Answer:
Water is the common solvent of the body
Water is a polar, covalent molecule
The high heat capacity of water relates to its ability to absorb significant
amounts of heat before changing one degree celsius
.
Acids have a higher concentration of free H+ than are found in bases
Explanation:
Water is also called universal solvent because it can dissolve a large number of polar compounds due to its polar nature. In water, covalent bond is present between hydrogen and oxygen due to which partial positive charge occurs on hydrogen and partial negative charge appears on oxygen atom due to difference in electronegativity values. Acids has high concentration of proton (H+) while bases has high amount of OH- ions.

Explanation:
Answer:
The correct option is A.
A. blocking transmission of impulses from the spinal cord to thalamus
Explanation:
Local anesthetics, like lidocaine and novocaine, reduce the perception of pain by blocking transmission of impulses from the spinal cord to thalamus because local anesthetics they first bind to ion channel in the nerve cell and then inhibit function of the ion channel present in the membrane of nerve cell known as sodium channel. This later cause blockage of nerve impulses at the site where the injection was given from the spinal cord.
