B. New substances are formed. In a chemical reaction, the starting molecule must be changed or turn into another. For example: rusts that form in a tin can is a chemical reaction. The iron in the can combines with the oxygen in the atmosphere, creating rust (iron oxide), which is a different substance.
Your answer is correct, Vasoconstriction
Answer:
A. loss of sensation to pressure and touch
Explanation:
Posterior column-medial lemniscus pathway also known as the dorsal column–medial lemniscus pathway (DMLP) is a pathway involved in recognition of sensory simulations and is found in central nervous system.
It is involved in conveying different sensations like like touch and vibration from skin and joints. Therefore, it can be said that the pathway plays significant role in perception of sensory information from different parts of the body. If any damage occurs to the pathway it can result in loss of sense of touch and vibration which is ultimately a lack of ability of a person to sense a touch or pressure in the body.
