c. precognition
d. telepathy

Answers

Among the options given above, 'hearing' is the one that is not an extrasensory power. Clairvoyance, Precognition and Telepathy are extrasensory powers. Therefore, the answer to this question is letter "B. hearing". I hope this helps. 

Answer:

Option b=> hearing.

Explanation:

When information are getting to individual without the person using his or sense organs such as the eyes(vision), ears(audio/hearing), skin(feeling), tongue (tasting) and nose(perceiving smell) then we say that the individual has '' psychic powers'' or the sixth sense.

extrasensory power.

If you look at the meaning of option (a), that is clairvoyance, it is more of seeing the future which can never be seen with our normal eyes, therefore, it is an extrasensory power

Option (b), can be done with our normal ears, hence, it is not an extrasensory power.

Option (c) and (d) that is precognition(knowing what is coming without seeing with norm human eyes) and telepathy(being able to read People's mind) respectively are both extrasensory powers.

What do they mean when people say that digestion starts in your mouth?

Answers

The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. Hope I’ve helped ;)

Answer:

When you chew, it is a sort of digestion, and it starts the whole process.
