Choose the odd one out from each group and give reasons for exclusion.
1. salivary gland, liver, starch, gall bladder
2. pancreas, liver, stomach, salivary gland
3. absorption, tongue, swallow, taste
4. large intestine, oesophagus, small intestine, rectum
You were blindfolded and asked to identify the drinks provided in two different glass jars. You could identify the first drink as orange juice and the second as strawberry juice. If you were blindfolded, how could you do it?
Answer (2)
The odd one out in each group are: starch (group 1), salivary gland (group 2), absorption (group 3), and oesophagus (group 4). Identifying drinks while blindfolded can be done using sensory cues such as texture, smell, and taste. These methods help to distinguish between different juices based on their unique characteristics.

Let's analyze each group to identify the odd one out and provide reasons for its exclusion:
Group 1: Salivary gland, liver, starch, gall bladder
Odd one out: Starch
Reason: Salivary gland, liver, and gall bladder are organs involved in digestion, while starch is a type of carbohydrate (a nutrient) and not an organ.
Group 2: Pancreas, liver, stomach, salivary gland
Odd one out: Stomach
Reason: The pancreas, liver, and salivary gland are glands that produce digestive enzymes or secretions, whereas the stomach is an organ primarily for digestion but not a gland.
Group 3: Absorption, tongue, swallow, taste
Odd one out: Absorption
Reason: Tongue, swallow, and taste are directly related to the process of tasting and consuming food, while absorption refers to the process of nutrients being absorbed into the bloodstream from the intestines, which is a different part of digestion.
Group 4: Large intestine, oesophagus, small intestine, rectum
Odd one out: Oesophagus
Reason: The oesophagus is part of the digestive tract involved in transporting food from the mouth to the stomach, whereas the large intestine, small intestine, and rectum are involved in further digestion, absorption of nutrients, and excretion.
As for the second part of the student's question, identifying drinks while blindfolded is likely accomplished through the senses of taste and smell. Orange juice and strawberry juice have distinct flavors and aromas that make them identifiable without the need for sight.
