Explanation:
the answer is C because with us destroying habitat of animals that depend on it for their survival
Answer :
The correct answer is due to incorrect position of thermometer .
Distillation is process of separating two volatile liquids on the basis of their boiling points .In involves the following set up ( shown in image )
Since the Boiling point is found is 116-117 C which is near to 124 C , also the purity was checked and thermometer was calibrated .
So the only error could be possible is position of thermometer .
The position of bulb of thermometer is very important to get an accurate reading of boiling point .The vapor so formed should touch the side walls of bulb as soon as they are formed .
May be the bulb of thermometer was kept far from the vapors formed by liquid so, s<u>ome of the vapor before reaching to bulb start condensing and their Temperature decreases </u>.
Hence , the temperature shown by thermometer was decrease than actual boiling point due to incorrect position of thermometer.
Answer:
The structure that is located between the auricle and the eardrum is the ear canal.
Explanation:
The ear canal, or external ear canal, is a a tubular hole about 30 mm long that runs from the auricle to the eardrum, forming part of the external ear.
Its function is to conduct sound, in the form of vibrations, from the outside to the eardrum. It also has the function of producing a viscous secretion called cerumen, capable of trapping dust particles and small foreign bodies.
Other options are not correct because:
- <em>Stirrup is located in the middle ear, along with the anvil and hammer.
</em>
- <em>Cochlea is in the inner ear and continues with the auditory nerve.</em>
The reaction is a decomposition…
… because one substance is forming two other substances.
It is also a <em>reduction-oxidation reaction</em> because the <em>oxidation number of N decreases</em> from +5 to +3 and the <em>oxidation number of O increases</em> from -2 to 0.
