPC (Stage-I)
20/04/2016 / Shift I
2016
✓ Answer:AFish
Many fish have similarly shaped teeth, called homodont dentition. The listed mammals have differentiated tooth types.
112
Which acid is secreted by glandular cells in the stomach lining?
RRB NTPC (Stage-I)
26/04/2016 / Shift II
2016
✓ Answer:AHydrochloric acid
Gastric parietal cells secrete hydrochloric acid.
113
During digestion, the role of bile is:
RRB Group-D
24/09/2018 / Shift III
2018
✓ Answer:BEmulsification of fat
Bile emulsifies fats, facilitating the action of lipase and subsequent absorption.
114
Which enzyme is secreted by the salivary glands?
RRB Group-D
25/09/2018 / Shift I
2018
✓ Answer:DAmylase
Salivary glands secrete amylase for starch digestion.
115
Bile juice is secreted by the _____ in the digestive system.
RRB Group-D
24/09/2018 / Shift I
2018
✓ Answer:ALiver
The liver produces bile, which enters the small intestine through the bile ducts.
116
Which energy conversion is associated with processing food in the body?
RRB Group-D
28/11/2018 / Shift I
2018
✓ Answer:AChemical energy to heat energy
The source selects chemical energy to heat energy. Metabolism of food releases heat; digestion itself mainly breaks food into absorbable molecules.
117
Herbivores require a longer intestine to process _____.
RRB Group-D
28/11/2018 / Shift I
2018
✓ Answer:BCellulose
A longer digestive tract and specialized fermentation regions aid microbial breakdown of cellulose-rich plant material.
118
Herbivores require a longer small intestine to digest _____.
RRB Group-D
20/09/2018 / Shift II
2018
✓ Answer:BCellulose
The intended answer is cellulose. Its breakdown depends on symbiotic microbes in specialized gut regions; the exact region varies among herbivores.
119
What is the common passage for food and air in humans?
RRB Group-D
05/11/2018 / Shift III
2018
✓ Answer:DPharynx
The pharynx is shared by the digestive and respiratory pathways.
120
Tooth enamel, made mainly of _____, is degraded by acid during tooth decay.
RRB Group-D
03/12/2018 / Shift III
2018
✓ Answer:BCalcium phosphate
Acid dissolves enamel minerals, chiefly calcium phosphate in hydroxyapatite.
