During the swallowing reflex .
A. the tongue closes off the pharynx
B. the epiglottis closes off the glottis
C. breathing rate increases
D. the esophageal sphincter closes off the esophagus

The correct statement will be - B

The epiglottis closes off the glottis.

Explanation:

During the swallowing reflex - the epiglottis closes off the glottis.

Our respiratory and digestive system shares a common path. At the time of swallowing something, the epiglottis closes off the glottis which helps the food to go downwards further easily. Otherwise, there is a chance that the food can enter the windpipe and can choke a person. Sometimes this could be fatal.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
